The Medulla Nebula Supernova Remnant

What powers this irregular nebula? CTB-1 is the expanding gasoline shell that turn out to be left when a giant valuable particular person toward the constellation of Cassiopeia exploded about 10,000 years ago. The dear particular person seemingly detonated when it ran out of aspects, shut to its core, that could maybe maybe originate stabilizing strain with nuclear fusion. The resulting supernova remnant, nicknamed the Medulla Nebula for its mind-take care of shape, silent glows in visible light by the warmth generated by its collision with confining interstellar gasoline. Why the nebula also glows in X-ray light, though, remains a thriller. One speculation holds that an brisk pulsar turn out to be co-created that powers the nebula with a like a flash outwardly provocative wind. Following this lead, a pulsar has lately been demonstrate in radio waves that appears to be like to had been expelled by the supernova explosion at over 1000 kilometers per 2d. Though the Medulla Nebula appears to be like as clear as a pudgy moon, it’s so faint that it took 130-hours of exposure with two tiny telescopes in New Mexico, USA, to originate the featured image.
