ASAS-SN-15lh facts for kids
- "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".
