Lunar Eclipse (2026)
"Thy shadow, Earth, from Pole to Central Sea,
Now steals along upon the Moon’s meek shine
In even monochrome and curving line
Of imperturbable serenity.
How shall I link such sun-cast symmetry
With the torn troubled form I know as thine,
That profile, placid as a brow divine,
With continents of moil and misery?
~ At a Lunar Eclipse, Thomas Hardy (1840 –1928)
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.” 🖤 🤍 ❤️ 🪱 🪱 🪱 🌘 🌑 🌒
The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object.
Lunar eclipses occur when the Moon passes through the shadow of the Earth. They only occur during a full moon when the Earth is between the moon and the sun. There can be total, partial, and penumbral lunar eclipses.
Similarly, solar eclipses occur when the Earth passes through the Moon's shadow.
This umbra illusion tartan created by designer Carol A.L. Martin, uses amongst other shades of black, white, and grey, a particular shade called "eclipse."
In August 2008, the Full Moon slid across the northern edge of the umbra. Entertaining moon watchers throughout Earth's eastern hemisphere, the lunar passage created a deep but partial lunar eclipse. This composite image above uses successive pictures recorded during the eclipse from Athens, Greece to trace out a large part of the umbra's curved edge. The result nicely illustrates the relative size of the umbra's cross section at the distance of the Moon, as well as the Moon's path through the Earth's shadow.
