Talk Summary

I will relate the recent identification of the TRAPPIST-1 planetary system. It is composed of multiple Earth-sized planets, with good chances to have surface temperatures allowing liquid water to persist. Although similar to Earth and Venus in some aspects, those planets are different in other aspects. The star they orbit has a size barely larger than Jupiter’s. I will explain why we search for planets orbiting such odd stars and describe how the TRAPPIST-1 planets provide us with our first opportunity to search for life beyond the Solar System.
