GoKawiilESO telescope spots split debris ring around distant white dwarf
Astronomers using the European Southern Observatory's Very Large Telescope have found a disk of gas and dust encircling the white dwarf J1328−1450, located roughly 1,600 light-years from Earth. The disk shows an unusual structure of two separate gas rings with a gap between them, which ESO says likely formed from the remains of planets and rocky bodies destroyed as the star evolved from a red giant into a white dwarf.
