Video reveals that there is a huge black hole at the center of our galaxy, which is home to our solar system.
It is a splendid achievement achieved by the collective intelligence of the world, including our scientists.

The black hole in the movie boasts tremendous dynamism and splendor.
However, this appearance is only a product of the imagination.
Black holes cannot be seen because their gravity is so strong that they absorb even light.
But for the first time, a black hole at the center of our galaxy has been detected.
They succeeded in imaging the boundary zone where energy is released when matter is sucked into a black hole.

It was discovered in the constellation Sagittarius, 27,000 light-years from Earth.
It is the closest black hole observed by mankind.
Its size is also not large at 23.5 million km, which is about the distance from the Sun to Mercury.
This is a favorable condition for digging up the identity of black holes, which are still unknown.
Eight radio telescopes distributed from Greenland to Antarctica were connected to create an Earth-sized virtual telescope that allowed us to take images.
Over 300 scientists from 80 institutions around the world participated, and 9 of us also contributed.

Humans first photographed a black hole in 2019, three years ago.
The research team has revealed the black hole at the center of the galaxy M87, 55 million light-years from Earth.
