This exciting show describes how astronomers search for planets circling other stars. It explains the two main methods they use: studying minute “wobbles” of stars and detecting flickers in a star’s brightness. Only a few Earth-like planets have been found, and as of yet, no extraterrestrial life has been found on any of the worlds discovered so far. Yet, it’s likely to be only a matter of time before a world teeming with life shows up in astronomy surveys of stars in our galactic neighborhood.
