Star 'dies' after passing close to supermassive black hole 
A flash in the sky observed in 2015 was actually a supermassive black hole consuming a star that strayed too close to it, according to new research. Earlier called 'the brightest supernova ever detected', the phenomenon ripped the star apart in a process called 'spaghettification', which released a burst of radiations nearly half a trillion times brighter than the Sun.
