Researchers using JWST discovered RX J0534.0-0221 b, a giant planet around a young M-dwarf star in the β Pictoris moving group, along with a debris disk. At 2.8 Jupiter masses and ~14 au from its host star, it is one of the lowest-mass directly imaged planets and the first around an M-dwarf confirmed via common proper motion.
Astronomers using the James Webb Space Telescope have discovered mysterious bright objects called 'little red dots' from the early universe. Initially thought to be galaxies, they now appear to be either supermassive black holes or a newly proposed phenomenon called black hole stars—objects combining massive stars with black holes at their cores. The discovery has sparked intense debate in the astronomical community.
