It is hoped that this will help to learn more about the distribution of stars, gas and dust throughout the disk of the Milky Way.
Astronomers have created a map of the Galaxy with 3.32 billion stars and other objects. This was reported by the press service of the US National Laboratory of Optical and Infrared Astronomy.
It was noted that an international team of scientists used images from the 570-megapixel DECam astronomical camera.
“Combining our images with those from the automated Pan-STARRS telescope allowed us to obtain a complete 360-degree view of the entire disk of the Milky Way, including a large number of very dark star. The resulting catalog allows us to map and study the three-dimensional structure of the Galaxy, as well as the distribution of dust accumulations and the stars within it with incredibly high precision ,” said Andrew Saijari, a researcher at Harvard University in the United States.
It is known that the DECam astronomical camera was created in 2013 as part of the Dark Energy Survey project to search for traces of the existence of dark energy. Its ultra-high sensitivity helped in 2016 to identify one of the most distant dwarf planets in the solar system, 2014 UZ224, whose year lasts about 1139 years, using DECam images.
Now, astronomers analyzed the images it received and identified about 3.3 billion stars and other objects, the existence of which was subsequently confirmed using images and scientific data obtained by the automated Pan-STARRS telescope and of the GAIA orbiting observatory.
Recall that earlier the Hubble Space Telescope took a picture of the open star cluster NGC 1858 in the satellite galaxy of the Milky Way, which is located at a distance of about 160 thousand light years from Earth and contains many large stars that shine brightly in the middle. of the picture.
