AI Insight
Zooniverse, the world's largest platform for online citizen science and a NASA grantee, has reached 1 billion volunteer classifications from participants worldwide. Since 2020, 31 NASA-sponsored projects on the platform have generated 120 million classifications from 324,000 volunteers, contributing to research on exoplanets, asteroids, brown dwarfs, solar wind effects, and wildlife management. These collaborative efforts have resulted in 96 scientific publications, with 56 papers including citizen scientists as co-authors.
Why it matters
This milestone demonstrates how public participation can significantly accelerate scientific discovery by combining human pattern recognition abilities with data from NASA missions and observatories. The model will become increasingly important for analyzing massive datasets from upcoming missions like the Nancy Grace Roman Space Telescope, showing that citizen science can make meaningful contributions to professional research while engaging millions in authentic scientific work.
Understand the Science
The Zooniverse, a NASA grantee that runs the world’s largest platform for online people-powered research, has reached an extraordinary milestone: 1 billion classifications contributed by volunteers around the world. This milestone is a celebration of everyone who has marked a dip in a light curve, confirmed the presence of a moving object in a short video, or identified species in a camera trap image. Each of these small contributions collectively advances our understanding of the universe.
A total of 31 NASA-sponsored citizen science projects have been hosted on Zooniverse, accounting for 120 million classifications by 324 thousand volunteers since 2020. Through projects like Planet Hunters TESS, Daily Minor Planet, Backyard Worlds: Planet 9, Space Umbrella, and Snapshot Wisconsin, volunteers help discover exoplanets, identify near-Earth objects and asteroids, search for brown dwarfs and planetary systems, analyze effects of the solar wind, and inform wildlife management decisions. These projects have led to 96 scientific publications, and 56 of these articles feature NASA citizen scientists as co-authors to recognize the significance of their research contributions. These efforts demonstrate how public participation can accelerate discovery by combining human curiosity and pattern recognition with data from NASA missions and observatories. Collaboration between volunteers, scientists, and computing technology will be even more important in the future as we tackle enormous and complex datasets, like those from NASA’s upcoming Nancy Grace Roman Space Telescope.
“One billion classifications represent far more than a number; it’s one billion moments of curiosity transformed into meaningful contributions to research,” said Laura Trouille, principal investigator of Zooniverse and vice president of Science Engagement at the Adler Planetarium. “Every classification on Zooniverse brings us one step closer to new discoveries and a deeper understanding of our universe, our world, and ourselves.”
Zooniverse is the world’s largest platform for people-powered research. Co-founded by the Adler Planetarium and the University of Oxford, with the University of Minnesota serving as a key institutional partner, Zooniverse enables anyone, anywhere to contribute directly to real scientific research. Through its six-year collaboration with NASA, Zooniverse provides science-enabling infrastructure to NASA researchers through tools and a community of more than 3 million registered volunteers.
