Further studies predicted that Andromeda's eventual collision with our Milky Way was inevitable within the next 5 billion years — a process that would see our solar system catapulted to an outer ...

Scientists have predicted for a while now that the fate of the Milky Way galaxy will result in a collision with our neighboring Andromeda galaxy. Of course, we don’t expect that collision to ...

The European Space Agency's Milky Way-mapper Gaia has completed the sky-scanning phase of its mission, racking up more than 3 ...

In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy stands out as the most important nearby ...

If that’s the case, then the Milky Way and Andromeda, thought to be on a collision course in about four billion years, could already be interacting. The headline finding from the research is ...

Hubble revealed a universe of galaxies that existed beyond ours — but he couldn't have done it without a little help.

Younger stars tend to be born in the region of the galaxy called the thin disk, and tend to orbit the center of the Milky Way in roughly the same direction. Older stars, belonging to the region ...

Astronomers are celebrating the completion of a 2.5-billion-pixel panoramic picture of the entire Andromeda Galaxy. The team includes several UC Santa Cruz researchers who made significant ...

The Andromeda Galaxy, our nearest galactic neighbor, is a majestic spiral galaxy like the Milky Way. Let’s uncover some ...

Spur and gap features seen in Milky Way’s GD-1 stellar stream could be caused by a self-interacting dark matter subhalo. New research points to a dark matter subhalo as the architect behind the unique ...
