Hubble Space Telescope data suggests a dead star may have given birth to a new planet

Astronomers re-examining archival observations from NASA's Hubble Space Telescope have found evidence suggesting that the white dwarf HS 0209+0832 could be orbited by a second-generation planet. The study, published on October 5 in Nature Astronomy, indicates unusual chemical abundances, particularly high levels of niobium, around the white dwarf. This suggests that material expelled by the dying star may have later formed a new, Jupiter-sized gas giant.
