By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the galaxy's mass-weighted chemical abundances and age structure. This ...

In their study published Thursday in the journal Science, they showed that by measuring the distance between classical Cepheid variable stars within the galaxy, they could develop a three-dimensional ...

Here’s how it works. Most of the atoms in your body likely spent millions of years circling the Milky Way on a cosmic "conveyor belt" before returning to our galaxy prior to the solar system's ...

The materials that make up your body are intergalactic voyagers that have existed beyond the limits of the Milky Way ... of life "took the long way around" the galaxy before coming together ...

Scientists may have uncovered the mysterious sources responsible for heating and sustaining the super-hot gas recently detected around the Milky Way — a phenomenon that has puzzled astronomers until ...

Using data from the APOGEE survey, astronomers from the Leibniz Institute for Astrophysics Potsdam, the University of Vienna and Paris Observatory have reconstructed the properties of ‘hidden’ stars ...

Galaxy clusters are home to many giant elliptical galaxies that have completed their growth and are not forming stars.

NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. A festive portrait of our Milky Way ...

Scientists have uncovered the existence of a binary star system close to the black hole near the center of the Milky Way galaxy.
