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 is also known as Messier 31. It is a spiral galaxy located about 2.5 million light-years from Earth. On a clear night, some stars of the galaxy can be seen from Earth.

A collision between our Milky Way galaxy and its largest neighbor, the Andromeda galaxy, predicted to occur in about 4.5 billion years, has been anticipated by astronomers since 1912.

Recent astronomical observations have confirmed that the Andromeda Galaxy is on a collision course with our Milky Way, signaling the beginning of an epic cosmic event. Located 2.5 million light ...

The spiral Andromeda galaxy is our closest neighbor, sitting 2.5 million light-years away. The consensus was that after circling ever closer for billions of years, the two galaxies would collide.

As luck (or, in fact, proximity and gravity) would have it, astronomers soon figured out that Andromeda is likely on a collision course with our own galaxy. This is nothing to worry about of ...

When will the Milky Way collide with the Andromeda Galaxy? It's a common question because, for many years, astronomers have theorized that the two largest spiral galaxies in our cosmic ...

The researchers observed Andromeda XXXV with the Hubble Space Telescope. “This type of galaxy was only discoverable around one system, the Milky Way, in the past,” Bell said.

While the Triangulum galaxy’s gravitational influence conspired to bring the Milky Way and Andromeda together, the LMC had a repellent effect. And when all four danced together, the odds of an ...

While they used the radial velocity of the larger galaxy to determine this, they didn't properly take Andromeda's transverse velocity into account, this new study claims.

Andromeda XXXV contains an estimated 20,000 Suns worth of stars and lies about half a million light-years from the center of the Andromeda Galaxy, or about three times the width of M31 itself.
