NASA's Hubble Space Telescope has imaged a pristine bubble of shocked gas from 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.
