| M83, a spiral galaxy about 15 million light years from Earth, is one of the inner most X-ray observations ever product of a supernova from a spiral galaxy past our personal. This full-area view of the spiral galaxy suggests the low, medium, and high-electricity X-rays determined in crimson, green, and blue respectively. The distribution of X-rays with electricity indicates that SN 1957D incorporates a neutron big name, a unexpectedly spinning, dense big name formed when the core of pre-supernova superstar collapsed. This neutron megastar, or pulsar, can be producing a cocoon of charged particles transferring at near the rate of mild referred to as a pulsar wind nebula. If this interpretation is showed, the pulsar in SN 1957D is discovered at an age of 55 years, one of the youngest pulsars ever seen |
