The Event Horizon Telescope encompasses the Global Network of Radio Telescopes. It observes supermassive black holes with the help of very long baseline Interferometry Stations.
Earlier it has also observed m87 star. Now it has observed Sagittarius A which is in the center of the galaxy. According to astronomers, this black hole is 4 times bigger than our Sun.
There is so much gravity inside a black hole that it can pull light inside itself. If light comes in contact with it, then it will not be visible. Black holes are born from the death of stars.
When a star gets too old, that’s when it ends. So somewhere from the union of stars, a black hole with Super Gravity is formed. But we cannot see this black hole with our own eyes.
The Event Horizon Telescope Facility shared with the public the first picture of the black hole at the heart of our galaxy at a press conference.
This Event Horizon Telescope Facility was created in 2019 by a collaboration of 300 researchers. Earlier it has also discovered the m87 black hole.
This new Sagittarius A black hole is 27000 light years away from us. But SGRA is much smaller than M87. The swirling of gas around it takes only a few minutes to revolve around its orbit.
But it takes at least 8 to 10 hours to get a clear picture of this black hole. Because this object does not change much. The focus of this group is on observing only and only black holes. It took the first picture of a black hole in 2019.
Giving information, Joseph, who is a professor of physics, said that this black hole is at the center of the place where we live. Peter Galison, Director of the Harvard black hole initiative, They say that this is our supermassive black hole.
Here let us tell you that this black hole named Sagittarius A-star is also known as Sgr A*. This dark black hole is surrounded by yellow and red rings. Members of the EHT project held this conference at 9am at the National Press Club in Washington DC.
