The biggest sunspot region in more than two decades produced many impressive solar flares. Just before it disappeared, it also gave us this beautiful display of coronal loops.
The Hubble Space Telescope has picked up the faint, ghostly glow of stars ejected from ancient galaxies that were gravitationally ripped apart several billion years ago.
Favorite photos of the beautiful partial solar eclipse on October 23. 2014. Thank you to all who submitted to EarthSky.org or posted at EarthSky Facebook or G+.
