Some solar storms can bombard Earth's magnetic field and disrupt power grids or knock out satellites in orbit!

Serpens Cloud Core

Astronomy Day (Spring)
May 18

According to our best available estimates, stars having about 90 percent of the sun's mass are just now starting to die in the globulars. These stars are most probably around 15 billion years old, but they could conceivably be as young as 12 billion years or as old as 18 billion years.

Star trails

Astronomy Day (Spring)
May 18

Photography by Lincoln Harrison - There are two methods popular with star photographers – using one very long exposure (long enough to register some noticeable star movement; at least 30 minutes) OR taking many shorter exposures and stacking those images in a way that shows sequential movement.

Sunspots

Astronomy Day (Spring)
May 18

Sunspots tend to appear in cycles of 11 years and can sometimes erupt into powerful solar storms that shoot streams of charged particles into space, occasionally in the direction of Earth. Some solar storms can bombard Earth's magnetic field and disrupt power grids or knock out satellites in orbit!

Comet Day (2061)
Jul 28

As a comet gets closer to the Sun, some of its frozen gases sublimate creating a coma – a bright envelope of atmosphere that surrounds a comet. These gases can reflect sunlight which is visible in the form of two tails. The ion tail – a collection of charged particles pushed away by the solar wind – will begin to glow with a blue tint.

Mars Exploration

Red Planet Day
Nov 28

The first attempt by the United States to land on Mars was originally planned for July 4, 1976, the United States Bicentennial, but imaging of the primary landing site showed it was too rough for a safe landing.
