I give a brief history of finding planets around other stars, including discovery by gravitational wobbling, dimming as the planet crosses in front of its star, and even seeing an actual planetary image by blocking the star's glare. I discuss what sort of spectroscopic signals might be present for life in a planet's atmosphere. Finally I offer some planets already detected whose temperatures appear to be in the range of terrestrial life, and what's in their atmospheres. Support the show Supp...
