G292.0+1.8 & Kepler's Supernova Remnant: Supernova remnants representing two different types of supernova explosions.
Caption: A new study of images from Chandra shows that the symmetry of the supernova remnants, or lack thereof, reveals how the star exploded. G292.0+1.8 (left) represents a type of supernova where a massive star collapses on itself. The shape of this type of remnant is relatively asymmetric. The Kepler supernova remnant (right) is from a family of supernovas produced by a thermonuclear explosion on a white dwarf. Kepler and other remnants like it are more symmetrical in shape than G292 and its brethren.
