What is a Vol­canic Erup­tion Like in Space?

Can vol­canic erup­tions take place on other plan­ets? And are they like those on Earth?

Science Illustrated - - ASK US -

Vol­canic erup­tions are very com­mon on other heav­enly bod­ies and can take place just like on Earth.

When volcanoes on Mars, Venus, and prob­a­bly also on Mer­cury erupt, molten rock, gas, and ash flow out of a crater to pro­duce a cone-shaped “bump” just like on Earth. On Jupiter’s Io moon, the volcanoes also emit molten rock, but on the small moon, stan­dard grav­ity is so slight that the col­umn of mass could rise hun­dreds of kilo­me­tres above the sur­face.

The So­lar Sys­tem also in­cludes cold volcanoes (cry­o­vol­ca­noes), which emit liq­uids such as am­mo­nia, wa­ter, or meth­ane. The most re­li­able in­di­ca­tions of cold volcanoes have been found on Saturn’s Ti­tan moon. Ac­cord­ing to sci­en­tists, Jupiter’s Europa and Ganymede moons, Saturn’s Ence­ladus moon, and Uranus’ Mi­randa moon in­clude cry­o­vol­ca­noes.

Cry­o­vol­ca­noes ex­ist on ice moons in the So­lar Sys­tem. They emit cold ma­te­ri­als such as am­mo­nia and wa­ter.
