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. 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. A huge cosmic jet shoots out from the central black hole. 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.Ī light year is the distance light travels in a year, about 9.5 trillion kilometers.īlack 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 Arizona’s Feryal Ozel called the black hole “the gentle giant in the center of our galaxy” while announcing the new image.

You have the information that there is only one word on the billboard. Assume you are trying to take a photo of a billboard far away. The mysterious object – called Sagittarius A* - or SgrA* - is only the second black hole to be imaged. Related to the first image of a black hole, I explained my opinion in my first post: On the very first image of black hole: Part I Here Ill try to expand it with an example. It has a mass 6.5 billion times greater than Earth’s sun.On Thursday, scientists released the first image of the very large black hole at the center of our Milky Way galaxy. At the center of the galaxy is a supermassive black hole. Over several days in April 2017, each piece of equipment centered on a galaxy 55 million light years away from Earth. Here it is."ĭoeleman explained that the image resulted from a combined effort involving all eight of the EHT radio telescopes working at the same time. We have seen and taken a picture of a black hole. "We are delighted to be able to report to you today that we have seen what we thought was unseeable. Harvard University scientist Sheperd Doeleman leads the EHT project. The telescopes are part of the international Event Horizon Telescope (EHT) project.

A supermassive black hole with millions to billions times the mass of our sun is seen in an undated NASA artist's concept illustration.īut scientists say they were able to produce the new image from data collected from a series of radio telescopes around the world.
