The age of astrobiology has begun. We have a whole solar system — and a galaxy of star-warmed worlds beyond — to explore for life. How do we look for life here and way out there? How will we know it when we find it? Our exploration begins at Earth. We must apply what we are learning about our own amazing home planet to our search for life beyond. Our Speaker, Dr. Penny Boston, was Director of NASA's Astrobiology Institute at Ames Research Center. She will answer questions during the video premiere via YouTube Chat.
