Nasa Reveals The Oldest Supernova

Nasa has revealed another video of the oldest recorded supernova, RCW 86.

The magnificent star was an ancient mystery until October 2011.

Around 2,000 years ago, in A.D. 185, Chinese astronomers spotted what they called a "guest star" which appeared suddenly and remained in the night sky for 8 months.

Now a composite image of infrared observations reveals the guest star was actually the first ever recorded supernova explosion.

It hasn't been until recently that the technology has been available to solve the mystery.

Spitzer and WISE observations combined with data from Nasa's Chandra X-ray Observatory and the European Space Agency's XMM-Newton Observatory, confirm the the guest was in fact a white dwarf star.
