Scientific American: The Search for Alien Life
Scientific American: The Search for Alien Life

Are we alone in the universe? Its a question that every school kid has probably asked at some time - and scientists in particular want an answer. In this special online issue, Scientific American authors review the evidence for and against the existence of ETs. In Where Are They?, Ian Crawford ponders what it means that all of our surveys so far have come up empty handed. In Is There Life Elsewhere in the Universe?, Jill C. Tarter, director of research for the Search for Extraterrestrial Intelligence (SETI) Institute, and her colleague Christopher F. Chyba assert that the search has only just begun. Other articles examine the cases to be made for relic life on Mars and other bodies in our solar system, as well as the plans to launch a new space telescope for spying on distant worlds. Buy the issue, read the articles and, the next time you gaze up at the night sky, make up your own mind. - the Editors
