Participate in a Citizen Science Project with Zooniverse
According to the Zoomiverse website:
"The Zooniverse is the world’s largest and most popular platform for people-powered research. This research is made possible by volunteers — more than a million people around the world who come together to assist professional researchers. Our goal is to enable research that would not be possible, or practical, otherwise. Zooniverse research results in new discoveries, datasets useful to the wider research community, and many publications."
