Still More Cosmic Leftovers

This is a visualization of the supernova remnant known as SNR 0509-67.5 as seen by the Hubble Space Telescope. The delicate sphere of gas is being formed by the expanding blast wave from a supernova in the Large Magellanic Cloud, a small galaxy about 160,000 light-years from Earth. The ripples in the shell’s surface may be caused by either subtle variations in the density of the ambient interstellar gas, or they are 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 5,000 km/s.
