| Keywords: snr supernova remnant hubble hst heritage0509-67.5 heritage0509675 dorado dor wfc3 uvis acs wfc round abstract circle texture black background bubble A delicate sphere of gas, photographed by NASA's Hubble Space Telescope. The shell, or bubble, is the result of gas that is being shocked by the expanding blast wave from a supernova. Called SNR 0509-67.5, the bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud (LMC), a small galaxy about 160,000 light-years from Earth. Ripples in the shell's surface may be caused by either subtle variations in the density of the ambient interstellar gas, or possibly driven from the interior by pieces of the ejecta. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 11 million miles per hour (5,000 kilometers per second). Hubble's Advanced Camera for Surveys observed the supernova remnant on Oct. 28, 2006, with a filter that isolates light from glowing hydrogen in the expanding shell. These observations were then combined with visible-light images of the surrounding star field that were imaged with Hubble's Wide Field Camera 3 on Nov. 4, 2010. hubblesite.org/gallery/album/pr2010027a/ A delicate sphere of gas, photographed by NASA's Hubble Space Telescope.
