NASA posts spectacular multi-color footage of exploding starSupernovas occur quite often in space and NASA is now posting footage of them. This is what the Crab Nebula – a supernova remnant – looks like in pictures collected by several telescopes conducting space research.
If you have ever wondered what happens to a star when it explodes, NASA is trying to provide you with an answer. A supernova, which is often seen in other galaxies, is the process in which a star explodes as the core collapses unable to tolerate its own gravitational force. This incredible phenomenon recorded and posted by NASA displays the supernova remnant called the Crab Nebula.
The Crab Nebula was discovered by Chinese astronomers in 1054 and is considered the brightest supernova observed by astronomers at that time. It is located 6,500 lightyears from Earth, it has a diameter of 11 lightyears and grows at a speed of 1,500 kilometers per second.
