About 56 million years ago a star, exploded into what we call a Type 1A Supernovae.
Here it is announcing itself to us, we first detected this about 3 weeks ago and it's around peek brightness now, over time it will fade back down and we'll probabaly never see it again.
I love supernovae, that one star outshines everything in it's galaxy. All the other stars in that image around the same brightness are actually in our galaxy - so they're around ten thousand times closer.
Now if only Eta Carina would finally go, or better yet something I can see from the northern hemisphere!
