Spitzer made some of the first studies of exoplanet atmospheres (atmospheres of planets around stars other than our Sun). It confirmed two and discovered five of the seven Earth-size exoplanets around the star TRAPPIST-1 – the largest batch of terrestrial planets ever found around a single star. On Thursday, Jan. 30, engineers will decommission the Spitzer spacecraft and bring this amazing mission to a close.
