Our projects live within the 'Zooniverse' the home of Citizen Science on the web. Each is inspired by a science team who provide the initial ideas, the reassurance that what we're doing can make a real contribution and an audience who are willing to use the end result. We are working with a wide variety of partners, from classicists to climate scientists and ecologists to planetary scientists, but the following projects are now available:
Moon Zoo: 
Explore the Moon in unprecedented detail using images from NASA's Lunar Reconnaissance Orbiter Camera.
Galaxy Zoo: Hubble
The latest version of the original Zooniverse project. Help astronomers figure out how galaxies form and evolve by classifying their shape. Now with added Hubble galaxies.
Solar StormWatch: 
Help spot explosions on the Sun and track them across space to Earth. Your work will give astronauts an early warning if dangerous solar radiation is headed their way.
Galaxy Zoo Mergers:
A test case for more complicated modes of interaction, visitors are invited to compare simulations of mergers between galaxies with observation. By having many thousands of people run simulations, we can explore the vast parameter space more efficiently than with automated routines.
Galaxy Zoo Supernovae:
Help us to catch an exploding star. The task in this latest Galaxy Zoo project is to help us catch exploding stars - supernovae. Data for the site is provided by an automatic survey in California, at the world-famous Palomar Observatory.
Archived projects
Galaxy Zoo 2:
Galaxy Zoo 2 collected 60 million classifications in just over a year, taking a closer look at 250,000 galaxies. The first papers using this data set have now been published
Galaxy Zoo:
The project which inspired the CSA, Galaxy Zoo provides detailed classifications of galaxies according to their morphology. Galaxy Zoo has produced more than 15 papers in professional journals, and the team have been successful in biding for follow-up time on some of the world's most advanced telescopes, including the Hubble Space Telescope.
