Astronomers discover second-generation planet made by dying star
(NewsNation) — Astronomers have discovered evidence of a second-generation planet found around a white dwarf, according to a new study published in Nature Astronomy.
Researchers focused on white dwarf star HS 0209 0832, the core remnant of a low-mass star that burned through its nuclear fuel.
They discovered chemical signatures indicating the existence of a second-generation planet, a world formed from the cast-off remnants of the dead star.
