Twenty years ago we knew of exactly one planetary system: our own.

Today we know of more than 1000 confirmed planets around other stars, with a few thousand more candidate systems awaiting confirmation. This lecture will give an overview of Astrobiology from the perspective of an observational astronomer. It will begin with a review of the basic requirements for life and introduce the concept of “habitability” in an astrophysical context. From there, we will look at where in the universe we might expect to find life, starting within our solar system, and proceeding out among the newly discovered exoplanetary systems.
