A Supernova Bubble

Rate this post


This colorful bubble, taken by the Hubble Space Telescope, is the ambient gas being shocked by the expanding blast wave from a Type 1a supernova nearly 400 years ago. A supernova is what happens when a star explodes. This supernova remnant and its progenitor star reside in the Large Magellanic Cloud, a small galaxy about 160,000 light-years from Earth. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 11 million miles per hour.
