The Red Bubble: Supernova Remnant SNR 0509-67.5 in Dorado | STScI FriendsofNASA.org: This video presents a visualization of the supernova remnant known as SNR 0509-67.5. The delicate sphere of gas, photographed by NASA's Hubble Space Telescope, is the result of gas that is being shocked by the expanding blast wave from a supernova. 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
