As mankind begins to explore more of the universe, Astrobiologists will be in demand to help establish settlements on other planets and work to plan our future in space. From General Sciences to human Philosophy, the study of Astrobiology encompasses a large spectrum of scientific disciplines free from sensationalism commonly attributed to today's space topics. University of Edinburgh's Charles Cockell is generously offering a free course about Astrobiology and the Search for Extraterrestrial Life starting today on Coursera. It's not too late to sign up and enjoy these very informative video lectures. For those interested, participation in the course discussions as well as completing homework assignments can also earn a certificate of accomplishment.
