Star Explosion
Astronomers have seen what could be the most powerful supernova ever detected.OK
The exploding star was first observed back in June last year but is still radiating vast amounts of energy.
At its peak, the event was 200 times more powerful than a typical supernova, making it shine with 570 billion times the brightness of our Sun.
Researchers think the explosion and ongoing activity have been boosted by a very dense, highly magnetised, remnant object called a magnetar.
This object, created as the supernova got going, is probably no bigger than a major city, such as London, and is likely spinning at a fantastic rate - perhaps a thousand times a second.

I see it was something like 80 billion lightyears away, in other words it happened 80 billion years ago. Sobering to think that if a similar event happened to a close star we would all be dead before we knew it was coming. However I believe the experts assure us we have no close stars of sufficient magnitude for this to happen, not that it matters. Shades of Tom Lehrer's 'We will all go together when we go!!"
Saw it yesterday, wasn't that impressed by the image.
Also watched this on CBS news yesterday.
Too big for the Museum.

Apologies, it was 3.8 billion light years away. Still a helluva long way !!
