Have you ever wondered how likely it is that we will find life -- in any form -- somewhere other than Earth? How about the likelihood of intelligent life elsewhere in the galaxy? NASA's Ask an Astrobiologist site might have the answers you seek.
Fielding approximately five questions a week, from questions like those in my opening paragraph to questions about the 2012 doomsday hoaxes, NASA Senior Astrobiologist David Morrison certainly has his work cut out for him. Legitimate questions are on topics such as Mars (pictured at right), global warming, habitability of Earth as the Sun changes over time, exoplanet discoveries, and asteroid tracking. Unfortunately, the largest number of questions answered (and, I'm assuming, asked) recently are doomsday-related, which is a shame because the multitude of topics that could be addressed are lost in the deluge of "the end of the world" panic. Fortunately, the site contains a search feature that makes it possible to find an answer on a topic that interests you. Ask an Astrobiologist has been fielding questions since October 2001 and contains more than 2,000 answered questions, even on topics that aren't necessarily related to astrobiology.
