As stars like the Sun enter the final stages of their lives, they expand and come off their outer layers, swallowing and destroying nearby planets.
Astronomers discovered two rings of planetary debris around the white dwarf J1328−1450. The finding could help to understand the future of the Solar System.
Astronomers have found a unique double disk of debris around the white dwarf WD J1328−1450. Two surviving planetesimals appear to be maintaining two separate gas rings. This sheds new light on the fate of planetary systems, including our own. White dwarfs are the compact, extinct cores that remain when stars like our sun have run out of fuel […] More science?

Around the White Dwarf J1328−1450, two separate rings of gas, originating from planetary debris, seem to pull out. Their unusual arrangement betrays four rather than the usual two peaks in the light spectrum. Two hitherto invisible, surviving celestial bodies could continuously generate new gas and thus maintain the ring structure. Garching near Munich (Germany). White Dwarfs are the compact remains of burnt out stars. Our sun will also one day …
