For the first time, NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS) was able to watch the “cataclysmic phenomenon” of a star being torn apart by a black hole from beginning to end. Using follow-up observations from telescopes, astronomers were able to capture unprecedented data about the star-destroying events known as tidal disruptions.
