RX J0852.0-4622 is a supernova remnant that exploded in 1200 CE. It was about 660-800 light-years away from us. This is still somewhat controversial since astronomers disagree on the exact distance and when it went supernova (since there are no historical records only residual Antarctic Ice Cores).
There isn't any real way to completely attempt to see a supernova. This is becuase the stars are hundreds or even thousands of light years away, which makes it impossible to tell when the explosion will be visible on Earth. A supernova simply looks like a distant star brightening up very quickly for a second.
The supernova itself is typically the last stage of the stars life. It vastly varies between stars with different masses, but is started when nuclear fusion stops.

ReplyDeleteWhat is the difference between a neutron star and a black hole? Is it just mass?
ReplyDeleteMainly. If a neutron star continues to get more massive it will turn into a black hole.
DeleteWhich is more threatening, a Neutron Star or a Black Hole?
ReplyDeleteWhen was the first supernova noted in history?
ReplyDeleteAccording to NASA.com, the first noted supernova was in 185 A.D. It was called RCW 86, and was discovered by Chinese astronomers.
