Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum plaguing the standard model of cosmology.

Scientists have long thought the Milky Way galaxy would someday collide with its closest neighbor, Andromeda. However, new research suggests the future of our cosmic home is more uncertain than ...

Astronomers have uncovered shocking evidence that one of the closest galaxies to our own is being torn to shreds by its neighbor. Located around 200,000 light-years from Earth, the Small Magellanic ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. Though the Milky Way is generally always visible from Earth, certain times of year are better for ...

The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

Velocities of massive star candidates within the SMC shown as vectors. The colors of the arrows represent the direction of motion. Relative to the LMC, located at the bottom left of the image, most ...

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 ...

For decades, scientists have used the Milky Way as a model for understanding how galaxies form. But three new studies raise questions about whether the Milky Way is truly representative of other ...

A successful builder by day and traversing the sky by night, Isaac Roberts took the first clear photograph of Andromeda, the ...

What you're looking at when the Milky Way is visible is the bright center of our galaxy with billions of stars. Because visibility from Earth depends on the latitude, the further south you go, the ...

The Milky Way is our home galaxy with a disc of stars that spans more than 100,000 light-years. While the Milky Way is generally always visible from Earth, certain times of year are better for ...
