3 days ago · NASA launches exoplanet-hunting satellite TESS. Transiting Exoplanet Survey Satellite ( TESS) is a space telescope for NASA 's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. [6] It was launched on 18 April 2018, atop a Falcon 9 launch vehicle and ...

Apr 25, 2024 · The discovery of a terrestrial-mass free-floating planet candidate in the light curve of the star TIC 107150013 observed by the Transiting Exoplanet Survey Satellite (TESS) has recently been announced. A short-duration (~0.5 day), low-amplitude (~0.06 mag) brightening in the TESS light curve was interpreted as a short-timescale gravitational microlensing event. However, the purported event ...
