Galaxy Zoo

(crowdsourcing website to identify galaxy types from surveys)

Galaxy Zoo is an online project to classify the types of galaxies in large surveys. It was launched in 2007 to classify objects photographed by the Sloan Digital Sky Survey, displaying the object to the website-visitor, prompting for input as to whether the object appears to be elliptical or spiral as well as to the direction of the spirals. Tens of thousands of volunteers have classified millions of galaxies. Survey results have been published, interesting galaxies have been discovered, and updates of the project have been initiated: Galaxy Zoo 2, and more such crowd-sourced classification, in astronomy and also in other unrelated fields.
