Supernova Remnant SH2-224 in Auriga

Supernova Remnant SH2-224 in Auriga

Sh2-224 is a very faint supernova remnant located approximately 14,700 light years distant in the constellation Auriga. This unusual celestial object is also designated VRO 42.05.01 and has been the object of considerable research using space and ground-based telescopes, including the x-ray astronomy German-US-UK ROentgen SATellite (ROSAT) and Canada's Dominion Radio Astronomy Observatory (DRAO). The nebula created by the supernova explosion is composed of two visual parts. It is postulated the supernova explosion created a bubble like structure. (Visible in the 'top center' of the image.) As the shockwave from the explosion progressed into a very low density region of the interstellar medium, a "wing" component was expelled. (Visible in the 'lower half' of the image.)

Supernova explosions are the end stage of the natural life cycle of very large stars. Such events are responsible for the distribution of heavy elements into the interstellar medium where they are incorporated in the birth of new star systems. Without this phenomenon, planets, such as the Earth along with life as we know it, would not be possible.
