Earth is rushing to the most terrible “monster” of the Milky Way?

A recently published Japanese study found that the distance between Earth and the supermassive black hole Sagittarius A * shrinks by 1,900 light years.

Japan’s VERA project, using an astrophotometric instrument based on radio data, recreated our model of the Milky Way galaxy and mapped many of its objects in detail.

According to Sci-News, this new map has enabled the re-positioning of the Solar System, which includes our planet, measuring the distance between the Earth and the black hole at the center of the Milky Way as 25,800 light years, 1,900 light-years closer than the International Astronomical Union (IAU) figures published in 1985!

As many previous studies have shown, contrary to the traditional name “Milky Way”, based on an image of a huge bright star band across the Earth’s sky, our Milky Way is actually a spiral galaxies with the center of a “super monster” black hole named Sagittarius A *. Even though the true form of the galaxy has been known for a long time, its mapping is extremely difficult because we cannot get an overview of a galaxy that we are inside.

According to a publication in the Publications of the Astronomical Society of Japan, VERA uses an indirect approach: observing objects near Sagittarius A * to describe the structure and movement of the Milky Way. There are many telescopes located in Japan, Korea and China involved in this work.

VERA also detects that the Sun is moving at 227 km / s, which is 220 km / s faster than the officially recognized value.

It is still unclear whether the huge error in the distance between Earth and the “super monster” black hole after 35 years is due to the movement and change of the world itself, or the estimation of old astronomical tools. not exactly.
