Furthermore, the scientists concluded that the disk of this spiral galaxy will grow over time, with the birth of new stars.
Researchers from the National Astronomical Observatory of Japan have developed a map of the Milky Way, using information obtained over the past 15 years from the VERA radio astronomy project.
The specialists estimated the position of the Earth relative to the black hole at the center of the spiral galaxy where the solar system is located, called “Sagittarius A *”. According to astronomers, in 1985, our planet was 27,700 light-years from this very compact and bright radio source, while recent data already place it at 25,800 light-years away.
Scientists have explained it The Earth accelerated by 7 kilometers per second and approached the supermassive black hole about 2,000 light years. However, they assured that “there is no reason to worry” and added that “this does not mean that our planet is sinking towards the black hole”.
For their part, specialists from the European Space Agency (ESA) have created their own 3D map of the Milky Way, using data from the Gaia probe.
Experts said that in the past two years they have managed to obtain new information on around 200 million stars and currently have. detailed data on over 1.8 billion space objects. “The new data from Gaia has allowed astronomers to track the various oldest and youngest star populations to the edge of our galaxy, the galactic anticenter,” they noted in a statement released Thursday.
After creating computer models of the galaxy, scientists concluded it the disk of the Milky Way will grow with time, when new stars are born. “The new data allows us to see the remains of the 10-billion-year-old disk and then determine its smaller extent than the current size of the Milky Way disk,” they added.
