NASA Hubble telescope spots galactic holiday ornament

Sometimes when you see these amazing images from space you almost cannot believe they are real. In this case, the NASA's Hubble Space Telescope has spotted a red ring that looks remarkably like a Christmas tree ornament hanging in space.

According to NASA: The ring is actually a gas bubble formed as a result of gas that is being shocked by the expanding blast wave from a supernova. Called SNR 0509-67.5 (or SNR 0509), the bubble is the visible remnant of a powerful stellar explosion in the Large Magellanic Cloud, 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), NASA stated.

Astronomers said the  explosion was an example of an especially energetic and bright variety of supernova. Known as Type Ia, such supernova events are thought to result when a white dwarf star robs its partner of material, taking on more mass than it is able to handle, so that it eventually explodes, NASA stated.
