Citizen Science Finds New Role In Research From Exoplanets To Health

Citizen scientists are helping to reshape scientific research across disciplines, contributing to discoveries in astronomy, biology and biomedical science, according to researchers at Vilnius University Library.

A new analysis by Indra Giraitė and Dr Gitana Naudužienė argues that public participation in research is not just growing in scale but playing an increasingly central role in knowledge creation, policy input and scientific decision-making.

The paper highlights how contributions from non-professionals have helped identify new species, find pollution hotspots and even classify galaxies. But the authors say the future of citizen science depends on shifting the relationship between researchers and communities from data extraction to equal partnership.

Citizen Science Has Deep Roots

While the term “citizen science” was formally defined in 1995 by British sociologist Alan Irwin, the practice has a much longer history.

Irwin described citizen science as a model where the public helps shape scientific processes and outcomes, rather than simply observing from the sidelines. He also introduced the idea of “scientific citizenship” – the belief that society has a right to be involved in both producing knowledge and influencing decisions that affect their lives.

Giraitė and Naudužienė trace the origins of citizen participation in science back to the 18th and 19th centuries, when educated individuals often worked outside institutional settings. Michael Faraday, a former bookbinder’s apprentice, became a pioneer in physics and chemistry. Antonie van Leeuwenhoek, a cloth merchant, constructed his own microscopes and discovered bacteria. Charles Darwin, they note, developed his theory of evolution through correspondence with around 2,000 contributors from around the world.

Digital Tools Are Driving A Revival

The professionalisation of science in the 20th century limited public involvement, but some long-running projects survived. One example is the Christmas Bird Count, launched in 1900 by the US-based National Audubon Society, where volunteers help track bird populations every year. Australia has a similar Christmas Beetle count and programs like the Great Barrier Reef foundation’s Reef Recovery project.

Digital technology has opened the gates again. Smartphones, sensors and cloud platforms have allowed widespread participation in areas like climate science, biodiversity and astrophysics.

Projects such as eBird demonstrate the scale now possible. Some 700,000 users have submitted more than 1.1 billion bird observations to the platform, generating datasets few professional labs could match.

Concerns remain about the reliability of non-professional data. But the authors argue that structured verification, combined with the volume of contributions, gives these platforms real scientific value.

Beyond Data Collection

The authors say the most meaningful projects treat citizens not just as data gatherers but as collaborators in the scientific process.

They point to the Dragonfly Mercury Project, where 4,500 participants across 107 US national parks helped identify environmental risks through fieldwork and analysis. This helped uncover pollution patterns that traditional monitoring had missed.

“Citizen science is strongest when people are not confined to technical roles but recognised as genuine contributors,” the authors write.

The growing influence of Ai adds another layer. Since algorithms rely on datasets, ensuring that those datasets include diverse contributions from the public can help build more inclusive and equitable systems.

The authors describe this shift as a move from “science for people” to “science with people” – a framing that embeds participation into how research is designed and delivered.

Real-World Discoveries From Non-Scientists

Examples of citizen-led discovery now span multiple disciplines.

In the biodiversity space, iNaturalist allows users to upload photos of wildlife, feeding an open database used by researchers. A Lithuanian nature enthusiast used the app to document a previously unknown mushroom species in 2020.

In astronomy, Galaxy Zoo asks users to help classify galaxies using their visual pattern recognition skills. The platform helped uncover Hanny’s Voorwerp, a rare gas cloud spotted by a Dutch schoolteacher that offered new insights into galactic evolution.

NASA and NOAA’s GLOBE initiative involves students in more than 120 countries collecting environmental data that feeds into climate studies. In the biomedical sector, Fold.it gamifies protein-folding challenges to accelerate research.

These projects, the authors argue, not only build research capacity but help the public connect with science in direct and meaningful ways.

True Partnership Still Missing

Despite the success stories, Giraitė and Naudužienė say the full potential of citizen science will only be realised when structural changes are made.

“Citizen science has enormous potential,” they write, “because it can open scientific processes to society, democratise knowledge creation, transform public relationships with science and mobilise communities to address global challenges.”

But that will only happen if citizen contributions are acknowledged as part of the academic value chain.

They argue that funding models, research incentives and institutional cultures need to evolve. Public contributions must be recognised in research metrics, policy development and academic reward systems.

“Citizen science should not be seen as a data-collection service,” they conclude, “but as an equal partnership in the process of creating knowledge.”
