The TRAPPIST-1 exoplanet system has seven earth-like planets and is only 39 lightyears away! I am joined by Professor Adam Burgasser and Dr. Katherine Deck, both astrophysicists on the Nature paper to discuss the discovery of this planetary system.

NASA & TRAPPIST-1: A Treasure Trove of Planets Found

Originally published on Feb 22, 2017

Seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around a tiny, nearby, ultra-cool dwarf star called TRAPPIST-1. Three of these planets are firmly in the habitable zone.

Over 21 days, NASA’s Spitzer Space Telescope measured the drop in light as each planet passed in front of the star. Spitzer was able to identify a total of seven rocky worlds, including three in the habitable zone, where liquid water might be found.

The video features interviews with Sean Carey, manager of the Spitzer Science Center, Caltech/IPAC; Nikole Lewis, James Webb Space Telescope project scientist, Space Telescope Science Institute; and Michaël Gillon, principal investigator, TRAPPIST, University of Liege, Belgium.

The system has been revealed through observations from NASA’s Spitzer Space Telescope and the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, as well as other ground-based observatories. The system was named for the TRAPPIST telescope.

NASA’s Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA’s Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at Caltech in Pasadena. Spacecraft operations are based at Lockheed Martin Space Systems Company, Littleton, Colorado. Data are archived at the Infrared Science Archive housed at Caltech/IPAC. Caltech manages JPL for NASA.
