They write in the article:
The survey has revealed that the collections of millions of stars, dust, gas and planets in galaxies prefer to rotate anticlockwise from the viewpoint of an observer on Earth.
Traditionally astronomers have believed that galaxies would spin either clockwise or anti-clockwise in equal proportion. But these observations would seem to suggest that either a mysterious force is acting on them or that the universe is in some way lopsided.
I think this project was an incredible success, and a model for future endeavors in large-scale classification. Also, it was incredibly fun to participate in, as I got a host of cool galaxy images to download onto my computer for my screensaver.
