The team created a new model to show the moon is likely to have subsurface oceans under its icy surface and we can't yet rule out its ability to host alien species.
Nasa planetary scientists Mohit Melwani Daswani said: "Europa is one of our best chances of finding life in our Solar System.
"NASA's Europa Clipper mission will launch in the next few years, and so our work aims to prepare for the mission, which will investigate Europa's habitability.
"Our models lead us to think that the oceans in other moons, such as Europa's neighbour Ganymede, and Saturn's moon Titan, may also have formed by similar processes.
"We still need to understand several points though, such as how fluids migrate through Europa's rocky interior."
Previous research has also found that Europa is quite salty, leading scientists to hope it has oceans similar to those we have on Earth.
