A Hubble Space Telescope study takes a close look at the dwarf galaxies surrounding Andromeda. Surrounding the Andromeda galaxy, three dozen tiny galaxies aren't behaving the way scientists expected.

Also known as M31, Andromeda is the Milky Way’s closest major galaxy, measuring roughly 152,000 light years across, with almost the same mass as our home galaxy. The younger James Webb Space Telescope ...

This is the largest photomosaic ever assembled from Hubble Space Telescope observations. It is a panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away. It took over ...

Galactic neighbor: NASA's Hubble Space Telescope has captured a massive panoramic view of the neighboring Andromeda galaxy (Messier 31), which is situated just over 2.5 million light-years away from ...

In a landmark study, scientists using NASA’s Hubble Space Telescope have mapped the immense envelope of gas, called a halo, surrounding the Andromeda galaxy, our nearest large galactic neighbor.

The Hubble Space Telescope has provided some of the most beautiful visuals of the cosmos over the years, and this year was no ...

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 study ...

The Andromeda galaxy is the galaxy next door, a very faint, fuzzy thing in the night sky, larger than a full moon. Textbooks claim it’s visible to the naked eye. Most of us have never noticed it. Too ...

NASA recently released images of the Andromeda galaxy, an "enticing empire of stars" that can be seen with the naked eye if weather conditions are just right. About 100 years after astronomer Edwin ...
