The Andromeda Galaxy, our closest galactic neighbor, just 2.5 million light-years away, has long captivated astronomers with ...

The universe is far bigger and more interconnected than we can truly comprehend. Its scale is mind-bending. Driving around ...

Predictions are uncertain, but the solar system may be pushed farther from the galactic core or even ejected entirely from the new galaxy.

The Andromeda galaxy is the most distant object in the sky that you can see with your unaided eye. It's also on a collision course with our Milky Way.

Shockingly Tiny Galaxy Near Andromeda Is Just One-Millionth the Size of the Milky Way The fully formed galaxy is remarkably teeny, raising new questions about how galaxies emerge and evolve.

Solar systems will orbit around the galaxy's core — just like our system completes an orbit around the Milky Way every 240 million years —and aren't pulled into one another as galaxies merge.

Am astrophotographer has now unveiled the most breathtaking photo of the Andromeda galaxy we've ever seen, and he took it from his backyard.

The awe-inspiring distances of the cosmos are hard to visualise, so how can we be certain we are measuring them correctly?

A collision between our Milky Way galaxy and the neighboring Andromeda galaxy, long considered inevitable, may be in question, astronomers say.

Astronomers have long believed that our Milky Way will eventually collide with the Andromeda galaxy. A new study suggests that we might escape that fate. The spiral Andromeda galaxy is our closest ...

All but one of Andromeda's satellite galaxies were found to be pointing right at us. According to our best models, that shouldn't be the case at all.

THE Milky Way may have already commenced its ill-fated collision with a neighboring galaxy – and scientists predict this could fling the Solar System into deep space. Our galaxy is classified… ...
