Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to ...

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current ...

Astrophysicists suggest our galaxy may lie inside a "cosmic void" - offering a new explanation for the universe’s conflicting ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, ...

Astronomers now believe the Milky Way’s “inevitable” collision with a neighboring galaxy is much less likely than originally thought.

What does the Milky Way look like? Sometimes, the billions of stars comprising our home galaxy appear especially vibrant during “Milky Way season” as the band arcs across the night sky.

Milky Way galaxy might not collide with Andromeda after all Astronomers ran 100,000 computer simulations using combined Hubble/Gaia space telescope data.

When the billions of stars comprising the Milky Way, our home galaxy, appear especially vibrant as the band arcs across the night sky, it’s a photo op ...

New data from NASA's Hubble Space Telescope has created uncertainty in the theory that the Milky Way and Andromeda will collide and merge.

Milky Way's chance of colliding with Andromeda? New study puts odds at 50-50 For this new study, the scientists relied on updated galaxy measurements to factor in the gravitational pull on the ...

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.

New data show a 50% chance the Milky Way won't collide with Andromeda. A merger with the Large Magellanic Cloud is far more likely.
