This week, NASA announced that the Kepler spacecraft mission has discovered 1,284 more planets in addition to what it's already discovered. This brings Kepler's total to more than 2,000 planets discovered in a narrow patch of the sky that's "about the size of your fist, if you hold your fist up to the sky," says Iowa State University astronomer Steve Kawaler.
In this River to River interview, Ben Kieffer sits down with Kawaler to talk about the implications of the discovery, as well as the next steps towards finding planets in the “Goldilocks zone,” where planets are a good distance from their star, and where liquid water and life could exist.
Kawaler has worked on the Kepler mission in the past, and he is now involved in the Transiting Exoplanet Survey Satellite (TESS) mission, a kind of follow-up to Kepler. The hope with the TESS mission is to discover thousands of exoplanets in orbit around the brightest stars in the sky.
"If we're successful in doing that, and we should be - there's about a half a million stars in the catalog that we'll be looking at - then we'll be able to use ground-based telescopes and the next generation of space-based telescopes to look at the atmospheres of those newly discovered planets and look for signs of life in the atmospheres."
