Leave it to Colin Legg – one of the most amazing sky photographers we know – to catch a meteor shower from the window seat of an airplane. Colin wrote to EarthSky:
Valentines day (night), red eye flight back to Perth.
Amazingly, the Alpha Centaurid meteor shower was active!
Fermilab’s Dark Energy Camera took a break from studying one of the greatest mysteries in modern cosmology – dark energy – to capture this stunning view of Comet Lovejoy – an extremely photogenic comet – on December 27, 2014. At the time this image was taken, the comet was passing about 51 million miles from Earth – a short distance for the Dark Energy Camera, which is sensitive to light up to 8 billion light-years away.
Two photographers – Mike Taylor and Sonia MacNeil of Mike Taylor Photo – caught a bright meteor, or fireball, from an icy beach.
When you look at the sky at this time of year, one of the most prominent constellations you see is Orion the Hunter. It’s recognizable mainly for the short, straight row of three medium-bright “Belt” stars at its mid-section. See those stars on the photo above? What you don’t see, with the eye alone, is the great complex of bright and dark nebulae – vast clouds drifting in our Milky Way – in and around Orion. That’s what Max Corneau has captured in this long-exposure photograph.
These lens-shaped clouds are often mistaken for UFOs. Here’s how they form, plus gorgeous photos and a video.

It was fiercely cold in the U.S. state of Michigan this past weekend, when Joshua Nowicki posted this cool photo at EarthSky Facebook. He said these interesting formations were created by the wind eroding the frozen sand at Silver Beach County Park in Saint Joseph, Michigan on February 14, 2015.
The MESSENGER spacecraft acquired this image of Mercury on January 23, 2015, at a time when this part of Mercury was near sunset. It’s one of the highest-resolution images yet obtained of Mercury.
