How Deep Must Life Hide to be Safe on Europa?Moffett Field CA (SPX) Apr 02, 2012 Considered one of the best potential sources for extraterrestrial life in the solar system, Europa may hide life in the ocean deep beneath the moon's icy crust. Some organisms could even travel to the surface through cracks and instabilities in the crust. But radiation from Jupiter's magnetosphere constantly douses the tiny moon and could annihilate life at shallow depths, making it difficult to detect with an orbiter or lander. A group of scientists are seeking to experimentally determine just ho ... read more |
