Our solar system has some prime locations (besides Earth) for alien life.
The big moons of Jupiter may have oceans underground. Although they are driven by the same mechanism, their nature can be radically different.
NASA is exploring the idea of putting a lander on Europa to look for signs of life.
What tiny satellites could take a ride over to Europa? Here are five feasibility studies being considered to hitchhike on a NASA mission.
Europa is an ice-covered moon orbiting Jupiter that likely an ocean underneath. Perhaps that ocean contains life. Perhaps it doesn't. But we're not going to know for sure until we send a probe there to check things out.
NASA on Tuesday selected nine science instruments it believes will best address the burning question about whether Jupiter’s ocean-bearing moon Europa has indications of life.
Salt from an underground sea on Jupiter’s moon Europa may be seeping onto the surface, then darkening as it is exposed to radiation.
The astronomical juxtaposition couldn't be any more stark: in the series of observations above, Jupiter's icy moon Europa passes in front of Io, fellow Jovian moon, but also the most volcanically active place in the entire solar system.
