Asteroids, comets, and clouds contain complex organic molecules that form in space and might have kickstarted life on Earth ...

And for those of you wondering what all the excitement is about (and who are now perhaps intrigued by this adorable duo), welcome to the story about Rosetta. The mission’s goal is to look at the ...

After intercepting the speeding comet, a wealth of findings. The photo recently released by ESA and taken by OSIRIS wide-angle camera on the Rosetta space probe, Nov. 22, 2014. ESA/Rosetta/OSIRIS/AP ...

New research indicates that the water on Comet 67P/Churyumov–Gerasimenko has a molecular signature closely matching that of water found in Earth's oceans. This discovery revives the possibility that ...

A reanalysis of the data from the "rubber-ducky" comet 67P, collected nearly a decade ago, suggests comets may have deposited a lot more water on Earth than scientists previously thought. When you ...

Astronomers say that there are possible signs of life on Comet 67P, based on data from the European Space Agency's Philae Lander. The comet has features that indicate it may be home to alien life, ...

The intricate dance between Comet 67P/Churyumov-Gerasimenko and the solar wind is a cornerstone of contemporary space plasma research. Variations in solar wind conditions and the comet's variable ...

Hale-Bopp originated in the Oort Cloud, a theoretical shell of icy planetesimals surrounding the sun in the outer reaches of ...

Comets, it turns out, are rather more active places than we thought. Scientists poring over photos by Rosetta and Philae have unearthed evidence of a spectacular landslide on 67P -- and we caught it ...
