Look down at your feet. There – you’re looking at a planet. Now look into the night sky and you should be able to spot a few more. After that, spotting additional planets becomes really hard, especially when you’re trying to find them orbiting other stars. This week we discuss the techniques astronomers use to locate distant worlds.
Astronomy Cast is a weekly podcast hosted by Fraser Cain from Universe Today, and Dr. Pamela Gay (of Slacker Astronomy fame). Each week we take a fact-based journey through the cosmos to explain the discoveries in astronomy, and understand how we know what we know.
