Loading contentAstronomy is the rare science where an amateur in a backyard can still contribute to the research frontier — timing an occultation, catching a nova, or classifying a galaxy nobody has looked at before. This is the participation layer: the projects, the activities, the equipment, and the community that make the sky belong to everyone.
Where the public does real research — Zooniverse, Galaxy Zoo, Planet Hunters, Globe at Night, Aurorasaurus, and Stardust@home.
6 entriesThe ways amateurs watch the sky — backyard observing, variable-star, asteroid and comet observing, occultation timing, and meteor watching.
6 entriesThe tools of the hobby — from the first pair of binoculars and a Dobsonian to an astrophotography rig.
6 entriesHow astronomy reaches everyone — star parties, public observatories, dark-sky parks, and astronomy education.
4 entriesThe bodies that coordinate amateur astronomy — the AAVSO, the International Meteor Organization, and ALPO.
3 entriesA project that crowdsources real-time reports and photographs of the aurora from the public, improving where and when auroral displays are forecast — turning sky-watchers into a distributed sensor network for space weather.
The project that asked the public to sort galaxies by shape from survey images — and found volunteers could do it as well as experts, at enormous scale. Its classifications became a landmark dataset and the training labels for the machine-learning classifiers that followed.
A worldwide campaign to measure light pollution by having people compare the faintest stars they can see — often in Orion — against a set of star charts, and report what they see. The result is a global, year-on-year map of the brightening night sky.
A project inviting the public to search stellar light curves for the tiny dips of a transiting planet — finding candidates, including unusual ones, that automated pipelines had missed. A demonstration that human eyes still catch things algorithms overlook.
A project in which volunteers scanned microscope images of the aerogel flown on NASA's Stardust mission, hunting for the microscopic tracks of interstellar dust grains — a needle-in-a-haystack search that distributed human attention could solve.
The largest platform for people-powered research, where hundreds of thousands of volunteers help classify and analyse data across astronomy and many other sciences. It grew out of Galaxy Zoo and now hosts dozens of projects that turn human pattern-recognition into published results.
Each project, activity, piece of equipment, outreach effort, and organisation is a first-class knowledge-graph entity resolved through the Scientific Data Engine, reusing the aurora, the occultation and photometry methods, the meteor showers and constellations, the eruptive-variable-star class, the Stardust mission, the transit method, the galaxy-morphology-classification application, the Rubin Observatory, and the MAST archive already in the graph. Curated from NASA and the citizen-science and amateur-astronomy communities. Projects and organisations are named only where real. See source quality.
