Galaxy Zoo
Galaxy Zoo volunteers are asked to judge from the images whether the galaxies are elliptical or spiral and, if spiral, whether they are rotating in a clockwise or anti clockwise direction. The images were taken automatically by the Sloan Digital Sky Survey using a digital camera mounted on a telescope at the Apache Point Observatory in New Mexico, United States. It is hoped this census will provide valuable information about how different kinds of galaxies are distributed, allowing scientists to determine whether existing galactic models are correct. It is an example of citizen science.
