PFS is an instrument that astronomers use at the Magellan Clay Telescope to look for the signature of exoplanets. Since stability is very important, PFS is rarely opened. The time-lapse of their work is a rare look inside a world-class planet finding instrument! Credit Courtesy Johanna Teske and Cynthia Hunt.
