The Search for 100 Earths

Debra Fischer (Yale University)

The search for exoplanets is motivated by the question of whether life exists elsewhere.

Importantly, we will need to discover not just a few, but hundreds of these worlds to eventually gain a statistical understanding of whether life is rare, common, or ubiquitous and ground-based telescopes offer an ideal platform for carrying out decade-long surveys.
