Earth is 2,000 light-years closer to the Milky Way's supersensitive black hole than previously thought

The new air map created by Japan’s National Astronomical Observer This indicates that the Earth is rotating rapidly, and that the supermassive black hole in the center of our galaxy is closer to 2,000 light years than previously thought.

In 1985, the International Astronomical Union announced that Earth is 27,700 light-years away from a black hole, named Dhan A. But a 15-year analysis by the Japanese radio astronomy project Veera found that Earth is actually only 25,800 light-years away. They also found that the Earth was moving at a speed of 7 km per hour beyond their belief.

The sound A * and similar black holes are called “supermassive” for a reason – they are Billions of times bigger Than the sun

But the NAOJ said there was no need to worry, as the latest figures did not indicate that the planet was “sinking into a black hole.” This literally means that there is now a “better model of the Milky Way galaxy”.

Using the Vera Astrometry Catalog, scientists mapped a position and motion that centered on the Milky Way galaxy and the objects that lived inside it. The Veera Astrometry Catalog was published earlier this year and contains data for 99 objects.

The position shows that the Earth revolves around the galactic center where the black hole is located, 227 km / s. Astronomers actually thought that the orbit was at a speed of 220 kilometers per hour.

“Because the Earth is located inside the Milky Way galaxy, we cannot go back and see what the galaxy looks like from the outside,” the NAOJ said in a press statement. “Astrology is an important tool for understanding the position of objects and accurate measurements of movements, the overall structure of the galaxy and our place in it.”

Vera, the longest baseline interferometric exploration of radio astronomy, was built in 2000 and uses interferometry to collect data collected from radio telescopes throughout Japan. Through the project, scientists will be able to develop resolutions similar to telescopes with a diameter of 2,300 kilometers, which is “theoretically sharp enough to solve United States money placed on the surface of the moon,” the NAOJ said.

Scientists at Naoze are hoping to gather data on more objects, focusing on people close to Dhan A *.
