Astronomers have discovered the smallest dwarf galaxy ever seen. It is a mystery how the satellite galaxy of Andromeda survived the blistering conditions of the early universe.

Their research was published in The Astrophysical Journal Letters on March 11. Andromeda XXXV is what astronomers term an ...

One of the great places to look for dwarf galaxies is the halo of the Andromeda galaxy (also known as Messier 31, or M31 for short), due to its relative proximity. UNIONS is so far the deepest ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

A Swarm of Dwarf Galaxies Buzz Around Our Milky Way's Twin Imagine the Milky Way and Andromeda as two massive aircraft ...

Andromeda is the bright spindle-shaped object at image center. All the dwarf galaxies seem to be confined to a plane, all orbiting in the same direction. The wide view is from ground-based ...

NASA's Hubble Space Telescope has uncovered 36 new dwarf galaxies around Andromeda and ongoing star formation within them, contradicting previous theories. They appear to undergo unique evolution ...

Andromeda, could change how we think about cosmic evolution. That's because dwarf galaxies this small should have been destroyed in the hotter and denser conditions of the early universe.
