Astronomers at the European Southern Observatory (ESO) have discovered a debris disk around a white dwarf , consisting of the remnants of the solar system that once orbited it. For researchers, these structures could offer a clue as to what the end of our solar system will look like once the sun runs out of fuel .

The white dwarf J1328−1450 is located about 1,600 light-years from Earth. Astronomers were already aware of it thanks to star-mapping catalogs, but new observations taken with ESO’s Very Large Telescope (yes, that’s its real name) revealed that it is surrounded by a disk of debris with an unusual structure: Two distinct rings of gas separated by a gap.

According to the observatory , this disk of material is likely the remnant of the planetary system that once orbited J1328−1450. As it passed through a red giant phase and subsequently became a white dwarf, the star may have destroyed some of its planets and left other rocky bodies exposed to an extreme environment.…
