Astronomers Detect Potential 'Second Generation' Planet Around Dying White Dwarf Star

Astronomers have potentially detected the first-known 'second-generation' planet, a Jupiter-like world that likely formed from debris around a dying stellar white dwarf identified as HS 0209+0832. The unusual atmospheric composition of the white dwarf prompted a reanalysis of 25-year-old Hubble Space Telescope data, with findings appearing in the journal Nature Astronomy. This discovery offers new insights into planetary formation around stellar remnants.
