“Four space telescopes – Chandra, XMM-Newton, Spitzer, and WISE – combined to make a new discovery on a very old supernova remnant. Chinese astronomers witnessed an event in that location in 185 AD, documenting a mysterious ‘guest star’ that remained for 8 months. The new data show that RCW 86 was created by a Type Ia supernova explosion. This type of supernova is caused when a white dwarf pulls material from a companion star until a thermonuclear reaction occurs.
