Afterglow of Supernova Remnant N132D - Universe Today
NASA's Hubble Space Telescope took this beautiful photograph of supernova remnant N132D, located in the Large Magellanic Cloud - a satellite galaxy to our Milky Way. By measuring the wispy cloud, astronomers estimate that the original star probably detonated about 3,000 years ago. A supernova-generated shockwave is traveling through space at a velocity of more than 2,000 kilometers per second (4 million mph), and colliding with surrounding material. This causes the material to heat up to millions of degrees so we can see it from here on Earth.
