Hubble data suggests first "phoenix planet" born from dying star's remnants

A post says archival Hubble spectra revealed niobium at more than 1,000 times the Sun's level in a white dwarf. Researchers suspect a Jupiter-sized planet formed from material the star shed as it died; its atmosphere may be feeding gas back onto the star. TESS picked up a faint 4.4-day signal consistent with a giant in a tight orbit. The candidate would be the first second-generation planet found around a white dwarf if confirmed.
