A study led by a researcher from the University of Amsterdam said that one side of the nebula is slowly spreading from the dead star. It looks like a Supernova has bumped into space. The study was published in the Astrophysical journal.
The star’s demise was caused by a massive shock wave passing through a gas cloud, according to a new research. According to the researchers, the shock wave is revving at different speeds, causing one component to plummet back toward the source of the Supernova explosion. It’s referred to as a “reverse shock” by the author.
The shock wave’s route was investigated using X-ray photographs acquired by NASA’s Chandra X-ray Observatory, an orbiting observatory. The data revealed that the western part of the shock wave was diminishing oppositely. As a result, reversal shock occurs. The shock waves are also travelling towards the Supernova core, according to the experts. The Supernova average speed is 21.6 million km/h, making it one of the fastest recorded shock waves.
