The number of possible places in a galaxy for life as we know it to develop depends on the number of stars which have planets, the presence of necessary elements such as iron, oxygen, nitrogen, and carbon, and the freedom from nearby supernova which could sterilize an otherwise habitable planet. The good news, the Sloan Digital Sky Survey in New Mexico has reported the discovery more than 150,000 galaxies which are rich with the three life enabling properties. The bad news is we will get monologues and not dialogs since it will take 9 million years for radio waves from the closest one to reach us and another 9 million years for our answer to make the trip back.
