Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a sub-Neptune exoplanet orbiting a nearby M dwarf star. The newly found alien world, designated TOI-2257b is about two times larger than the Earth. The finding is reported in a paper published November 2 on the arXiv pre-print server.
