Article Photos: Astronomers turn to 'crowdsourcing' for star hunt 1/3

This image provided by NASA shows the immense Andromeda galaxy, also known as Messier 31, captured in full in this new image from NASA's Wide-field Infrared Survey Explorer, or WISE. Astronomers are  looking for thousands of Internet volunteers, to identify and count clusters of stars of the Andromeda galaxy. Astronomers from Utah to Europe say it would take them too long to study that many images and they need help. (AP Photo/NASA)
