An encounter with a "ghost of a galaxy" is still haunting the Milky Way.

We live in the wreckage of an epic galactic collision, says study

Hard Knocks

Astronomers believe a past galactic collision with Antlia 2 is to blame for large ripples in the Milky Way's outer hydrogen gas disc.

And it could help us solve the mystery of dark matter.

A new high-res map yielded an unexpected discovery.

Scientists find mysterious star-forming factory in Milky Way

Stellar Discovery

Astronomers have discovered that one subregion of the Milky Way is far more efficient at star formation than the others — and they don't know why.

"As soon as we investigated this particular group of stars in more detail, we knew that we had found what we were looking for."

Scientists found a “river of stars” flowing through the Milky Way

Stellar Stream

New research has uncovered a stellar stream comprising 4,000 stars flowing through the Milky Way remarkably close to the Earth.

This stellar stream has been hiding in plain sight.

It turns out our galaxy isn't the flat disk we once thought.

The Milky Way is a lot more warped than scientists thought

Distinct Kink

A new 3D map of the Milky Way galaxy shows a different structure than scientists expected. It turns out the outer disk is all warped out of shape.

"We should not fear the supermassive black hole."

Galactic collision could fling our solar system into intergalactic space

Bad Trip

An upcoming galactic collision could wake the Milky Way's black hole and fling our solar system into intergalactic space, according to new research.
