Tokyo: New information about Earth and the Black Hole has been revealed. Scientists say the theory was initially different from the theory of the distance between Earth and the black hole. In this regard, a map has been published by the Japanese radio astronomy project VERA. This shows that the Earth is closer than before to the supermassive black hole in the center of the Milky Way.
It has also been found in research that our solar system is also moving rapidly around this black hole named Sagittarius A *. Its speed is about 7 km / s. According to a new project prepared by VLBI Exploration of Radio Astrometry, the supermassive black hole is now 25,800 light years from Earth, whereas in 1985, the International Astronomical Union described it as 27,700 light years.

Project started in 2000
In an official statement, the National Astronomical Observatory of Japan reported that Japanese space researchers started the project to measure three-dimensional velocities and space structures in the Milky Way in 2000 using very long-base interferometry. (VLBI). According to NASA’s Jet Propulsion Laboratory, space geodetic technology collects signals from space from an astronomical radio source. 15 years of observations were compiled using this technique. Scientists at the Japanese lab mapped the three-dimensional speeds and spatial structures of the Milky Way and the position of the Earth, and the map was published in the VERA Astrometry Catalog, which also contains data for 99 other objects. astronomical.
Much bigger than the sun
This supermassive black hole is known as Sagittarius A * or Sgr A *. Its size is 4.2 million times the size of the Sun. It was first discovered by Reinhard Genzel and Andrea Ghez using NASA’s Chandra X-ray Observatory. The goal of VERA is to get more details about the objects around the supermassive black hole.
Creating a two-dimensional map is easy
Scientists say that since our solar system does not penetrate inside Sagittarius A *, there is nothing to worry about. Scientists have prepared this map on the basis of three-dimensional speed, which is the most difficult task. It was the biggest challenge in making an accurate map of the Milky Way. It is easy to map space stars and other objects at the two-dimensional level, but it is difficult to estimate the distance between these objects.
