Compiling a new map of the Milky Way Galaxy, the scientists drew attention to the fact of the location of the Solar System. It is located at different coordinates than previously thought. The Milky Way is not only located closer to the center and to the supermassive black hole in it, but also rotates much faster than the astronomers believed.
At the same time, they note that humanity has nothing to worry about, the danger of a black hole being absorbed by the Earth does not threaten, and the map of the Milky Way was previously designed in such a way as to more accurately determine the location of our planet.
A review of the data demonstrates how difficult it is to map the Galaxy in its three internal changes. This complexity has long disturbed the understanding of phenomena occurring in space. Mapping the 2D coordinates of stars and other space objects is relatively easy.
But determining the distance to these objects is much more difficult. The distances are important because they allow to calculate the internal brightness of objects.
One example is the calculation of the red giant Betelgeuse’s location. It turned out to be much closer to the Earth than all previous calculations showed. Another object is the star CK Vulpeculae that exploded 350 years ago. It was located much further than science had previously calculated.
And new data about it require a new explanation. New calculations are carried out using the VERA radio astronomy survey. It is a whole complex of radio telescopes installed in Japan. They combine data to produce images of a specific resolution, exactly the same as a telescope with a length of 2,300 kilometers.
The complex has the same technical principle as the Event Horizon telescope that produced the first ever direct image of a black hole's shadow.
