Messier 31 , or M31 , appears to sport a lopsided arrangement of satellite galaxies that defy scientific models.

All but one of M31 's brightest 37 satellites are on the side of the Andromeda spiral that faces our Milky Way .

According to cosmology's standard model, these dwarf galaxies should be spread randomly around larger galaxies.

However, even the planes of satellites scientists have confirmed are difficult to explain.

Astronomers are aiming to determine motions for at least a dozen of M31 's dwarfs to high precision within another year or two with the release of the next dataset from the Gaia astrometric mission.

There likely remains many fainter, as yet undiscovered, satellite dwarf galaxies around M31 .

Cosmology’s standard model predicts there should be more dwarf satellites around both M31 and our Milky Way .
