Citizen Science: Discover Space

Find projects where you can participate in space discoveries

Get involved in the research and participate with the teams analyzing space data.

This page offers a list of citizen science projects using data in the Mikulski Archive for Space Telescopes (MAST).

The number of space-based citizen science projects is always changing. Please check back for updates and new listings.

Star Date: M83

Help us find the age of star clusters in the Southern Pinwheel Galaxy, also known as M83.

We're working to understand how and when stars form and disperse into a galaxy. Most stars form in clusters, and then eventually spread out. Young and old clusters differ in characteristics, making it possible to estimate ages based on their appearance.

You'll examine a series of star clusters captured in a new Hubble Heritage image of M83, and identify the features that help us pinpoint their age.

Planet Hunters

With your help, Planet Hunters is looking for planets around other stars.

Find new planets by looking at how the brightness of a star changes over time.

Such changes observed by NASA's Kepler spacecraft can indicate the presence of transiting planets.

Galaxy Zoo: Hubble

How do galaxies form?

NASA's Hubble Space Telescope archive includes hundreds of thousands of galaxy images.

To understand how these galaxies, and our own, formed we need your help to classify them according to their shapes — a task at which your brain is better than even the most advanced computer.

The Andromeda Project

We're on a collision course with the Andromeda Galaxy.

Help researchers understand the awesomeness of the Andromeda Galaxy, because one day we'll be in it.

Using survey data from the Hubble Space Telescope we're hunting for star clusters in Andromeda and hidden galaxies that lie behind.

Galaxy Zoo: Mergers How do galaxies merge? Select simulations that look similar to the targeted merger. Take your best matches, and improve them by tuning your simulations. Find the best of the best from your set of possible matches.

Galaxy Zoo: Supernovae Search for exploding stars! Help us catch exploding stars, known as supernovae. Data is provided by an automated survey at the world-famous Palomar Observatory in California, and astronomers are ready to follow up on your best candidates at telescopes around the world.
