One of the mysteries of the universe, it was first discovered that the black hole, the closest black hole to Earth, is a spherical circle. Researchers at home and abroad have succeeded in observing through the gas cloud.

A photograph that confirmed Einstein’s theory of relativity.
This is the first black hole seen by humans.
A black hole in the galaxy M87, located 55 million years away at the speed of light, made possible by radio telescopes that use radio waves instead of light to observe celestial bodies.

However, the black hole in our galaxy, closest to Earth, has been veiled until now.
It was covered by a cloud of gas, making it difficult to observe.
However, following five years of analysis with a foreign research team, the Korea Astronomy and Space Science Institute has successfully penetrated this cloud and photographed the periphery of the black hole.
The radio telescope has found a formula that can remove only the scattering of light caused by gas clouds from the signals observed around the black hole.
The research team found that this black hole was observed in a circular shape, and the gas revolved around it like Saturn’s belt, and the axis of rotation was directed toward the Earth.

As more precise observations like the M87 black hole image will be possible in the near future, this study will be of great help in uncovering the secrets of our galaxy.
