These cosmic ribbons of gas have actually been left by a titanic outstanding surge called a supernova. DEM L249 is believed to be the residue of a Type 1a supernova, the death of a white dwarf star. White dwarf stars are normally steady, however in a double star– 2 stars orbiting each other– a white dwarf can gravitationally pull a lot matter from its buddy that it reaches emergency and blows up.

DEM L249, situated in the Large Magellanic Cloud, is an uncommon supernova residue. Astronomers utilizing NASA‘s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton discovered its gas was hotter and shone brighter in the X-rays than the residue of a normal Type 1a supernova. Astronomers suspect DEM L249’s white dwarf star was more huge than anticipated– much heavier stars expel more gas– which likewise indicates it would have passed away previously in its lifecycle.

Hubble took this image while looking for making it through buddies of white dwarf stars that went supernova in the Large Magellanic Cloud.
