The Red Bubble: Supernova Remnant SNR 0509-67.5 [Ultra HD]

Posted by

This movie 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 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).... Read More إقرأ المزيد | Share it now!
