Fact of the Day

Think it would be easy to use a spacecraft to find life on other planets? As an exercise, scientists used observations from Galileo's Earth flybys to look for life on Earth. Galileo detected several signs of life as it passed by the Earth for gravity assists in December 1990 and December 1992. The existence of oxygen and methane in the air and the strong infrared signature from the land areas were indications that something biological might be taking place. The only indication of intelligent life, however, were strong radio emissions that were difficult to attribute to natural causes.
