Europa may have lots of things that scientists may not know and it may have a rocky surface to.
The scientists think that Europa can have the life on it.
Scientists think there may be liquid water on Europa that we could live off of.
They think that life might exist on Europa because they have found evidence of liquid water on Europa. Hope this helps. :) <3
Scientists believe that there is liquid water, under the crust of Europa.
Europa is covered with ice and underneath a layer of ice there is an ocean that scientists think might have life living in it. Also Europa has many cracks on it.
Europa shows signs of having a saline environment, which could be amenable to life.
I have read somewhere that scientists think that europa may have an underground ocean.
no they dont
Why do astronomers think there could be life on Europa?
This is @kanimalo correcting the answer... its actually D) water ocean and tidal energy
Europa probably contains a metallic iron core. Little information about its deep internal structure is known, but this is what scientists think.
As far was we know the development requires water in its liquid for to be present and a source of energy to supply/drive chemical reactions. We know that deep down Europa has a liquid layer (of water) and the geysers of this water into space proves that there is energy in Europa's core.
