The Milky Way has just been reconstructed in unprecedented detail, with artificial intelligence helping astronomers track the motions and histories of roughly 100 billion stars inside a single digital ...

Astronomers have finally identified where the Milky Way’s star-making activity fades, uncovering a long-sought boundary in ...

A new rotation curve analysis of the Milky Way reveals that conventional axisymmetric mass models cannot fully reconcile both photometric profiles and observed stellar motions. By modeling stellar, ...

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

The dark matter distribution of a Milky Way mass halo in a Lambda-cold dark matter (LCDM) cosmological simulation. This is the highest resolution simulation of a MW-mass dark matter halo ever ...

Spread the loveThe mysteries of our Milky Way galaxy continue to captivate astronomers and space enthusiasts alike, but recent findings challenge long-held beliefs regarding its formation. A ...

Our most massive satellite galaxy, the Large Magellanic Cloud (LMC), has been the center of a heated debate in the astrophysics community over the last few years. That debate centers on whether this ...

The Milky Way galaxy, comprised of billions of stars, will be visible in the night sky until the end of May, particularly between the last quarter moon (May 20) and the new moon (May 30). Light ...

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...
