These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short as seen in this stunning space wallpaper. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernova, but for SNR 0519 the star that exploded is known to have been a white dwarf star — a Sun-like star in the final stages of its life.
