The chemicals necessary for the formation of life have been detected in lab-grown comet ice -- a discovery that could have huge implications for discovering how life as we know it was spawned.
The European Space Agency is giving up on trying to contact the lost Philae comet lander, which had an unexpectedly rough touchdown after its release 16 months ago from the orbiting Rosetta mothership.
Gravity measurements taken by the orbiting Rosetta spacecraft show the body of comet 67 P/Churyumov-Gerasimenko is about 75 percent dust and 25 percent ice all the way through.
On a January morning 10 years ago, tiny pieces of a comet landed on Earth inside of a spacecraft -- and these samples are still teaching us new things about the origins and evolution of our solar system.
A European spacecraft has spotted water ice on the surface of a comet, shedding new light on the formation and evolution of the icy object.
The odds aren’t great. Engineers don’t even know if Philae still has a working receiver and the probe could be covered in dust.
An infrared NASA space telescope has been keeping tabs on dozens of comets and has revealed huge quantities of carbon monoxide and dioxide being vented into interplanetary space.
Europe's Rosetta mission has found that Comet 67P/Churyumov-Gerasimenko is spewing molecular oxygen into space -- why would this be a bad thing for the hunt for extraterrestrial life?
