NASA Astronomers Observe Birth of Red-Dwarf Star System –“Orbited By Its Planet in a Week”


AU Mic Star System


When the TESS (Transiting Exoplanet Survey Satellite) mission was launched in 2018, NASA predicted that the space telescope would discover thousands of planets — including a handful of worlds that may be habitable to aliens. TESS targets stars 30 to 300 light-years away and about 30 to 100 times brighter than the Kepler Spacecraft targets, which are 300 to 3,000 light-years away. Now, scientists using data from TESS and retired Spitzer Space Telescope have announced the discovery of a planet about as large as Neptune that orbits the young nearby star AU Microscopii –still surrounded by a disk of debris left over from its formation– in just over a week.
