Oldest Recorded Supernova

Using data from four telescopes and comprising an image of the supernova remnants, NASA was able to determine the type and the cause of a supernova that occurred back in 185 AD, as observed by the Chinese. Scientists were not only able to classify it as a Type Ia supernova, but were also able to figure out how the star had grown so large in so little time. It had been the result of the star (a white dwarf) blowing winds to create a low-density 'cavity' surrounding it. This cavity is what enabled it to be a larger explosion than usual when the white dwarf went supernova.

The star is called RCW 86, and is at an estimated 8,000 light years away.

Wow, I read this same article on yahoo. I was amazed that almost 2,000 years later scientists were able to observe and uncover the mystery of this supernova. It really made me realize how far science and technology has come. Also, if you guys want to see a similar article on this, go to:
