by In the year 185 A.D. Chinese astronomers witnessed a temporary 'guest star' emerge in the sky.
A new image taken by a camera designed to study dark matter has revealed remnants of an ancient supernova explosion in unprecedented detail.
The image, captured by the Dark Energy Camera on the National Science Foundation’s (NSF) Víctor M. Blanco 13.2-foot (4 meters) Telescope at the Cerro Tololo Inter-American Observatory in Chile, shows scattered tendril-like clouds of dust and gas dispersing around the supernova's central point.
These torn pieces encircle an area larger than the apparent size of the full moon set between the constellations Circinus and Centaurus in the southern sky.
The odd cloud, known to astronomers as object RCW 86, is believed to be material from a star that exploded more than 1,800 years ago with such ferocity that it drew the attention of ancient Chinese astronomers and chroniclers.
