James Webb Space Telescope Reveals Exoplanet WD 1856b Survived Its Star's Death

The James Webb Space Telescope (JWST) has observed exoplanet WD 1856b, a massive planet orbiting a white dwarf 82 light-years from Earth, confirming its survival after its host star's demise. The planet was found to be significantly hotter than anticipated, around 126 degrees Celsius, with scientists suggesting that tidal forces from a nearby binary star likely reheated it and shifted its orbit closer to the white dwarf. This discovery provides crucial insights into the evolution of planetary systems in extreme environments, including the potential 'second life' of giant planets after their stars die.
