Color Differences between Clockwise and Counterclockwise Spiral Galaxies
  While spiral galaxies observed from Earth clearly seem to spin in different
directions, little is yet known about other differences between galaxies that
spin clockwise and galaxies that spin counterclockwise. Here we compared the
color of 64,399 spiral galaxies that spin clockwise to 63,215 spiral galaxies
that spin counterclockwise. The results show that clockwise galaxies tend to be
bluer than galaxies that spin counterclockwise. The probability that the color
differences can be attributed to chance is ~0.019.
