A stunning deep-space image of RCW 86, the remnant of a Type Ia supernova first observed by Chinese astronomers in 185 AD. This nebula, larger than the full moon in the sky, shows intricate filaments of gas ionized by the expanding shockwave of the ancient stellar explosion. Located 8,000 light-years away, its red and blue hues showcase the remnants of a thermonuclear detonation on a white dwarf star.
