Astronomers have found a way to accurately measure the spin of a supermassive black hole for the first time and as expected, it's pretty darn fast -- nearly-the-speed-of-light fast. The black hole in question resides 60 million light years away at the centre of the NGC 1365 spiral galaxy, is a mind-boggling 3.2 million kilometres in diameter, has a mass two million times that of our Sun and is spinning at a rather impressive 1.08 billion km/h. http://www.wired.co.uk/
Scientists have discovered the first binary system ever known to consist of a black hole and a ‘spinning’ star – or more accurately, a Be-type star. Although predicted by theory, none had previously been found.
