Double Ring of Planetary Debris Around Dead Star Offers Preview of Our Solar System’s Fate
Astronomers discovered the first known double ring of vaporized planetary debris around white dwarf J1328−1450. The rings contain elements from shattered rocky worlds but differ chemically, suggesting multiple destroyed bodies or a separated planet. Surviving objects, ranging from asteroid-sized to Moon- or Pluto-sized, may gravitationally maintain the rings’ gap.
