Let’s learn about citizen science

Volunteers all over the world collect important data on the environment, health, space and more

Citizen scientists all over the world contribute to research by collecting and analyzing data.

Science may seem like a spectator sport. That is, it might feel like trained scientists do all the work while everyone else watches. But anyone can participate in science. Volunteers gather and analyze data for scientific studies all the time. These citizen scientists have advanced the research on climate, health, space and more. And you could be one of them!

Some citizen scientists collect data on the world around them — often using only their phones. The Globe at Night project, for instance, crowd-sources data on light pollution. NoiseTube is a similar effort to map noise pollution. Hikers, birders and other nature lovers share wildlife photos on iNaturalist. Those data contribute to the study of our planet’s biodiversity.

But not all citizen science takes place outdoors. There’s plenty that doesn’t require leaving your home. On Instant Wild, volunteers tag animals in photos taken by cameras out in the wild. Those labels help conservation efforts. And online gamers playing Foldit and Neureka contribute to health research.

Citizen science isn’t just a great way to learn about a new field and get inspired. Non-pros bring fresh ideas and perspectives to the scientific community. And some even make big discoveries. Citizen scientists were the first to spot mysterious “yellowballs” in telescope images, for instance. And they were also the first to identify a weird purple air glow called STEVE.

No matter what kind of science catches your fancy, there’s probably a citizen-science project for you. So, get out there and get your science on. Who knows? Your casual afternoon pastime may help lead to the next great discovery.
