NASA’s planet hunter spied 2,200 candidate worlds in its first 2 years


A NASA spacecraft built to detect alien worlds has completed its first two years of work, and the tally is set: the mission carried 2,241 new ones. exoplanet candidates for scientists to study.

The transiting exoplanet study satellite (TESS) launched in April 2018, designed to spend two years perusing most of the sky. Each month, the spacecraft turns onto a new strip of stars and stares, observing the characteristic drops in brightness caused by a planet crossing between the star and the telescope. In a new catalog, astronomers offer a detailed look at a series of planet candidates that the spacecraft identified in its first two years of work.
