Cosmological simulations say that such an alignment should not happen, with a probability of less than 0.3%. Our neighboring Andromeda Galaxy (Messier 31, or M31) appears to sport a lopsided ...

Spanning approximately 220,000 light-years across, the Andromeda Galaxy is the largest galaxy of the Local Group, which also contains the Milky Way. Miguel Claro is a professional photographer ...

Specifically, all but one of Andromeda's satellites lie within 107 degrees of the line pointing towards the Milky Way, a region covering only 64% of the host galaxy's surroundings. Until now, it ...

The photo does appear to feature the Andromeda galaxy and a few of its smaller neighbors. However, according to Svoboda, they aren't in the right spot in the sky. Using an online tool called ...

Our neighboring Andromeda Galaxy (Messier 31, or M31) appears to sport a lopsided arrangement of satellite galaxies that defy scientific models, stumping astronomers who are also trying to figure ...

The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal ...
