Here's What A Comet Looks Like Up Close

by
After 10 years in space, Rosetta made a major breakthrough this week.

A comet 250 million miles from Earth is clear as day thanks to amazing technology from the European Space Agency sending back photos.

The Rosetta spacecraft has tailed Comet 67P/Churyumov-Gerasimenko for a decade. This week, Rosetta became "the first spacecraft to rendezvous with a comet, opening a new chapter in solar system exploration," ESA says. 

Thanks to Rosetta, we don't have to marvel at comets from the ground. We can see what they look like up close. 

"Comets are considered to be primitive building blocks of the solar system and may have helped to 'seed' Earth with water, perhaps even the ingredients for life," according to ESA. "But many fundamental questions about these enigmatic objects remain, and through a comprehensive, in situ study of the comet, Rosetta aims to unlock the secrets within."
