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 ...
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, ...
A trio of astrophysicists with Harvard and Smithsonian's Center for Astrophysics has found via computer modeling that the likely reason for the warp and flare of the Milky Way galaxy is a tilt of the ...
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 ...
TROY, N.Y. – Heidi Jo Newberg, associate professor of physics at Rensselaer Polytechnic Institute, and Brian Yanny, an astrophysicist at Fermi National Accelerator Laboratory, who are leading a team ...
In the 20th century, it was ascertained that the sun lies approximately 26,000 light-years from the center of our galaxy, the ...
For decades, irregular gaps and kinks in stellar streams were astronomy's most reliable fingerprint for dark matter clumps.
September may be a good time to catch a sight of the Milky Way's center while it's still easily visible in 2026 across the US ...
