When I was born, Mars was thought to have canals. Science fiction movies had aliens attacking the earth from each of the planets including Pluto which has been demoted from the rank of planet.. Within one lifetime¬†humans have collected moon rocks, sent robots to Mars and send probes beyond our own solar system. Today NASA’s newest telescope will begin to search the sky for black holes and other space oddities. What a lucky generation we have been to observe such marvelous revelations.
