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...

We take an imaginary trip around our Solar System to hear the history of chemical attempts to find life, starting in the late 1950s. Among our stops on the tour include Venus, Mars, Europa, and Titan. Included in the tour are temperature measurements, spectroscopic views, gas chromatography, radioactive labeling, photographs, electrical conductivity, and more.
