Using artificial intelligence, astronomers mapped out the birthplaces of stars in the galaxy. In this respect informs Osaka University.
Stars are formed from the fusion and contraction of clouds of gas and dust in space. These molecular gases are so sparse and cold that they cannot be seen with the human eye, but they emit weak radio waves that can be observed with radio telescopes. There is a lot of matter in front of and behind these molecular clouds when viewed from Earth, and these overlapping features make it difficult to determine the distances and physical properties of the clouds.
Dr. A research team led by Shinji Fujita has detected approximately 140,000 molecular clouds passing through star formation in the Milky Way galaxy. This was done based on molecular gas data obtained with the Nobeyama Radio Observatory’s 45-metre telescope. Using artificial intelligence, the research team estimated the distance to each of these molecular clouds, determined their size and mass, and marked them on a map. According to the authors, this map is the most detailed map to date and covers the first galactic quarter.
In the future, since the southern constellations are not visible from Japan, the authors plan to supplement this map with data from other telescopes. Scientists hope this data will help build a more accurate model of the evolution of the universe and the birth of stars.
Earlier astronomers discovered Two giant exoplanets 353 and 524 light-years from Earth.
