| Not just for finding planets: Exoplanet-hunter TESS telescope spots bright gamma-ray burst Posted: 30 Apr 2021 10:54 AM PDT NASA has a long tradition of unexpected discoveries, and the space program's TESS mission is no different. Astrophysicists have discovered a particularly bright gamma-ray burst using a NASA telescope designed to find exoplanets - those occurring outside our solar system - particularly those that might be able to support life. It's the first time a gamma-ray burst has been found this way. |
