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 ...

Using variable stars as distance markers and the giant telescope on Mount Wilson, Edwin Hubble (then a young and little-known astronomer) was able to show that the Andromeda Nebula was over a ...
