Only several months into its mission to search for alien worlds, NASA's Transiting Exoplanet Survey Satellite is already making new discoveries. According to Mother Nature Network, NASA officials confirmed the satellite found three exoplanets in its first three months. In the same regions of these new worlds, TESS also discovered 100 short-lived changes — most of which are likely stellar outbursts. Of those outbursts, six of them were supernova explosions.
