This is the TESS 2yr sky map. The Transiting Exoplanet Survey Satellite (TESS) is the next step in the search for planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets. TESS aims for 50 ppm photometric precision on stars with TESS magnitude 9-15.
TESS launched on April 18, 2018, aboard a SpaceX Falcon 9 rocket. This dataset is made of observations made during the first 2 years of the mission. See
