Scientists have found remnants of small creatures in Antarctica under a deep layer of ice. The remains were found in mud that was brought up through a borehole. The findings might tell us something about the possibility of life on icy planets or moons
Ever since the Galileo probe provided compelling evidence for the existence of a global ocean beneath the surface of Europa in the 1990s, scientists have wondered when we might be able to send another mission to this icy moon and search for possible signs of life. Most of these mission concepts call for an orbiter or lander than will study Europa’s surface, searching the icy sheet for signs of biosignatures turned up from the interior.
