Stanford researchers suggest water may be common within Europa’s ice shell

TL;DR

Europa, one of Jupiter's moons, has a rocky interior surrounded by a global ocean and an ice shell. Its unique surface features provide insight into the moon's interior and potential for habitability.

Transcript

• Europa is one of Jupiter's moons. It's kind of about the same size as our own moon but a really different structure. It has this rocky interior, but it's surrounded by this global ocean. And on top of that ocean, we've got this ice shell that's maybe as much as 20 to 30 kilometers thick. The heat and chemical signatures that are there suggest it ... Read More
