A study by MIT physicists suggest the Milky Way’s gravitational core may be lighter in mass, and contain less dark matter, than previously thought. By clocking the speed of stars throughout the Milky ...

Thanks to the latest Gaia satellite catalog from the European Space Agency (ESA), an international team led by astronomers from the Paris Observatory–PSL and the CNRS has achieved the most accurate ...

A slowly rotating stellar halo was the clue to a major and unknown event in the Milky Way's history that saw the spiral disc flip over by more than 90 degrees.

There is a lot we have yet to understand about the center of the Milky Way—could it be due to a mass of invisible dark matter? Reading time 3 minutes Astronomers have yet to fully grasp the Galactic ...
