A recently published Japanese study found that the distance between Earth and the supermassive Sagittarius A * black hole decreases 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 allowed the repositioning of the solar system, which includes our planet, measuring the distance between Earth and the black hole at the center of the Milky Way at 25,800 light years, 1,900 light years closer than data from the International Astronomical Union (IAU) published in 1985!
As many previous studies have shown, unlike the traditional name “Milky Way,” based on the image of a band of giant bright stars across the Earth’s sky, our galaxy spirals galaxies with the center of a “super monster” black hole named Sagittarius A *. Even though the true shape of the galaxy has been known for a long time, its mapping is extremely difficult because we cannot get a big picture of a galaxy we are in ourselves.
According to a publication in the publications of the Astronomical Society of Japan, VERA uses an indirect approach: the observation of objects near Sagittarius A * to describe the structure and motion 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 not yet clear whether the enormous error in distance between Earth and the “super monster” black hole after only 35 years is due to the movement and change of the world itself, or to the estimate by d ‘old astronomical tools not exactly.
