We’re thrilled to share that Galaxy Zoo volunteers are about to reach an incredible milestone: 1,000,000 classifications on GZ JWST!

GZ JWST first launched back in April 2025 with over 300,000 galaxies from the COSMOS-Web survey. In the 200 days since, you have worked through this remarkable dataset at an extraordinary pace, helping us trace how galaxy structures change over cosmic time. Thanks to your classifications, we’re gaining a clearer picture of what galaxies looked like in the early Universe and how their shapes evolved into the systems we see around us today.

Galaxy Zoo has always been powered by the curiosity and dedication of its volunteers. Thank you for donating your time, your attention, and your enthusiasm.

Highlights from Talk

As we celebrate this milestone together, it’s worth taking a moment to look at some of the excitement happening on Talk. These are the top five most-discussed galaxies from this survey, with the images below counting down from #5. Each image links to its Notes page, so check it out and join in.

You can find many more stunning galaxies on Talk. For example, the JWST Gems tag highlights some of the most striking objects volunteers have come across. As always, thank you for making Talk such a joy to explore — it’s a pleasure to see what you all discover. And thank you for helping us (almost) reach one million classifications on GZ JWST! We can’t wait to see what you’ll uncover in the next million. 🎉
