Scientists believe that on large scales the Universe is isotropic (the same in all directions). Thus, from our perspective, half of all spiral galaxies should spin clockwise, and half counter-clockwise. A recent analysis of the spin of spiral galaxies confirms this. read more

When we run simulations on supercomputers of galaxies forming it's pretty normal for two simulations of the same galaxy to have the same properties but for the spin to be a different direction, thanks to the chaotic motion of matter in the universe. read more
