3D map of 1.3 million quasars created using Gaia space telescope data aids in studying universe's expansion, dark matter, and cosmic web.
Astronomers have created a 3D map of over 1.3 million quasars, which are the cores of active galaxies powered by supermassive black holes. This map, which covers the largest-ever volume of the universe, uses data from the European Space Agency's Gaia space telescope. The new map offers a three-dimensional view of the largest-ever volume of the universe, giving astronomers a valuable tool to study the universe's expansion, dark matter, and initial density fluctuations that seeded the cosmic web.
