The Andromeda Galaxy (M31) is one of the most fascinating objects in our night sky and is located relatively close to the Milky Way, making it an important focus for astronomers. This spiral galaxy, ...

A new composite image of the Andromeda Galaxy is offering an unprecedented view of our closest spiral galactic neighbor.

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 new image from NASA composed of different wavelengths created a stunning image of Andromeda. “This new image of M31 is released in tribute to the groundbreaking legacy of Dr. Vera Rubin, whose ...

As Hubble already discovered, galaxy movements within the Local Group don’t show the same cosmological spectral shifts as galaxies beyond. In fact, the spectral shift of the spiral galaxy M31 ...

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

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.

A view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away. Located 2.5 million light-years away, the majestic Andromeda ...

This is a wide-angle view of the distribution of known satellite galaxies orbiting the large Andromeda galaxy (M31), located 2.5 million light-years away. The Hubble Space Telescope was used to ...

Hubble worked hard, taking images of spiral nebulae every clear night and looking for the telltale variations of Cepheid variables. By the end of 1924, he had found 12 Cepheids in M31.
