Stargazers may catch a cosmic light show this Fourth of July weekend when the Milky Way appears in the night sky across the ...

"We find that the next most massive Local Group member galaxies — namely, M33 [Triangulum] and the Large Magellanic Cloud — distinctly and radically affect the Milky Way-Andromeda orbit," they ...

Both the Milky Way and the Andromeda galaxies (M31) are part of what's known as the Local Group (LG), which also hosts other ...

Another of the local group galaxies in the collection is NGC 3109, seen below, which is also 4 million light-years away — but, this time, in the Hydra constellation.

After factoring in the gravitational pull of Local Group galaxies and running 100,000 simulations using new data from the Hubble and Gaia space telescopes, the team found there is about a 50% ...

This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is ...

Scientists previously predicted the pair of galaxies would merge in about five billion years. Now, research suggests that ...

Astronomers have long thought that the Milky Way is headed for an inevitable crash with its neighbor, Andromeda. But a new ...
