X-ray & Infrared Images of G299.2-2.9
These images shows G299.2-2.9 in X-ray light from Chandra and infrared light from the Two Micron All-Sky Survey (2MASS). Evidence points to G299.2-2.9 being the remains of a Type Ia supernova, where a white dwarf has grown sufficiently massive to cause a thermonuclear explosion. Because it is older than most supernova remnants caused by these explosions, at an age of about 4,500 years, G299.2-2.9 provides astronomers with an excellent opportunity to study how such remnants evolve over time.
