A new ‘mini’ project went live yesterday called Galaxy Zoo Quench. This project involves new images of 6,004 galaxies drawn from the original Galaxy Zoo. As usual, everyone is invited to come and classify these galaxies, but this project has a twist that makes it special! We hope to take citizen science to the next level by providing the opportunity to take part in the entire scientific process – everything from classifying galaxies to analyzing results to collaborating with astronomers to writing a scientific article!

Galaxy Zoo Quench is examining a sample of galaxies that have recently and abruptly quenched their star formation. These galaxies are aptly named Post-Quenched Galaxies. They provide an ideal laboratory for studying galaxy evolution. So that’s exactly what we want to do: with the help of the Zooniverse community. We hope you’ll join us as we try out a new kind of citizen science project. Visit http://quench.galaxyzoo.org to learn more.

The entire process of classifying, analyzing, discussing, and writing the article will take place over an ~8-12 week period. After classifying the galaxies, Quench volunteers can use tools.zooniverse.org to plot the data and look for trends. We also have a special Quench Talk forum to discuss and identify key results to include in the paper – above you can see examples of some of the cool objects people have already found and discussed.

Have questions about the project? Leave a comment here or ask us on Twitter (@galaxyzoo) or on the Galaxy Zoo Facebook page. In case you’re worried: the regular Galaxy Zoo will continue as normal.

Now go visit http://quench.galaxyzoo.org and start classifying!
