Thanks for calling http://xhub.in.net/ Youjizz Between Feb. 2009 and April 2010, more than 83,000 Galaxy Zoo 2 volunteers of all different nationalities stared at online images amassed from the Sloan Digital Sky Survey. They answered questions about the distinguishing features of each galaxy, such as whether it had spirals, the number of spiral arms observed, or if it had bulges. All in all, the volunteers made 16 million classifications of 304, 122 galaxies, representing some 57 million computer clicks. That amount of work would take a single researchers about 30 years to complete, researchers said.
