Almost all galaxies have such supermassive black holes at their centers, Read more on. These observations were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of 1.3 mm. At the heart of our galaxy lies a monstrous black hole named Sagittarius A. The three panels on the right show changes in brightness caused by an earlier outburst of Sagittarius A. But because Sagittarius A* is 2,000 times closer to Earth than M87*, the Event Horizon Telescope was able to observe both black holes at a similar resolution – giving astronomers a chance to learn about the universe by comparing the two. We present the first Event Horizon Telescope (EHT) observations of Sagittarius A (Sgr A), the Galactic center source associated with a supermassive black hole. Sagittarius A, the black hole at the centre of the Milky Way Galaxy, taken with NASAs Chandra X-Ray Observatory. Chris Impey, an astronomer at the University of Arizona, explains how the team (which included two scientists from Wits) got this image and why it is such a big deal. The black hole at the center of this galaxy, named M87*, is a behemoth 2,000 times larger than Sagittarius A* and 7 billion times the mass of the Sun. On May 12, 2022, astronomers on the Event Horizon Telescope team released an image of a black hole called Sagittarius A that lies at the center of the Milky Way galaxy. In 2019, the Event Horizon Telescope team released the first image of a black hole – this one at the center of the galaxy M87. It has been proposed that Very Long Baseline Interferometry (VLBI) at submillimeter waves will allow us to image the shadow of the black hole in the center of.

The processing time was equivalent to running 2,000 laptops at full speed for a year. By studying both black holes at the same time.

They then blended all of these images together to produce the final, beautiful, accurate image. It’s called M87 and it’s a massive black hole that’s about 2,000 times bigger than the supermassive black hole known as Sagittarius A. Until now, the presence of Sagittarius A (Sgr A) could only be suspected, either from a few radio emissions or by observing the paths of stars orbiting at high speed around a gigantic yet invisible object. To turn it all into an accurate image, the team used supercomputers to produce millions of different images, each one a mathematically viable version of the black hole based off the data collected and the laws of physics. The EHT collaboration has now obtained the very first image of Sagittarius A, the supermassive black hole at the heart of our Galaxy.
