Will Dunham reported on this story for Reuters. Thursday's announcement was made in simultaneous news conferences in the United States, Germany, China, Mexico, Chile, Japan and Taiwan. These are thought to appear relatively soon after their galaxies are formed. And finally there are the supermassive black holes that are at the center of most galaxies. Intermediate-mass black holes have more mass. The smallest are called stellar-mass black holes. There are different kinds of black holes. A black hole has a gravitational pull that is so intense that nothing, not even light, can escape it once inside a certain region, called the event horizon. The project began in 2012 to try to directly observe the immediate environment of a black hole. The Event Horizon Telescope is a global group of observatories working to study radio sources linked to black holes. Lindy Blackburn, an EHT data scientist at the Harvard-Smithsonian Center for Astrophysics, said 'Sagittarius A* is over a thousand times less massive than the black hole at M87, but since it is in our own galaxy it is much closer and should appear just slightly larger on the sky.'

The researchers said that Sagittarius A*, despite being much closer to our solar system than M87, was harder to image. The M87 black hole is far more distant and large than Sagittarius A*. The image released in 2019 of the supermassive black hole in a galaxy called Messier 87, or M87, showed a ring of red, yellow and white surrounding a dark center. This is known as the black hole's shadow or silhouette. Project scientists looked for a ring of light around an area of darkness representing the black hole. As a result, it is difficult to see them. Their gravitational pull is so powerful that nothing, not even light, can escape. Sagittarius A* has 4 million times the mass of our sun and is located about 26,000 light-years from Earth.ДЄ light year is the distance light travels in a year, about 9.5 trillion kilometers.Д«lack holes are extremely dense. The EHT in 2019 revealed the first-ever photo of a black hole that is at the heart of a different galaxy. The international group behind the Event Horizon Telescope, EHT, project released the image. The University of ArizonaвЂ™s Feryal Ozel called the black hole вЂњthe gentle giant in the center of our galaxyвЂќ while announcing the new image. The mysterious object вЂ“ called Sagittarius A* - or SgrA* - is only the second black hole to be imaged. On Thursday, scientists released the first image of the very large black hole at the center of our Milky Way galaxy.
