In this edition of our Who's who in the Zoo series meet Tom Donlon, a postdoctoral researcher at the University of Minnesota, who studies the Milky Way’s structure, evolution, and what it can tell us about dark matter.

Where exactly was a museum specimen collected? A new Zooniverse project invites volunteers to help turn location information from museum records into points on a map, making biodiversity data easier for researchers to use. The project also introduces new mapping tools that will eventually support many different kinds of research on Zooniverse. Yesterday, we launched a brand-new project: Notes from Nature - Putting Biodiversity on the Map…

Zooniverse is creating a new way for research teams to experiment with tools and approaches that aren’t currently possible within the standard Zooniverse Project Builder. These Custom Front Ends remain connected to Zooniverse infrastructure while giving researchers more flexibility to test new ways for volunteers to take part in research. Building projects on Zooniverse Since Galaxy Zoo launched in 2007, the founding of Zooniverse in 2009, and the launch of the Zooniverse DIY Project Builder platform (

We are excited to announce the launch of Overlap Zoo, a new project under the Galaxy Zoo umbrella! Among the several million galaxies classified in previous Galaxy Zoo projects, a small number of t…

In our “Love Letters to Zooniverse” series we share wonderful stories from volunteers who have made Zooniverse a meaningful part of their lives, often contributing to projects and communities over many years. Here is one more, from Svetoslav Alexandrov, a 39-year-old molecular biologist and astrobiology researcher from Bulgaria. Since becoming an active Zooniverse volunteer in 2022, Svetoslav has contributed to discoveries across several astronomy projects, become a project moderator and scientific co-author, and even had an asteroid named after him.

Projects on Zooniverse that engage with artificial intelligence and/or machine learning

This post was written by Hillary Burgess and Sam Blickhan. In June 2025, we announced an initiative to develop a set of recommendations for running AI/ML-engaged projects on the Zooniverse platform. After a year of collaboration and discussion with volunteers, experts in ethics, communications, AI, and participatory research, as well as Zooniverse project leads (noting that these groups are not mutually exclusive!), we are excited to finally share the results of this work.

NASA’s Nancy Grace Roman Space Telescope has successfully launched, beginning its journey toward a new era of wide-field space astronomy. Roman is NASA’s next flagship observatory, designed to survey vast areas of the universe in near-infrared light. Its observations will help scientists tackle some of the biggest questions in astrophysics: What is dark energy? How is dark matter distributed across the universe?

This year’s Zooniverse Team Meeting coincided with the incredible milestone of 1 billion classifications on the Zooniverse platform. In this vlog, the team behind the world’s largest an…

Linda Sass Constandi joined Galaxy Zoo in 2007, shortly after reading about the project in a newspaper. Nearly two decades later, Linda is still classifying, learning and cheering on new discoveries on Zooniverse.

The Zooniverse, a NASA grantee that runs the world’s largest platform for online people-powered research, has reached an extraordinary milestone: 1 billion

As we celebrate 1 billion classifications on Zooniverse, we continue the "love letters" series - messages to our team from Zooniverse volunteers. The letters come from different continents, age groups and lifestyles, but they all invite us to stay curious as we do science together. Today's letter is from Daria, who participated in 67 projects, contributed almost 60,000 classifications and discovered 6 galaxies at age 16.

The Zooniverse citizen science platform just hit a billion classifications from their volunteers: This milestone belongs to everyone who has contributed...

We are SO happy to announce that Zooniverse has reached an extraordinary milestone: 1 BILLION classifications contributed by volunteers!To give you a sense of what an extraordinary milestone this i…

We are saddened to share the passing of Candice Hansen-Koharcheck, a pioneering planetary scientist and an inspiration for and one of the leads of the Planet Four projects on Zooniverse. She was also a contributing researcher to the Jovian Vortex Hunter project on Zooniverse. Candy’s warmth, generosity, and passion for solar system exploration inspired countless collaborators and volunteers across our community, and her impact on planetary science will be felt for generations. You can read more about Candy’s remarkable life and legacy in this remembrance from the Planetary Science Institute -

Congratulations, Zooniverse! Today we have reached an extraordinary milestone: 3 million volunteers contributing to people-powered research around the world. From classifying galaxies and discovering exoplanets to tracking wildlife, transcribing historical records, and supporting research in ecology, climate science, cell biology, and the humanities, our community has helped make real science possible at a scale no individual team could achieve alone.

The latest list of Zooniverse projects in languages other than English is in. As always, thank you to Zooniverse volunteer Sallyann Chesson for preparing this updated list of translated projects, and to all our volunteer project translators for their ongoing contributions. Please note that we will no longer be posting these lists, as the Zooniverse's updated Project Page now allows you to filter projects by language.

We recently joined Astronomers Without Borders for a live conversation during Global Astronomy Month with Andrew Fazekas and Laura Trouille, Zooniverse Principal Investigator and VP of Science Enga…
