Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Earth. Kepler’s supernova remnant is the debris from a detonated star that is located about 20,000 light years away from Earth in our Milky Way galaxy. The Vela Supernova Remnant is an object within the constellation of Vela, which can only be seen in the southern Hemisphere. It is about 6,000 light years away. Around 10,000 years ago a massive star exploded as a supernova that would have been easily visible from Earth.
