Scientists set to unveil first picture of a blackhole
On Wednesday , astronomers across the globe will hold"six major press conferences" simultaneously to announce the first results of the Event Horizon Telescope , which was designed precisely for that purpose.Of all the forces or objects in the Universe that we cannot see - including dark energy and dark matter - none has frustrated human curiosity so much as the invisible maws that shred and swallow stars like so many specks of dust.
"It has a gravitational pull strong enough to make stars orbit around it very quickly - as fast as 20 years." "If you're on the inside of it, you can't escape because you would need infinite energy. And if you are on the other side, you can - in principle." In April 2017, eight such radio telescopes scattered across the globe - in Hawaii, Arizona, Spain, Mexico, Chile, and the South Pole - were trained on two black holes in very different corners of the Universe to collect data.Oddsmakers favour Sagittarius A*, the black hole at the centre of our own elliptical galaxy that first caught the eye of astronomers.
TESTING EINSTEIN The other candidate is a monster black hole - 1,500 times more massive even than Sag A* - in an elliptical galaxy known as M87. Breakthrough observations in 2015 that earned the scientists involved a Nobel Prize used gravitational wave detectors to track two black holes smashing together.
