Real discoveries, made by volunteers.
Citizen scientists have found planets, solved protein structures, pinned down record primes and built open AI datasets. This guide explains how research works and where you can start contributing today.
Four fields to explore
Astronomy
Classify galaxies, hunt exoplanets and comets, and measure the night sky from your backyard.
Planets · comets · pulsars →Biology
Log wildlife, fold proteins in a game and trace neurons through the brain.
Species · proteins · neurons →Mathematics
Search for record primes, settle Busy Beavers and help computers check proofs.
Primes · tilings · proofs →AI
Donate your voice, label data and join open communities that build models in public.
Data · models · languages →From curious to contributor
Pick a question you care about
Birds outside your window, a star you can see, a prime you can test. Interest keeps you going.
Join an established project
Platforms like Zooniverse, iNaturalist and SciStarter handle training, data quality and credit.
Learn the protocol
Follow the project's instructions exactly. Consistent methods are what make volunteer data usable.
Talk to the community
Forums and talk pages are where odd findings get noticed. Many discoveries started as a forum post.
