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.
Outer space might be the toughest environment for life, but some hardy microbes have been able to survive in it for surprising amounts of time.
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.
What has Antarctica and Mars got in common? Mineral deposits from a briny subsurface aquifer suggest bacteria are hiding under the barren Antarctic landscape -- can the same be said for the red planet?
A ghostly apparition has long been known to follow Saturn moon Enceladus in its orbit around the gas giant. But until now, scientists have had a hard time tracking its source.
Scientists have found complex organic molecules in a planet-forming disk of gas, dust and ice swirling around a very young star, evidence that the building blocks for life may be common in the universe.
Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.
