Title:
The Gum Nebula Supernova Remnant
Explanation:
Because the Gum Nebula is the closest supernova remnant [ http://antwrp.gsfc.…], it is actually hard to see. Spanning 40 degrees [ http://math.rice.ed…] across the sky, the nebula is so large and faint [ http://antwrp.gsfc.…] it is easily lost in the din of a bright and complex background. The Gum Nebula [ http://www.britanni…], highlighted nicely in the above wide angle photograph [ http://www.celestia…], is so close that we are much nearer the front edge than the back edge, each measuring 450 and 1500 light years [ http://chandra.harv…] respectively. The complex nebula [ http://adsabs.harva…] lies in the direction of the constellations [ http://aibn47.astro…] of Puppis [ http://www.astro.wi…] and Vela [ http://www.astro.wi…]. Oddly, much remains unknown about the Gum Nebula [ http://www.edpscien…], including the timing and even number of supernova explosions [ http://observe.ivv.…] that formed it.
