... Wispy tendrils of hot dust and gas glow brightly in this ultraviolet image of the Cygnus Loop nebula, taken by NASA s Galaxy Evolution Explorer. The nebula lies about 1,500 light-years away and is a supernova remnant, left over from a massive stellar explosion that occurred between 5,000 to 8,000 years ago. ... The filaments of gas and dust visible here in ultraviolet light were heated by the shock wave from the supernova, which is still spreading outward from the original explosion. ...
