The “biggest ever” black hole has been detected by astronomers* using a new technique, opening up “tantalising*” possibilities for space exploration. The findings – akin* to something straight out of a sci-fi film – by the Royal Astronomical Society show that the ultramassive black hole* is more than 30 billion times the mass of the Sun, and sits in a supergiant* galaxy* about 2.7 billion light years from Earth, ABC News reported.
