Content overview: “Hubble Data Reveals Evidence of Second-Generation Planet Forming Around White Dwarf”. A team of scientists has uncovered evidence of a planet forming around a white dwarf, the dense remnant of a Sun-like star, using decades-old Hubble Space Telescope data. The discovery, led by researchers at the University of Wisconsin–Madison and published in the journal Nature, suggests that planets can form not only from the gas and dust around young stars but also from the debris of dying ones. The white dwarf, known as WD 1856+534, is located about 80 light-years away in the constellation Draco.
The team detected a disk of gas and dust around the white dwarf, with a gap that could indicate the presence of a newly forming planet. This second-generation planet would be the first of its kind ever observed, offering insights into the fate of planetary systems after their host stars die.
