... 2003 April 20 . The Gum Nebula Supernova Remnant . ... Explanation: Because the Gum Nebula is the closest supernova remnant , it is actually hard to see. Spanning 40 degrees across the sky, the nebula is so large and faint it is easily lost in the din of a bright and complex background. The Gum Nebula , highlighted nicely in the above wide angle photograph , is so close that we are much nearer the front edge than the back edge, each measuring 450 and 1500 light years respectively. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...
