X-ray & Infrared Images of G299.2-2.9
This debris field, which glows brightly in X-rays, was left over when a star exploded about 4,500 years ago. This object, known as G299.2-2.9, belongs to a particular class of supernovas called Type Ia. Astronomers think that a Type Ia supernova involves a thermonuclear explosion - involving the fusion of elements and release of vast amounts of energy - of a white dwarf star in a tight orbit with a companion star. In the Chandra image, red, green, and blue represent low, medium, and high-energy X-rays, respectively, detected by the telescope. Infrared data show the stars in the Chandra field of view.
