This is the first time that astronomers have measured the very fast moving gas ejected by the supernova explosion, which was invisible until observed by Hubble with the STIS ultraviolet detectors. This gas is glowing in the ultraviolet because it is slamming into the remains of the gas lost by the supernova star about 20,000 years before it exploded.
