A feature on citizen science for the Guardian Online has included a profile of the highly successful Zooniverse projects. The feature details how Zooniverse began in 2007 with Professor Chris Lintott‘s Galaxy Zoo project, which exceeded all expectations with 100,000 citizen scientists signing up to classify galaxies. Many important discoveries, including a new planet, were made by these volunteers. Galaxy Zoo was so popular that it was developed into Zooniverse, where over one million volunteers are registered and anyone can get involved in contributing to real research in space, climate, nature, humanities and biology projects. To get involved in citizen science, visit the Zooniverse site to register and choose from the exciting range of current projects.
