This composite X-ray (red and green)/optical (blue) image reveals a cat-shaped image produced by the remnants of two exploded stars in the Large Magellanic Cloud galaxy. Although the shells of hot gas appear to be colliding, this may be an illusion.
Chandra X-ray spectra show that the hot gas shell on the upper left contains considerably more iron than the one on the lower right. The high abundance of iron implies that this supernova remnant is the product of a Type Ia supernova triggered by the infall of matter from a companion star onto a white dwarf star.
