Comets

Earth can only hold so many photography subjects – but the universe is basically infinite, and so is its beauty. The Astrophotography Prize is a relatively new international competition that celebrates this art, and this year’s winners have been unveiled.

On February 14th, NASA's Stardust probe made its second visit to the comet Tempel 1 allowing them to compare data from the first visit and ring changes in order to learn more about comets.
