The researchers used the distribution data inCarbon monoxide in the galaxy, collected by the 45-meter telescope of the Nobeyama Radio Observatory. Using AI, scientists estimated the distance to each of these molecular clouds and determined their size and mass.
As a result, researchers have created the mosta detailed map of the distribution of star-forming regions. So far, their work covers only the first galactic quadrant - one of the four sectors into which the Milky Way is conventionally divided.

Stars are formed from mergersmolecular gas and dust in space. These molecular gases are so rarefied and cold that they are invisible to the human eye, but they emit weak radio waves that can be observed using radio telescopes.
The difficulty lies in the fact that when observingThe Earth has a lot of matter in the background and in front of such areas, and these overlapping features make it difficult to determine their distance and physical properties such as size and mass.
The scientists plan to continue their work, in particular, supplementing their data with observations of the sky in the southern hemisphere to supplement data on other parts of the Milky Way that are not visible in Japan.
