Want to help identify the ages of star clusters in the Southern Pinwheel Galaxy, M83?

It is difficult to get a computer to measure star cluster age categories or the structure of glowing hydrogen gas since these features come in all shapes and sizes. Similarly, it can be hard for a computer to measure the properties of a star cluster in a very crowded field like this.

Human beings are much better than computers at making the kinds of distinctions astronomers need to gauge the ages of the clusters, so now you can have a seat and join the fun - you get to be the unpaid labor. The interactive online project Star Date: M83 will provide you with a variety of star clusters and a series of questions that help define their ages.

Scientists will use your info to learn how star clusters are born, evolve and eventually disperse into a galaxy.
