For millennia, people have seen comets come and go from afar, watching the mysterious, bright objects suddenly appear in the sky with long, spectacular tails. Now the Rosetta mission has provided an unprecedented close-up perspective. The spacecraft’s images of comet 67P/Guryumov-Gerasimenko’s surface reveal a rugged environment, covered with jagged rock and sharp cliffs. Now its lander, Philae, has snapped the first-ever photos from the surface of a comet.
