1/23/2024 0 Comments Event horizon telescope images![]() ![]() Researchers using the Event Horizon Telescope hope to generate images like this of Sag. In the meantime, the team has released computer model images of what they hope to see. That four years ended in April 2017, but the team of 200 scientists and engineers are still analyzing the data. The EHT project gathered data on Sagittarius A, and one other black hole called M87 in the center of the Virgo A galaxy, over a four year period. They also hope to detect some of the dynamics at work near the hole as orbiting matter in the accretion disk reaches relativistic speed. Researchers with the EHT hope that their observations will eventually provide images of the intense gravitational effects that we expect to see near the black hole. The EHT should give us the first image of a black hole’s event horizon. The EHT is seven separate facilities around the world linked through interferometry. By measuring the electromagnetic energy from the region surrounding the black hole with multiple radio dishes at multiple locations, some of the properties of the source can be derived. It’s not one telescope, but rather a linked system of radio telescopes across the globe all working together using interferometry. The EHT is an international collaboration designed to investigate the immediate surroundings of a black hole. But we may be close to getting an image of Sagittarius A’s event horizon, thanks to the Event Horizon Telescope (EHT). No matter, no light, and no information can escape. The event horizon is the point of no return. The intense gravitational pull prevents anything, even light, from escaping. Nobody’s ever seen a black hole’s event horizon. And that image may pose a challenge to Einstein’s Theory of General Relativity. But soon we may have an image of Sagittarius A’s event horizon. ![]() The object is the Super-Massive Black Hole (SMBH) at the center of our Milky Way galaxy, called Sagittarius A. The largest object in our night sky-by far!-is invisible to us. ![]()
