The European Space Agency‘s Gaia satellite has provided the data for an extremely detailed map of the Milky Way—the most detailed one yet.
In a statement, the ESA’s director of science, Gunther Hasinger, said, “The observations collected by Gaia are redefining the foundations of astronomy.”
This map is an upgrade to the 2016 version, which included about 2 million stars on it. According to the researchers behind Gaia, this one is a “huge leap forward” and took almost two years of sky charting to make.
The updated data details where the stars are, what color and how bright they are.
