Scientists uncovered new insights regarding the potential role of comets, particularly Comet 67P/Churyumov-Gerasimenko, in delivering water to early Earth. A new study led by Kathleen Mandt, a planetary scientist at NASA's Goddard Space Flight Center, has renewed focus on the role of Jupiter-fa...
Comets: individual (67P/Churyumov-Gerasimenko)Rosetta has detected water ice existing on the surface of Comet 67P/Churyumov-Gerasimenko in various types of features. One of particular interest is the frost-like layer observed at the edge of receding shadows during the whole mission, interpreted...
"So the theory of comets delivering water was reappearing, but this time it was said that Kuiper Belt comets could have brought the water," Altwegg said. "Now with our new comet, 67P/Churyumov-Gerasimenko, where we can measure with Rosetta, we have a second Kuiper Belt comet and we w...
Like all comets, 67P/Churyumov-Gerasimenko is a frozen remnant of the primordial material used to form the sun and planets 4.6 billion years ago. Comets may have delivered water to Earth and along with it, organic compounds that may have played a role in the development of life. ...

We perform numerical simulations to show that the ambient dust coma is driven by pervasive but non-uniform water outgassing from the homogeneous surface layer. Physical collimations of gas and dust flows occur at local maxima of insolation and also via topographic focusing. Coma structures are ...
