Looking at today's APOD
http://antwrp.gsfc.nasa.gov/apod/ap080614.html
I found myself wondering on the relative proportions of clockwise and anticlockwise spiral galaxies that we observe from our vantage point on earth. Logically I would expect equal numbers? A bit of internet searching turned up:-
Referring to the GalaxyZoo project, a poster said:- "A
recent and ongoing study shows that the direction of the arms in spiral galaxies is uniformly distributed in 'all' directions. That is, no regions have been found with concentrations of clockwise or anti-clockwise rotating galaxies. A previous smaller study seemed to indicate that there was such a 'preference'. The larger study seemed to confirm that at first, but when presented with mirrored images, the 'preference' stayed the same. So it seems it was human error: a human viewer would have a preference in seeing a certain rotation when the image wasn't very clear. Careful analysis of the classification of regular and mirrored images shows no preference in either rotation."
So 50:50. Is that what you understand it to be?
