Incredible Supernova Bubble
In the spirit of the Christmas season I just couldn’t pass up a chance to share this marvelous photo from the Hubble space telescope. It reminds me of a beautiful translucent Christmas tree ornament. I wonder if you agree. Following the photo is a description of the nature of the space phenomenon. The scale of space-related distances and objects is absolutely amazing. What an awesome creator brought it all into existence.
A delicate sphere of gas, photographed by NASA’s Hubble Space Telescope, floats serenely in the depths of space. The pristine 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 (or SNR 0509 for short), 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).
