larger black hole
black hole: black hole The research by scientists from Columbia University, Harvard University and several colleges in Chile was published last week in the journal Nature .
Researchers have often suspected that black holes accumulated in the center of galaxies, but until now they had only found one in the Milky Way. Dubbed Sagittarius A by NASA, the hole has a mass four million times that of the sun.
A supermassive black hole has disappeared whose weight is about 100 billion times more than the weight of the Sun. Scientists have lost their sweat in finding this black hole. The US space agency NASA is using NASA’s Lunar X-ray Observatory and the Hubble Space Telescope to find this missing black hole, but it is not known yet. For your information, tell us that black hole is the place in space where no law of physics works. Its gravitational field is so powerful that nothing can escape its stretch. Even light cannot go out after going into it.
Sagittarius A is surrounded by gas and dust, which can lose their energy and become black holes. Other black holes could also be held captive by the supermassive one.
The black hole
disappeared in the center of Abell 2261 The black hole galaxy (galaxy) Coulter should have been in Abell 2261 but it is not here. The distance of the galaxy cluster Abell 2261 is about 2.7 billion light years from Earth. Explain that the distance of one light year is 9 lakh crore kilometers. Light years are used to measure the distance between stars and galaxies.
At the center of each galaxy is a massive black hole that weighs billions more than the Sun. The black hole in the center of our Galaxy i.e. Milky Way is called Sagittarian A * (Sagittarius A *). It is 26,000 light years away from Earth. Scientists are analyzing data from 1999 to 2004 to find the black hole at the center of Abell galaxy, but no evidence of a black hole has yet been discovered.
Black holes may merge together
; A team at the University of Michigan in the United States says that Abell 2261 may also cause it to move out of the center of the galaxy because it is not a black hole. According to data from NASA Lunar Observatory for 2018, the formation of two smaller galaxies would have led to the formation of a larger galaxy, due to which the black hole is not visible.
Recoiling Black Holes
When two black holes join together, they create gravitational waves that move at the speed of light and can squeeze everything in their path to create a stretch. According to the theory of gravitational waves, during such a merger, when the amount of waves generated in one direction is greater than the waves in the other direction, new large black holes can be sent in the opposite direction from the center of the galaxy. This is known as the “recoiling” black hole.
However, so far scientists have not found any evidence for the recoiling of the black hole. Also, it is yet to be ascertained whether the supermassive black holes can join together and release the gravitational waves. For your information, let us know that so far only small black holes have been confirmed to be interconnected and if the University of Michigan’s hypothesis about this missing black hole is true then it will be seen as a major success of astronomy .
“It’s one of the most fascinating places in the universe,” Dr. Kaya Mori, associate research scientist in the Columbia Astrophysics Laboratory, told Observer. “It’s the most crowded region with lots of stars, gas and black holes. Everything is there.”
The new mission used 12 years of data from NASA’s Chandra X-ray Observatory telescope. It focused on black holes which emit radiation when they interact with orbiting stars.
About five percent of holes feed on stars by sucking the starlight into the shadows. This consumption produces a glowing disk of hot gas around the black hole that can be detected by the Chandra telescope.
The initial observations detected 12 black holes which paired up with stars. Each of these holes is about 10 times the mass of the sun.
This small number of new holes is significant on its own because scientists have only found evidence of about 60 black holes in the entire galaxy.
But there’s much more where that came from: researchers extrapolated that there are 300 to 500 more black holes paired with stars in the region and about 10,000 isolated holes around Sagittarius A.
