Multi-telescope view two million times sharper than human eye reveals black hole
Scientists spaced thousands of miles apart discovered a super massive black hole inside a quasar some five billion light-years from Earth
Scientists using three telescopes spaced thousands of miles apart have caught the best look ever of the center of a distant quasar, an ultra-bright galaxy with a giant black hole at its core.
By linking powerful radio telescopes in Chile, Arizona and Hawaii together, astronomers created a deep-space observing system with 2 million times sharper vision than the human eye, which gave them the most detailed direct view ever of a supermassive black hole inside a galaxy 5 billion light-years from Earth.
The telescopes revealed a fresh look at the quasar 3C 279, a galaxy in the constellation Virgo that scientists classify as a quasar because it shines ultra-bright as massive amounts of material falls into the giant black hole at its core. The black hole is about 1 billion times the mass of the sun, with the linked-up telescopes providing details down to a resolution of 1 light-year or less, researchers said in an announcement today (July 18).
The new view used an astronomy technique called interferometry and marked "a remarkable achievement for a target that is billions of light-years away," researchers with the European Southern Observatory explained in a statement."The observations represent a new milestone towards imaging supermassive black holes and the regions around them."
