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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Artistic representation of the Milky Way, where the innermost stars move at near relativistic speeds (defined as velocities that ...

The temperature difference is not subtle. One side of the Milky Way’s outer halo runs noticeably hotter than the other, a mismatch that has puzzled astronomers since it was measured.

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 ...

A dark matter signal that appears in one place but not another might look like a contradiction. This new study argues it may ...

Our Milky Way galaxy may not have a supermassive black hole at its centre but rather an enormous clump of mysterious dark matter exerting the same gravitational influence, astronomers say. They ...

Astronomers have proposed a theoretical model suggesting that the object at the centre of the Milky Way, widely identified as ...
