Astronomy Today@astronomytodayAstronomers have found two distinct bands of gas and debris around a dead star 1,600 light-years away. The star, a white dwarf called WD J1328–1450, is the compact remnant of a Sun-like star that used up its fuel.
The bands are split by a gap and stayed in the same arrangement for over two years. Researchers think two leftover planetary bodies may be keeping them in place, with the outer one possibly around Pluto's size.
Neither body has been seen directly; their presence is inferred from the odd motion of the gas.
