Astronomy Today@astronomytodayAstronomers say they found a gas giant born from the debris of a dying star, a so-called phoenix planet. It may be a little heavier than Jupiter and orbits a white dwarf about 250 light years away.
Unlike Earth, it came from material a dying star had thrown off, and its chemistry, heavy with niobium, copper and zinc, backs that up. It orbits every 4.4 days, so close that the white dwarf's ultraviolet light is evaporating its outer atmosphere.
Lead author Jamie Williams hopes the James Webb Space Telescope will confirm the findings, which relied on Hubble, TESS and FUSE data.
