Inspired by the Aurora Borealis in the night sky, frequently seen in Norway, this tartan takes its colours from the Norwegian flag (red, blue and white) and the yellow, white and black hues for the varying colours of the Aurora Borealis in the night sky.

The auroras, known as nordlys in Norway, are a treasured natural phenomenon, drawing countless visitors to witness their ethereal beauty. This dazzling display is created when fast-moving electrons from Earth’s magnetosphere collide with oxygen and nitrogen molecules in the upper atmosphere, producing a kaleidoscope of colors: greenish-yellow or red from oxygen, blue from nitrogen, and magical shades of purple, pink, and white from color mixing.

The auroras have inspired myths across many cultures. In Norse mythology, the lights were thought to reflect the shields of the Valkyries, creating the legendary “Bifrost Bridge,” a glowing pathway that guided fallen warriors to Valhalla. For the Sámi people, indigenous to the region, the auroras were seen as a sacred phenomenon, to be admired in silence and respect. Remarkably, auroras have even been known to produce sounds—faint crackles, hisses, or even whistles—adding to their otherworldly allure. 🇳🇴 ❤️ 💙 🖤 💛 🤍

Of the many names for full moons that occur in March, the "Worm Moon" takes its name from the time in the Northern Hemisphere, when earthworms begin to emerge from the thawing ground, signaling the quiet arrival of spring and providing food for returning birds.

The upcoming Total Lunar Eclipse, often referred to as the “Blood Worm Moon,” will occur on March 2–3, 2026, when the full Worm Moon reaches its peak. During this event, the Moon will pass completely through Earth’s umbral shadow, producing a dramatic copper-red glow. Totality will last for just under an hour (approximately 55–60 minutes), with the entire eclipse sequence unfolding over several hours as the Moon moves through the penumbral and umbral phases.

The eclipse will be visible across much of North America, the Pacific region, Australia, and parts of East Asia, making it one of the most widely viewable lunar events of 2026.

Lunar eclipses occur when the Sun, Earth, and Moon align so that the Moon passes into Earth’s shadow. That shadow has two parts: the lighter penumbra (a partial outer shadow) and the darker umbra (the full inner shadow). During a total lunar eclipse, the Moon traverses both regions, leading to the characteristic dimming and reddening of its surface.

The reddish hue observed during totality — often called the “Blood Moon” effect — results from Earth’s atmosphere filtering out shorter-wavelength blue light while bending and allowing longer red and orange wavelengths to reach the Moon. This same scattering effect gives us the warm colors of sunrise and sunset.

This Umbra Illusion tartan uses — among other shades of black, white, and grey — a particular shade called “Eclipse.” 🖤 🤍 ❤️ 🪱 🪱 🪱 🌘 🌑 🌒

Astronomical tartan alert! Saturn’s largest moon, Titan, was discovered today on March 25, 1655, by Dutch astronomer Christiaan Huygens, whose work was inspired both by Galileo’s 1610 discovery of Jupiter’s four largest moons and by his own improvements to telescope design.

Today, we know that Saturn is orbited by at least 146 moons, over 50 of them officially named—quite apart from the hundreds of smaller moonlets embedded within its rings.

Titan stands out not only as Saturn’s largest moon but also as the second-largest in the entire Solar System, even surpassing the planet Mercury in size.

Remarkably, it is the only moon known to possess a substantial atmosphere.

Many of Saturn’s moons take their names from the Titans of Greek mythology—the pre-Olympian deities born of Uranus (Sky) and Gaia (Earth), and kin to Cronus.

Titan itself is a fascinating world of water ice over a rocky core, with a surface marked by liquid hydrocarbon lakes, cryovolcanic vents, and contrasting regions of bright and dark terrain shaped in part by impact cratering.

This tartan reflects Titan’s striking landscape and atmosphere. Designed for Charles Cockell of University of Edinburgh, it celebrates science and exploration of Saturn’s largest moon.

Its colours tell Titan’s story: brown for the hazy methane-rich atmosphere, dark brown for complex hydrocarbons and methane lakes, white for water ice, blue for a hidden subsurface ocean, and green for the potential building blocks of life and future exploration. 💛 🤎 💙 💚 🤍 🌕 🔭 🪐

In Scottish Gaelic folklore the Northern Lights are known as the Na Fir Chlis – “the Nimble Men” (also known as the Merry Dancers). The Lights were described as epic fights among sky warriors or fallen angels. And according to legend, blood from the wounded fell to earth and spotted the “bloodstones” (a variety of jasper) found in the Hebrides.

In Scotland, the aurora most often glows in soft, shimmering green, the signature colour dancing low across the northern sky. During stronger displays, a faint red may hover above it like a distant ember, while hints of purple and violet flicker along the lower edges. At their most vivid, these colours can blend into delicate flashes of pink, creating a layered, otherworldly glow, beautifully illustrated in this namesake tartan.

The Isle of Skye is one of Scotland’s most beloved spots for watching the aurora borealis, thanks to its remote location, minimal light pollution, and sweeping northern horizons over the sea. On clear nights with strong solar activity, the lights can often be seen dancing above landmarks like the Quiraing, the Old Man of Storr, or along the Trotternish Peninsula. Skye’s rugged, open landscapes make it especially rewarding for aurora watchers

Another favourite viewing spot is on the Isle of Lewis, home of the Callanish Stones. These stones were erected between about 2900 and 2600 BCE, making them older than the main stone phases of Stonehenge. Constructed from local Lewisian gneiss, the site is more than a simple stone circle: it features a tall central monolith surrounded by a ring of stones, with rows extending outward in a cross-like layout. The northern row forms a kind of avenue, suggesting movement through the space may have been intentional. Archaeological evidence indicates the site was used for ritual rather than daily living, and around 2000 BCE a chambered cairn was added in the center, along with signs of burning and pottery that point to ceremonial activity.

The stones are also closely connected to the sky, particularly the moon. Many researchers have argued that the layout aligns with the moon’s extreme rising and setting points during the major lunar standstill cycle, which occurs roughly every 18.6 years. While the exact precision is debated, there is general agreement that the builders were carefully observing celestial patterns. Callanish is not an isolated monument but part of a wider landscape of nearby stone settings, suggesting a broader ceremonial network. Over time the site fell out of use and became buried in peat until its rediscovery and excavation in the 19th century, revealing the full structure we see today. 💚 💙 🖤 🤍 💜 ❤️ 💫 ✨ ✨ ✨

Apophis (officially 99942 Apophis) is a near-Earth asteroid discovered in 2004. It gained attention due to initial calculations suggesting a potential close encounter with Earth in 2029, and again in 2036, raising concerns about a possible impact. Named after the Egyptian god of chaos, darkness, and disorder, Apophis is about 370 meters (1,210 feet) in diameter.

Here are its stats:

Apophis – April 13, 2029 Close Approach Object Name: (99942) Apophis

Closest Approach: April 13, 2029

Distance: ~0.000254 AU (~38,000 km / ~23,600 miles)

Size: ~340 meters in diameter

Speed at Approach: ~7.4 km/s (relative to Earth)

Rarity/Impact Risk:

Originally given a Level 4 on the Torino Impact Hazard Scale (the highest ever recorded).

It had a small chance of impacting Earth in 2029 or 2036, but follow-up observations have ruled out any impact for at least the next 100 years.

Rarity Score (Unofficial): 9 or 10 out of 10 for rarity (due to proximity and size)

****

It will pass closer than many satellites orbiting Earth — and be visible to the naked eye over parts of Europe, Africa, and Asia.

Initially estimated to have a 2.7% chance of hitting Earth in 2029, a very high probability in NEO terms.

****

Allegedly, once the data became more publicly scrutinized, additional calculations were made that ruled out any significant risk of collision ... hmmm ...

Regardless, defy destiny and dangerous space rocks by kilting up in this beautiful tartan with all the spirit of one's Celtic ancestry! 🖤 🤍 💚 🖤 🔭 😲 🪨 🪨 🪨

Fortunately for astronomers and sky-watchers alike, there’s no reason not to kilt up properly for a night under the stars—there are plenty of tartans that take their inspiration from the galaxy itself.

In the 1920s, Edwin Hubble demonstrated that the “spiral nebulae” seen through telescopes were not small objects within our own galaxy, but entirely separate galaxies far beyond the Milky Way, dramatically expanding the known scale of the universe. He also showed that these galaxies are moving away from us, and that their speed increases with distance—a relationship now known as the Hubble–Lemaître Law, providing the first clear evidence that the universe is expanding.

The Hubble Space Telescope, named in his honor, was launched on April 24, 1990, aboard the Space Shuttle Discovery and placed into orbit about 340 miles above Earth, offering an unusually clear view into the depths of space. From that vantage point, it has produced some of the most detailed and striking images of the cosmos, steadily refining our understanding of how the universe is structured and how it evolves.

Among its many observations is the long-term approach of the Milky Way and the Andromeda galaxy—an eventual merger that is already underway in slow motion. In studying Andromeda, Hubble revealed an interesting detail: although the two galaxies are broadly similar in age, the stars in Andromeda’s outer halo are noticeably younger than those surrounding our own. The likely explanation is a more turbulent past, with Andromeda having absorbed a number of smaller galaxies over time.

Through Hubble’s lens, the universe presents itself not as something static, but as an active, shifting system shaped by collisions, accretions, and gradual change. This tartan draws directly from those luminous, layered galactic images first captured by Hubble and the observatories that followed. 🖤 💜 🤍 💗 ❤️ 🔭✨ 🌌

Infrared light is electromagnetic radiation with wavelengths longer than those of visible light but shorter than radio waves. It is invisible to the human eye, but very useful for astronomical observations! Cold, dark molecular clouds of gas and dust in our galaxy will glow with infrared frequencies as they are irradiated by embedded stars. Infrared can also be used to detect protostars even before they begin to emit visible light! The discovery of infrared radiation is ascribed to 19th century astronomer William Herschel who used a prism to refract light from the sun and detect the infrared, referring to them as "Calorific Rays." Although it is not possible for warm-blooded animals such as mammals and birds to see infrared light because their own bodies release heat, several cold-blooded animals have evolved to see infrared light including snakes, blood-sucking insects, some fish, and some frogs! 🔭 🌌

Nowadays, clear days (and nights) are blessings! Don't you wish for the days when you had more opportunities for unobstructed views of the heavens?

A star trail is a type of photograph that uses long exposure times to capture the apparent motion of stars in the night sky due to Earth's rotation. A star-trail photograph shows individual stars as streaks across the image, with longer exposures yielding longer arcs. The Earth rotates full circle relative to the backdrop stars in a period of about 23 hours and 56 minutes.

This evocative and deeply hued tartan illustrates the long-exposure photography of stars as they appear to move across the sky, leaving colourful trails, perfect for the astrophotographer or amateur star gazer in your life. 💙 🖤 💛 🤍 ❤️ 🌌 🔭 ⭐ ⭐ ⭐

Sunspots are temporary phenomena on the Sun's photosphere that appear as visible dark freckling on the sun's surface. First noted by Chinese in 800 BC, sunspots occur as a result of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity and occur in cycles of 11 years, half of a 22 year cycle of solar activity. The magnetic activity that accompanies the sunspots can produce dramatic changes in the ultraviolet and soft X-ray emission levels and are much studied to understand the effect on the earth's climate. Sunspots sometimes erupt into powerful solar storms that shoot streams of charged particles into space, occasionally in the direction of Earth, and can bombard the Earth's magnetic field and disrupt power grids or knock out satellites in orbit! Solar Cycle 25 began in December 2019. The expected solar maximum is expected to occur between 2023 and 2026 with a sunspot range similar or slightly stronger in strength relative to cycle 24 of 95 to 130, 🌞

The 2020 Wolf Moon Penumbral Eclipse, one of 13 full moons this year, though not visible during the daylight hours in the America's, will be visible in Europe, Africa, Asia and parts of Australia! In the case of a penumbral lunar eclipse, the moon is covered by Earth’s lighter or outermost shadow (the penumbra) as opposed to its main shadow (the umbra). If you are in the right spot for viewing you will notice a dark shading on the moon’s face. 🌚

Kilted astronomers and stargazers, take note! Impress your friends with this beautifully composed tartan which has designed into the sett colourful elements of our own Milky Way galaxy!

The Milky Way, our home galaxy, is a magnificent barred spiral structure composed of nearly 300 billion stars, interwoven with interstellar dust, gas, and glowing nebulae. Nestled within one of its smaller spiral arms—the Orion Arm—our Sun is but a single point of light among countless others in this vast cosmic system.

This tartan draws visual inspiration from the Milky Way itself. The lighter bands woven through the design evoke the bright, dense starfields that trace the galactic plane, while the darker areas represent the so-called Zone of Avoidance—a region veiled by cosmic dust and stellar crowding that obscures our view.

Also threaded through this galactic motif are striking red lines, a nod to the phenomenon of cosmological redshift, the stretching of light caused by the universe's continual expansion. These vibrant streaks hint at the restless nature of the cosmos and the dynamic motion of celestial bodies.

Though it may appear still to our eyes, the Milky Way is anything but static. It is currently on a slow-motion collision course with the Andromeda galaxy, its spiral twin. But there's no need for alarm—this grand galactic merger will play out over the next 4.5 billion years, a slow cosmic dance unfolding on a scale far beyond human lifetimes. That's one very long galactic kilt flip equivalent! 💙 💜 🖤 💗 ⭐💫 🔭 🌌

If you dare to sport this tartan of shadow and substance, you may find yourself betwixt and between as we approach the long White Nights of late May and June beneath the Arctic Circle. With its deep blues, icy greys, and fading bands of light, this Arctic twilight tartan seems perfectly suited to the strange beauty of the far north during the season when the horizon never fully darkens and twilight lingers deep into the night. Here, day and night blur together beneath glowing skies, and reality itself can feel ever so slightly uncertain.

It is precisely the sort of landscape that might have appealed to the masters of mid-century television suspense.

First airing in 1959, The Twilight Zone became famous for blending science fiction, suspense, psychological drama, and the supernatural into stories where ordinary people suddenly found themselves confronting the unknown. Introduced each week by the unmistakable voice of Rod Serling, the series explored paranoia, isolation, fear, and strange reversals of reality — themes perfectly suited to the eerie atmosphere of the far north.

Near the Arctic Circle, May brings the remarkable phenomenon of sustained twilight, when darkness never fully settles and the horizon glows deep into the night. During these lingering hours, the famous “Belt of Venus” may appear — a soft pink band above the horizon visible shortly before sunrise or after sunset — creating a landscape that feels suspended somewhere between dream and reality. Twilight itself has long been regarded as a liminal hour, a threshold between worlds where certainty fades and strange possibilities emerge.

It is little wonder that this atmosphere found its way into mid-century science fiction and anthology television. While the original The Twilight Zone surprisingly featured few true polar-station stories, several episodes captured that same feeling of frozen isolation and psychological unease. Episodes such as The Midnight Sun, I Shot an Arrow into the Air, The Invaders, and The Thirty-Fathom Grave evoke barren landscapes, lonely survival, and cold existential dread.

And yet, for all the mystery and midnight unease of Arctic twilight, this tartan wears its shadows rather well. After all, some tartans are made for bright colours and dazzling daylight … and others seem destined for the twilight zone. 🖤 🤍 🖤 🧊 🧊 🧊 🐻‍❄️

There are strange happenings in the skies above if you just look!

For fortunate skywatchers and astronomers, there’s a whole constellation of tartans to explore—and even more so if your eyes are drawn to the night sky! Residents of Canada, Alaska, the UK, New Zealand, Australia, and Scandinavia may be lucky enough to witness one of Earth’s most mysterious and mesmerizing atmospheric displays: the phenomenon known as "STEVE."

First brought to widespread attention in 2016, STEVE—short for Strong Thermal Emission Velocity Enhancement—is a captivating light show that graces the heavens in a form quite unlike the familiar northern lights. Instead of the classic auroral waves, STEVE appears as a narrow, vivid ribbon of purple light arcing across the night sky. Often accompanying it are flickering vertical green bands nicknamed "picket fences," lending the spectacle an even more otherworldly appearance.

Though initially mistaken for a type of aurora, STEVE is believed to result from different atmospheric mechanisms. While typical auroras are produced when solar particles collide with molecules in Earth’s upper atmosphere, STEVE’s distinct glow is thought to stem from unusually high temperatures affecting charged particles—heated to thousands of degrees—much farther above the Earth.

So next time you look up into the night sky, remember: there’s more up there than meets the eye—sometimes even a ribbon of purple light, glowing like a tartan woven by the universe itself. 💜 💚 ❤️ 🖤 💙 🔭 💫 💫 💫

This tartan burns with the colours of this weekend's solar activity, marked by multiple sunspots, significant solar flares, and coronal mass ejections (CMEs), which have intensified auroral displays globally at unusual latitudes! A sunspot is a temporary phenomenon on the Sun's photosphere that appears as a dark spot compared to surrounding areas. These spots are cooler than the rest of the Sun's surface and are caused by intense magnetic activity, which inhibits convection by reducing the energy transported from the Sun's interior to its surface. Sunspots can be very large, often several times the size of Earth! The solar storms have created conditions for a spectacular auroral show and so far have not significantly adversely affect our electrical infrastructure! Enjoy the show for now! 🖤 💛 🤎 🧡 🌞 🔥 🔥

Or is it?

Ka-boom! Asteroid Day commemorates the morning of June 30, 1908, when a tremendous explosion occurred over the remote Tunguska region of Siberia near the Stony Tunguska River. Generally attributed to the airburst of a stony meteoroid about 100 meters (330 feet) across, the blast remains one of the largest impact events in recorded history.

Curiously, although it is classified as an impact event, no crater has ever been found. Instead, the explosion flattened more than 830 square miles (2,150 km²) of forest, leaving millions of trees lying like matchsticks.

This asteroid and moon-coloured tartan with its illuminated greys and dark shadows was designed to celebrate robotic and human exploration, along with the scientific discoveries and educational outreach associated with the Moon and other airless worlds, including asteroids, comets, Kuiper Belt Objects, and beyond.

The asteroid Vesta, named for the Roman goddess of the hearth, home, and sacred fire, is shown below. Discovered by Heinrich Wilhelm Olbers in 1807, it is one of the largest objects in the asteroid belt and is occasionally bright enough to be seen with the naked eye!

Once named exclusively after female mythological figures, asteroids are now named for an astonishing variety of people, places, scientific achievements, works of art, and fictional characters. Among them are Arthur Conan Doyle's famous creations—5048 Moriarty, 5049 Sherlock, and 5050 Doctorwatson—as well as every member of the legendary British comedy troupe, Monty Python! Nudge nudge, wink wink, say no more! 🤍 🖤 🤍 🌑 🌔 🌓 🌖 🌕 🔭 ☄️ ☄️ ☄️

Ka-boom! Be ready for cosmic destiny if we must, with a tartan commemorating the ancient wanderers of our solar system: asteroids. These rocky relics, remnants from the solar system’s violent beginnings, carry both the secrets of our origins and the potential for global catastrophe! In an age when the phrase “Don’t Look Up” has become both cultural commentary and cautionary metaphor, this tartan reminds us that sometimes, looking up is exactly what we must do—especially if we want to see what's coming.

Asteroid Day, observed each year on June 30, commemorates the cataclysmic explosion that rocked the remote Tunguska region of Siberia in 1908. On that fateful morning, a stony meteoroid estimated at around 100 meters in diameter exploded in the atmosphere in a powerful event known as an airburst. Although no impact crater was discovered, the blast was strong enough to flatten more than 830 square miles of forest. It remains the most powerful impact-related event in recorded history not caused by nuclear weapons.

In recognition of the ongoing risk posed by near-Earth objects, NASA is preparing to launch the Near-Earth Object Surveyor (NEO Surveyor)—a space telescope designed to detect and track asteroids and comets that could pose a threat to our planet. Now scheduled for launch in 2027, the NEO Surveyor will use infrared sensors to detect even dark or sunward-approaching objects, dramatically improving our planetary defense capabilities.

To mark this vital mission, a specially designed tartan has been created, woven with rich symbolism in its colors and thread count. The deep blues represent large-radius objects like the Tunguska asteroid. Black threads symbolize the telescope and its anticipated mission span. Red and dark red reference the infrared filter bandpasses used in detection, while lighter blues stand for the spacecraft’s sensitive detectors. Yellow and black threads commemorate the year 2006, when the mission proposal was first submitted. This tartan is not only a tribute to cutting-edge science, but a woven reminder of Earth's position in the larger cosmic dance! ❤️ 💙 🖤 💛 🤍 🌎 ☄️ 🛰️

The U.S. space agency is rigorously testing its Orion spacecraft in hopes of launching its first mission to the moon as early as 2019!

Did you see the televised moon walk on July 20th, 1969 by the crew of the Apollo 11? The lunar terrain, a mesmerizing and desolate landscape, is a testament to the Moon's dramatic history. Its surface, marked by vast plains known as maria, is the result of ancient volcanic activity, where molten basalt flooded and solidified into smooth, dark expanses. Craters of varying sizes, formed by countless meteorite impacts over billions of years, pockmark the highlands and lowlands alike, creating a rugged and uneven terrain. The stark contrasts between the bright, mountainous highlands and the darker, smoother maria present a striking visual. These features, combined with the fine, powdery regolith covering the surface. This tartan was created to celebrate mankind's return to the moon, from the first lunar landing by Apollo 11 which took place on 20 July 1969 until the crew of Apollo 17 set the last foot on the moon on 19 December 1972 to the newest project to return. The design was inspired by the lunar surface and the designer used the colours of lunar rock samples to select the colours for the tartan. The sett incorporates elements to represent Neil Armstrong, the first to set foot on the moon. 🚀 🌕 🌗 🌓 🌚

On July 20, 1969, viewers around the world watched on television as the Apollo 11 Lunar Module, nicknamed the Eagle, descended toward the moon’s surface. This mission marked the fulfillment of President John F. Kennedy’s 1961 pledge to land a man on the moon and return him safely to Earth before the decade’s end. The flight crew included Commander Neil Armstrong, Lunar Module Pilot Edwin “Buzz” Aldrin, and Command Module Pilot Michael Collins. While Armstrong and Aldrin descended to the moon's surface in the Eagle, Collins remained in lunar orbit aboard the Command Module, Columbia, for over 21 hours. The entire crew returned safely to Earth on July 24, 1969.

Designed to celebrate this achievement, the Apollo 11 tartan honors the historic spaceflight and the first moon landing, as well as the pioneering spirit of Armstrong and Aldrin—the first humans to walk on the moon. Fifty years later, the legacy continues with NASA’s ongoing pursuit of exploration and discovery.

Although Commander Armstrong referred to his first step on the moon as “small,” it was actually a leap of 3.5 feet. The landing plan was to cut the Eagle’s engines when it hovered a few feet above the surface. NASA engineers had built the Eagle with legs designed to compress on landing and act as shock absorbers. However, Armstrong’s exceptionally smooth touchdown meant the legs didn’t compress. As a result, the astronauts had to exit from a greater height than expected. That “small step” was, in fact, a hop of 3.5 feet from the Eagle’s ladder to the lunar surface.

One thing we do know, the tartan is verifiable. Wink, wink! ❤️ 🤍 💙 🖤 🌔 🌔 🌔 👨‍🚀 👨‍🚀 👨‍🚀

This favorite children’s tune about the night sky is now often sung to the French melody Ah! vous dirai-je, maman, first published in 1761 and later arranged by several composers—including Mozart, who wrote twelve delightful variations on it.

Star gazers know that “twinkling,” or scintillation, happens because distant stars appear as tiny points of light, easily disturbed by Earth’s restless atmosphere. Turbulence high above can act like a lens or prism, bending and diverting the light’s path, creating that magical sparkle.

August is a fine month for stargazing. As the sweltering Dog Days of summer draw to a close, the Perseid meteor showers arrive—one of the year’s most anticipated celestial displays. Associated with the comet Swift–Tuttle, these “shooting stars” seem to stream from the constellation Perseus and will peak this year on August 11th, 12th, and 13th.

When a meteor enters our atmosphere, its fiery trail tells a colorful story. Different elements within the meteor emit different hues as they burn: iron glows bright yellow, silicates blush red, and copper creates that unmistakable green flash often seen in the trails of brighter meteors.

This dark-sky tartan captures that wonder, with shimmering streaks of color against a soft night glow—perfect for kilted star gazers of all ages. And of course, when you see that first twinkle in the evening sky or a bright streak across the heavens… don’t forget to make a wish. 🖤 💙 ❤️ 💛 ⭐⭐ ⭐ 🌠 🌠 🌠 🔭

Were you in the path of the totality in 2017 for "The Great American Solar Eclipse"? Ready for the next one? The next Great North American Eclipse will take place at the Moon's ascending node on Monday, April 8, 2024. The Moon's apparent diameter will be larger than usual, and with a magnitude of 1.0566, its longest duration of totality will be of four minutes and 28.13 seconds near the town of Nazas, Durango, Mexico and the nearby city of Torreón, Coahuila. This eclipse will be the first total solar eclipse to be visible in Canada since February 26, 1979, the first in Mexico since July 11, 1991, and the first in the U.S. since August 21, 2017. It will be the only total solar eclipse in the 21st century where totality will be visible in the three-state set of Mexico, the United States, and Canada! The eclipse will be partially seen in Svalbard (Norway), in Iceland, Ireland, west parts of Great Britain, north-west parts of Spain and Portugal, the Azores and Canary Islands. Totality will pass through the town of Wapakoneta, Ohio, home of Neil Armstrong, the first person to set foot upon the Moon. 🌖 🌘 🌚 🌑

As if another dark portent is called for this year ... tonight brings us a Black Moon (a Third New Moon in a season with four New Moons).

For the blackest of nights, we have the blackest of black tartans with a visible sett highlighted only by differing light reflecting qualities of the all black stitches (the picture below uses a lighter color for illustration only).

While the term "Blue Moon" (astronomically speaking) generally refers to the second full moon in a calendar month, occurring at the same frequency is a "Black Moon," or "Dark Moon," the second new moon in a month (or by another definition: no new moon in a month; or even the third new moon in a season of four new moons)!

n Celtic traditions, the dark or new moon was regarded as a liminal time, well-suited for banishing evil, binding protection, or setting intentions, and Druids often aligned their rites with unusual celestial events, treating them as thresholds between the ordinary and the uncanny. This sense of charged stillness carried into early modern witchcraft lore, where the “dark moon” phase—the brief span of nights when no lunar light is visible—was considered the most potent for banishment spells, protective wards, and, at times, curses. In contemporary astrology, the Black Moon continues this lineage of mystery and power, viewed as an intensified form of new moon energy, a period associated with endings, shadow work, and shielding against hidden dangers.

Considering everything, enlist the ancient superstition of crossing your fingers! Just in case. 🖤 🖤 🖤 🌑 🤞

This rare full Blue Hallowe'en Hunter Super Moon is the first to be able to be seen round the globe since 1944! There are two types of blue moons commonly reckoned - the third of four full moons in a season; or a second full moon in a month of the common calendar. Today's moon is of the second type. This rare moon is also called the Hunter's Moon, Travel Moon, Dying Grass Moon, Blood Moon or Sanguine Moon, most of which refer to the hunting season. In the Celtic calendar, this moon is known as the Reed Moon.

Although the saying "once in a blue moon," (a phrase which 400 years ago meant something absurd) has changed its meaning over time to indicate a rare or improbable occurrence, it never referred to the actual colour of the moon which normally tends toward warmer end of the colour spectrum. However, the rare blue moon has appeared bluish, such as in 1883 after the volcano Krakatoa erupted, causing dust in the atmosphere to act as a colour filter, causing sunsets and the moon to turn green and blue all over the world. Happy Blue Moon Hallowe'en! 🎃 🌔 💙

On September 1, 1859, British astronomer Richard Carrington was sketching a massive sunspot when he witnessed something extraordinary—a sudden flash of brilliant white light erupting from the Sun’s surface. Unbeknownst to him, he had just become the first person to observe a Coronal Mass Ejection, or CME, with his own eyes. And this one was on a direct collision course with Earth!

Seventeen hours later, the skies above North America blazed as if dawn had come early. The Aurora Borealis, usually confined to the polar regions, shimmered as far south as Colombia. In the Southern Hemisphere, the Aurora Australis flared beyond Brisbane. By September 2, the most powerful solar storm ever recorded smashed into Earth’s magnetic field!

The impact was unlike anything people had ever seen. Telegraph systems across continents crackled with surging currents. Operators reported electric shocks, paper bursts into flame, and wires continued transmitting even when cut off from their power supplies—driven solely by the storm’s geomagnetic force! The event would forever bear Carrington’s name.

Today, scientists know such storms are not unique. A Carrington-scale event striking now would endanger satellites, GPS navigation, communication systems, and entire electrical grids. Space weather monitoring stations—like NASA’s Solar Dynamics Observatory and NOAA’s Space Weather Prediction Center—constantly watch the Sun for solar flares and CMEs, issuing warnings when magnetic storms are likely to reach Earth. Despite these safeguards, our technological society remains deeply vulnerable to another storm of Carrington’s magnitude.

This year we are at the peak of activity in Solar Cycle 25, the Sun’s current ~11-year cycle. Solar maximum—when sunspots, flares, and coronal mass ejections (CMEs) are most frequent—is unfolding right now. Already, the Sun has unleashed multiple powerful X-class flares and strong CMEs, with some of the most intense space weather storms since 2003 appearing in 2024 and continuing into 2025. Scientists expect this elevated activity to last for at least another year or two before gradually declining toward the next solar minimum. Yikes! 🧡 🖤 ❤️ 😎 🔥 🔥 🔥

The night sky beckons! In Scottish folklore, the Northern Lights are known as Na Fir Chlis—“the Nimble Men” or “the Merry Dancers”—a poetic name for the shimmering waves of light that seem to dance across the heavens, created when energetic particles from the sun collide with the Earth’s magnetic fields near the poles.

The term aurora borealis was introduced in 1619 by Italian astronomer Galileo Galilei, who combined Aurora, the Roman goddess of dawn, with Boreas, the Greek god of the north wind. Yet long before Galileo, storytellers spun their own interpretations. Some spoke of celestial battles, with the aurora glowing as the sign of warriors clashing in the skies or angels cast down to Earth. One Hebridean legend even tells of blood from the wounded staining stones below, giving rise to the “bloodstones”—a striking jasper still found in the islands.

Across cultures, the aurora has inspired vivid imagery. The North American Inuit call it aqsarniit, or “football players,” imagining spirits of the dead tossing a walrus head across the sky. The Vikings believed the glowing lights reflected from the armor of the Valkyrie, the supernatural maidens who carried warriors to the afterlife.

Today, the aurora watching season stretches from August through April in northern polar regions—Alaska, Canada, Scotland, Greenland, Iceland, Scandinavia, and Siberia—with peak displays often in September and March. Just as these luminous ribbons shift from blue and green to violet and crimson, this tartan captures the brilliant variety of colors woven into the aurora’s dance.

Seek and ye shall find! The Fermi paradox—named after Italian-American physicist Enrico Fermi—captures the great riddle of our age: if the universe is so vast, and the odds so favorable, where is everyone? The Drake Equation frames the puzzle in numbers: stars forming, planets circling, Earth-like worlds arising, some of which may host life, intelligence, and communication. Factor in the lifespans of civilizations, and the equation suggests a galaxy alive with neighbors. Are they out there? Hidden? Obscured?

Designed for Charles Cockell, Professor of Astrobiology at Edinburgh University, this tartan captures this paradox in pattern and color. Black speaks for the void of space; blue squares, the rare oases of water where life might root itself; and green, the fragile filaments of biology stretching across the cosmos, converging in three lines for our own Earth—the third planet from the Sun. Red evokes Mars, poised on the edge of habitability; yellow, our Sun, the single star we know to sustain life; and white, the starlight that would greet the eyes of any being gazing upward from another world.

This September 2025, NASA’s Perseverance rover uncovered intriguing patterns in a rock nicknamed Cheyava Falls (from the “Sapphire Canyon” outcrop) in Jezero Crater, a site that once held an ancient lake. The sample contained organic carbon and unusual mineral textures resembling those produced by microbes on Earth. While natural chemistry could also explain the findings, the discovery stands as one of the tantalizing signs so far that Mars may once have hosted life!

And so the search continues and the mystery deepens! 🖤 ❤️ 💙💚 💛 🪐 🪐 🪐 🧬 🧬 🧬

The Harvest Moon, rising nearest the autumnal equinox, has long carried many names—Corn Moon, Barley Moon, Gypsy Moon, Singing Moon—each connected to the rhythm of the seasons and the work of gathering crops. For people in the Celtic Isles it was more than just extra light for farmers; it marked the tipping point of the year as the dark season approached. In the Highlands, stories told of spirits moving more freely under its bright watch, while fishermen along the western isles believed the Harvest Moon calmed the seas and drew fish closer to shore.

This moon always looks larger and richer in color than others, glowing copper or amber in the autumn sky. Part of that is the “Moon Illusion,” the old puzzle of why the Moon sometimes seems so big on the horizon. In times past, people explained this phenomenon as giants pulling it closer, or faery hands tugging it down to light the fields and hedgerows!

In Orkney, there was a belief that the Harvest Moon could slip into dreams. To sleep under its light was to invite messages from the otherworld! And in Ireland, people sometimes called it the Singing Moon, the time when neighbors gathered for music and story before winter closed in. However it was named, the Harvest Moon was always a gift—giving farmers more hours to work and hopefully, to enjoy a bountiful harvest.

Shine on, Harvest Moon! 💙 💛 🤍 🖤 🌕 🌕 🌕 🌾

“Indian summer” is the name long given to that golden and warm period which reappears between the first frost and true winter—an unseasonably warm spell that returns just when winter seems ready to settle in. The term originated in 18th-century North America, describing those still, hazy days of late autumn. Its exact origins are as elusive, though some believe early settlers borrowed the phrase from Native Americans, who used the lingering warmth to finish their harvest. In certain Native stories, this warm reprieve is said to come from the sighs of the southern wind, soft and generous before its long sleep.

Across Europe, these gentle days go by many other names: Old Wives’ Summer, All-Hallows Summer, Gypsy Summer, Little Summer, Badger Summer, or Quince Summer. Elsewhere, they align with saints’ feast days, becoming St. Martin’s Summer or St. Luke’s Summer.

In Ireland, the season is affectionately known as fómhar beag na ngéanna—“the little autumn of the geese.” And in Britain, the old phrase Goose Summer evolved into th word "gossamer", symbolizing the way sunlight illuminates the delicate strands of spider silk which float in the last warm breaths of the season. 💛 🤎 🧡 💛 ☀️ 🕸️

The transit or passage of a planet across the disk of the Sun may be thought of as a special kind of eclipse. As seen from Earth, only transits of the inner planets Mercury and Venus are possible. Planetary transits are even more rare than eclipses of the Sun by the Moon. On the average, there are 13 transits of Mercury each century. In comparison, transits of Venus usually occur in pairs with eight years separating the two events. However, more than a century elapses between each transit pair. The first transit ever observed was of the planet Mercury in 1631 by the French astronomer Gassendi. The next observable planetary transit will take place this day in 2032, when Mercury will travel across the disk of the sun, casting its shadow. This tartan was designed by Arpin Pierre for the last transit of Venus which occurred in June 2012, with colors and geometry marking the dark shadow cast across the fiery yellow and red disk of the sun against the dark blue sky. The companion picture shows Mercury's Caloris basin, the largest impact basin on the planet. ☀️ 🌑 🔭

It’s never too early—or too late—to kilt up and look skyward. Whether you’re a seasoned stargazer or a curious newcomer, the heavens are always ready to dazzle. And while this editor may not make it to Halley’s Comet’s next scheduled return in summer 2061, there’s no shortage of stellar spectacles to enjoy in the meantime. Halley’s Comet, one of the most famous periodic comets, last appeared in 1986 and is responsible for two annual meteor showers—the Eta Aquariids in May and the Orionids in October. So in a way, it’s still with us, streaking across the night sky in the form of glowing trails.

The tartan featured here reflects the shimmering beauty of comets in motion: deep midnight blues and glacial greens evoke the ion and dust tails streaming across a dark sky, sculpted by solar winds and sunlight. It’s a visual echo of nature’s finest pyrotechnics—silent, mysterious, and breathtaking.

A recent standout was Comet NEOWISE, discovered in March 2020 during NASA’s NEOWISE mission. By July of that year, it was visible without a telescope, painting luminous arcs across the northern hemisphere and drawing comparisons to the legendary Hale–Bopp. Photographer Anthony Murphy captured its glow above the ancient site of Newgrange in Ireland—a once-in-a-lifetime image for a once-in-6,800-year event.

Here's a list of the most spectacular historic comets and their next return dates!

🔁 Halley's Comet – Last seen 1986, returns 2061
💥 Hale–Bopp – Blazed across skies in 1997, returns ~4385 AD
✨ NEOWISE – 2020 pandemic comet, returns ~8786 AD
🌠 Hyakutake – Stunning close pass in 1996, returns in ~18,000 years
🔄 Encke’s Comet – Shortest orbit (~3.3 years), next in 2027
🌌 Swift–Tuttle – Source of the Perseids, returns 2126

Orion is one of the most well-known constellations, easily recognized by its belt of three stars. It features Betelgeuse and Rigel, two of the brightest stars in the night sky, and contains the Orion Nebula, or M42. This nebula, a young open star cluster and active star-forming region, is visible to the naked eye on a clear, dark night without moonlight. The Orion Nebula is located about 1,350 light-years from Earth and spans approximately 24 light-years across. It is one of the closest regions of massive star formation to our planet, making it a key area of study for astronomers. The nebula is part of the Orion Molecular Cloud Complex, a vast area of gas and dust that includes other notable features like the Horsehead Nebula. Within the Orion Nebula, scientists have observed a cluster of newly formed stars called the Trapezium, whose intense ultraviolet radiation illuminates and shapes the surrounding clouds. Additionally, the nebula contains protoplanetary disks, or "proplyds," which are the building blocks of potential planetary systems. The first recorded observation of the nebula’s diffuse, cloudy nature was made on November 26, 1610, by French astronomer Nicolas-Claude Fabri de Peiresc using a refracting telescope provided by his patron, Guillaume du Vair. Today, the Orion Nebula continues to be a focal point for research, offering insights into the processes of star and planet formation. The colours represented are: purple for the dominant colour of the nebula; green for the colour emitted by minor components of the nebula; red for the colour emitted by hydrogen atoms when excited by background radiation; blue for the main colour of M43, an adjacent nebula; and yellow for the stars forming the trapezium in the nebula core.💜 💚 ❤️ 💙 💛 ⭐ ⭐ ⭐ 🔭 ✨

Do you have a favourite Martian? Someday, it might be you! Named by the Romans after their god of war, Mars gets its bloody red-rust color from the iron-rich minerals in its loose dust and rock covering its surface. Red Planet Day commemorates the 1964 launch of the Mariner 4, NASA and Jet Propulsion Laboratory's robotic interplanetary probe. The Mariner 4 became the first spacecraft to successfully fly by Mars and send back the first close-up images of Mars. The search for evidence of life on Mars began in the 19th century and continues today. But some have even greater ambitions. SpaceX has as its key mission plans for a manned mission to Mars by 2029, with plans for both terraforming and long term colonization! This tartan's colours represent Mars' past, present, and future: red for the surface of Mars; blue for its water-rich past and its presence of water, mainly as ice, on the planet today; 4 green lines representing its position in the solar system as the fourth planet and for the presence of habitable conditions and possible future presence of life in the form of human settlement; and white forthe Martian poles, visible from the Earth, a conspicuous and important feature of the planet and its long-term climatic cycles. 🚀 🔭 👾

Over the years, NASA (National Aeronautics and Space Administration) has sent five robotic vehicles, called rovers, to Mars: Sojourner, Spirit and Opportunity, Curiosity, and Perseverance. Today, February 18th, after a journey of 100 days and 286 million miles, "Percy" (the nickname for Perseverance) is due to land near an ancient lake bed called Jezero Crater at 3:55 pm ET. Because it takes 11 minutes for signals from Perseverance to travel to Earth, nobody will know what's happened until about 4:06 pm. First, the capsule carrying Perseverance has to enter through the Martian atmosphere at 12,000 mph, which superheats the material around it to up to 2,370 degrees Fahrenheit. Then it must deploy a 70-foot-wide parachute, slowing its fall to about 150 mph, and drop its heat shield. This will expose the rover's underside, giving it an open view of the ground below and allowing an onboard navigation system to identify the best landing spot. About a mile above the Martian surface, the capsule must drop the rover, which is equipped with a jetpack on its back. The jetpack's engines should fire up and fly Perseverance to its landing spot. Once there, the jetpack must slowly lower the rover on 25-foot-long nylon cords until its wheels touch the ground. If Perseverance lands successfully, it will spend its first few weeks on Mars checking all its systems and pinpointing any issues so that engineers on Earth can troubleshoot. Then the rover will open its belly panels to release a small drone called Ingenuity. The little helicopter is set to attempt the first-ever rotocraft flights on another planet. Then the rover will set out on its hunt for alien fossils in the cliffs and sandy plateaus of Jezero Crater. 🪐 🚀

Black Hole Friday, an informal term for the Friday following Thanksgiving in the United States, has been cleverly repurposed by astronomers and science educators to spotlight the fascinating study of black holes! The concept of a body so massive that even light couldn’t escape dates back to November 1784, when English clergyman and astronomical pioneer John Michell proposed the idea in a letter. Later, Albert Einstein predicted the existence of black holes in 1916 through his general theory of relativity, though the term “black hole” wasn’t coined until 1967 by American astronomer John Wheeler.

After decades of theoretical exploration, the first physical black hole was discovered in 1971. Black holes vary greatly in size, ranging from miniature to colossal, with the supermassive black holes reigning as the universe’s giants—some boasting masses billions of times that of our sun! In our Milky Way galaxy alone, scientists estimate there are about 100 million stellar-mass black holes, along with the supermassive Sagittarius A* (Sgr A*) at its core, containing the mass of roughly 4 million suns.

In a recent breakthrough in 2020, astronomers using the NASA/ESA Hubble Space Telescope observed dramatic dark and light rays emanating from the bright center of IC 5063, an active galaxy 156 million light-years away in the constellation Indus. Researchers believe a torus-shaped ring of dusty material surrounding IC 5063’s central black hole is casting an extraordinary X-shaped shadow into space. The mysteries of black holes continue to inspire wonder and exploration! 🖤 💜 💙 ❤️ 💛 🤍 🖤 ☀️ ⚫ 🔭

Over many centuries, this full moon has been called several names: Cold Moon, Dark Night Moon, Birch Moon, or Bitter Moon. Native American tribes also named these winter moons the Drift Clearing Moon (Cree), Frost Exploding Trees Moon (Cree), Moon of the Popping Trees (Oglala), Hoar Frost Moon (Cree), Snow Moon (Haida, Cherokee), and Winter Maker Moon (Western Abenaki).

It will be 2029 before another Cold Moon occurs this close to the winter solstice. 🌔

Today marks the longest night and the shortest day of the Northern Hemisphere, long viewed by ancient cultures as a time of death and rebirth. The actual date of the winter solstice varies from year to year, and can fall anywhere between December 20 and December 23, with the 21st or 22nd being the most common. The term 'solstice' derives from the Latin word 'solstitium', meaning 'Sun standing still'. On this day the Sun seems to stand still at the Tropic of Capricorn and then reverses its direction as it reaches its southernmost position as seen from the Earth. Stonehenge, the prehistoric monument located in Wiltshire (c. 2500 BCE) , is carefully aligned on a sight-line that points to the winter solstice sunset (opposed to New Grange, which points to the winter solstice sunrise, and the Goseck circle, which is aligned to both the sunset and sunrise). The only other megalithic monuments in the British Isles which clearly align with the sun are Newgrange in County Meath, Ireland and Maeshowe situated on Mainland, Orkney, Scotland. Both famously face the winter solstice sunrise. Today modern astronomers, such as those at The Scottish Dark Sky Observatory near Loch Doon, East Ayrshire, with its low levels of light pollution and clear horizon views, contemplate the mysteries of the universe year round. 🔭🌌

Considered one of the most influential environmental and inspirational photographs ever taken, this photo was taken from the lunar orbit of the Apollo 8 by astronaut William Anders on the 24th of December 1968, and was only made possible by a collaborative effort by all three NASA crew members. 🌍
