Scientists are particularly fascinated by Jupiter's moon Europa and its ice shell because they believe that the ocean hidden under that ice may be one of the most likely places to find extraterrestrial life in our solar system. Imagine your surprise when scientists studying the distant moon saw something that looked very much like the past of our home planet: all that ice moves, just as it did here on Earth about 580 million years ago, during a period known as "Snowball". "
That's according to a new article published in the journal Nature Astronomy that builds a model of what might be happening on the moon." The scientists behind the document are working in the context of what we know. about Europe-things like the amount of sunlight that reaches its surface – with what we have yet to decipher – things like the amount of heat that is produced within the planet as it is pulled from its core and crushed by the enormous gravity of Jupiter.
