Rare Type Of Supernova Extinguishes Star At Unprecedented Speed

Supernovae produce some of the most powerful explosions in the cosmos, expelling a doomed star’s contents at velocities reaching 10 per cent the speed of light. It usually takes a few weeks or months for a supernova to fade into nothingness, but astronomers have now documented a record-setting case in…

Last year, astronomers recorded the brightest supernova explosion ever seen. Follow up observations now suggest this cataclysmic event wasn’t a supernova at all, but rather, an extremely rare celestial phenomenon involving a supermassive black hole and a rather unfortunate star.

In early 2016, astronomers will be looking at a specific part of the sky, knowing with near certainty that a supernova will appear. How is it possible to predict such events? The answer has to do with an effect known as gravitational lensing.
