“These cosmic puzzle pieces led a research team to the ancient flash’s likely culprit: a supernova whose remnants now form a fast-expanding nebula called Pa30. The nebula’s clouds move so quickly that, in the new research, scientists ... found that Pa30’s dust and gas could travel the distance from Earth to the moon in a whopping five minutes. By using that speed and calculating backward, the researchers determined that the nebula would fit a supernova that exploded around 1181
“The team found that Pa30 formed from a rare and relatively faint type of supernova, called a ‘Type Iax supernova.’ “Only around 10% of supernovae are of this type and they are not well understood. The fact that SN1181 was faint but faded very slowly fits this type
“Scientists also found that Parker’s star, one of the hottest stars in the Milky Way, is also a likely counterpart to the supernova. The nebula and the star are thought to be the result of a massive collision and subsequent merger of two dim stellar corpses known as white dwarfs.”
