What do scientists believe that europa may have?
I have read somewhere that scientists think that europa may have an underground ocean.
Europa is the fourth largest moon of Jupiter. Scientists think that life may exist on Europa because there is evidence that liquid water may exist beneath its icy surface. Europa is pushed and pulled by the high gravity of Jupiter as well as by the gravity of Jupiter's other moons. This makes Europa expand and contract and causes it to heat up and this heat may cause some of Euorpa's icy crust to melt under…
As the Jovian moon Europa has a magnetic field, it is thought that it has a salty, liquid, 100Km deep water ocean (under a layer of ice) and a metallic iron core. Scientists are considering the possibility that this water ocean may contain some form of life. They are already conceptually designing and even engineering technology that would be able to pass through the ice and explore those theorized depths.
Most scientists would agree that life on earth did in fact originate on earth. Some scientists may believe that life on earth originated elsewhere in the universe, but this has little evidence to support. Keep in mind that creationism is not a science; though some scientists may believe it, it is not a testable hypothesis and therefore is not science.
Does scientists think that Europa may have an icy surface an underground ocean active volcanoes or an atmosphere?
Of these four choices, out current understanding of Europa (and remember, everything is subject to change in the light of more recent discoveries) indicates that Europa may have large liquid oceans under a layer of ice. There are interesting surface features that appear to be large ridges; these might have been formed by cracks in the icy surface, and liquid or vapor escaping to the surface - and then freezing into ridges as the cracks…
