Water ice exists abundantly in the universe, on the surfaces of planets and moons, in comets and also in and on dust particles [1], [2], [3], [4], [5]. In protoplanetary disks, water ice can exist in the outer regions [6], where temperatures are low enough for water vapor to ...

2 of 2 Earth relative in size to the MoonEarth (left) and the Moon shown to scale. In addition to its nearness toEarth, the Moon is relatively massive compared with the planet—the ratio of their masses is much larger than those of other natural satellites to the planets that they orbit...
There are several different types of surface feature, including rocks (found on most planets and moons), and planet-specific features such as the Vall cryovolcanoes or the Wrinkle Ridges on Moho. Surface Features by Planet Kerbin Baobab Tree ...
“In terms of what you expect to see with an active mantle plume, Elysium Planitia is checking all the right boxes,” Broquet said, adding that the finding poses a challenge for models used by planetary scientists to study the thermal evolution of planets. “This mantle plume has affect...
