First-ever image of a black hole in the center of the milky ways revealed by scientists.
This is the giant
black hole in the center of our own galaxy, the Milky Way, and scientists have
now released a picture of it for the first time. This black hole, called
Sagittarius A, is 4 million times larger than our Sun. The image you have in
front of you is a black hole in the middle of the black hole and the light is
reflected from the extremely hot gases around it. These gases are in
circulation due to their extreme gravity. This circle is as wide as the orbit
of the planet Mercury around our Sun, i.e. about 60 million kilometers.
Fortunately, it is 26,000 light-years from Earth, so we will never be in danger.
This photo was taken and released by Event Horizon Telescope, an international organization.
If our eyes could see the radio waves, this black hole would look something
like this up close. Earlier in 2019, the same team released a picture of a
black hole in the center of another galaxy M87. That black hole is a thousand
times larger than this black hole and six and a half billion times larger than
our Sun.
"This new image
is special because it is our own huge black hole," said Professor Hino
Fock, a European scientist at the Event Horizon Telescope Project. The
Dutch-German scientist from the University of Radbod in the Netherlands told
BBC News: "It's in our own backyard and if you want to understand black
holes and how they work, this black hole is for you. Will tell, because we can
study it carefully. What is a black hole? A black hole is an area in space
where matter becomes infinitely dense. The gravity here is so great that
nothing, not even light, can escape. Black holes are formed by the explosive
endings of the lives of some very large stars. Some black holes maybe billions
of times larger than our Sun. Scientists cannot say for sure how these black
holes at the center of galaxies came to be. But it is clear that they provide
energy and keep the galaxy moving, and affect its evolution. Presentational gray

This black hole,
26,000 light-years from Earth, may appear smaller than the tip of a needle in
the sky due to its distance, so scientists need a much thinner resolution than
a normal telescope to capture such a target. Event Horizon Telescope Network
used a technique called Very Living Baseline Interferometry (VLBI). Not a single
telescope was used, but eight radio antennas located at great distances from
each other were interconnected to produce results similar to a telescope as
large as the size of the Earth. Mystery of Existence from Non-existence: What
existed before the Big Bang?Interesting story of the mysterious existence and
evolution of the largest black holes in the universe from the taunts of the
parents to the death of the first child, what did Einstein suffer?Glamorous
images of galaxies that have never been seen before So the Event Horizon
Telescope got such a resolution that they could see, for example, a donut
placed on the surface of the moon. Nevertheless, with the help of atomic clocks
and state-of-the-art algorithms, supercomputers have been able to capture
images of many petabytes (one petabyte contains 1 million gigabytes) of data
for countless hours.

Since no light can
come out of the black hole itself, nothing but a black spot can be seen, but by
looking at the circle of bright matter (action disk) around it, scientists can
guess where the black hole is. located in. Blackhole The team unveiled the
image globally in seven simultaneous events. Extremely hot gases or plasmas in this
circle are circulating around the black hole at a much slower speed than the
speed of light. The brighter parts are probably where the matter is coming
towards us. Scientists are comparing the newly acquired image with existing
information in our physics about black holes. So far, they have found that it
is entirely in line with Albert Einstein's formulas for the theory of general
relativity. Scientists have long believed that there is a huge black hole in the
very center of our galaxy because, without it, it would not be possible to
predict the gravitational pull of the stars in the center at speeds of up to
24,000 kilometers per second.
