This image, created from data obtained from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope, shows a part of the roughly circular supernova remnant known as RCW 86. This remnant of an exploded star may be the one observed in 185 AD by Chinese astronomers. By studying it, astronomers gained a better understanding of new details about the role of supernova remnants as the Milky Way's super-efficient particle accelerators.

Astronomers gained a better understanding in 185 AD?

I don't get it.. If it was observed in 185 AD by Chinese Astronomers, how was it observed again now?!

The above picture is supposed to be the dead corpse of the supernova observed by Chinese astronomers in 185 AD. This supernova, first thought to be a star by Chinese astronomers, was visible for months.
