On April 18, 2018, NASA's Transitting Exoplanet Survey Satellite (TESS) took to space for the first time. By August, it began capturing the light curves of distant stars for signs of planetary transits, effectively picking up where the Kepler Space Telescope left off. Now, just a few months away from the end of its primary mission, NASA has put a year's worth of images of the southern sky together to create the beautiful mosaic you see here.
This panoramic view of the southern sky is based on 208 TESS images, which were taken during the mission's first year of science operations — which wrapped up this past July 18th. In that time, the spacecraft gathered data on many interesting events in the southern sky, as well as light curves that led to the discovery of 29 exoplanets so far with more than 1,000 candidate planets that are now being investigated.
