SETI Institute + Unistellar Citizen Science

Feel the thrills of scientific discovery

Citizen Science is collaborative research between amateur and professional scientists who share a common goal. Most citizen scientists are everyday people, who are curious about science and want to collaborate with others.

 

UNISTELLAR focuses on citizen space science, which explores the realm beyond planet Earth. Professional space scientists often need the support of citizen scientists – there are simply not enough devices and time to collect all the information that exists about our universe, so citizen scientists use their passion to help gather and analyze data. This work allows us to expand our knowledge of the universe.

Featured Monthly Science Target:

Comet 2025 (K1/ATLAS)

 

Comet K1 is breaking apart! Comet K1 skimmed just 0.3 AU from the Sun during its perihelion on October 8, and then in early November underwent a dramatic outburst. Then on November 10, observations from Teide Observatory revealed two large fragments — clear evidence the comet had split. Just three days later, a third fragment appeared, indicating that the comet is in pieces. Even more exciting, our citizen science community captured the evolving breakup in real time! Citizen astronomers observed all three fragments, tracking this transformation from around the world. Below you can see Comet K1 before, during, and after the fragmentation, but that’s not all – we still need observations to study what’s left of this comet! After fragmenting, the comet had another close solar approach on Nov 26, but it remains bright as it heads out of our telescopic reach. More data will tell astronomers how the comet fragment continues to evolve after the breakup and solar flyby, so observe while you still can!

To observe Comet K1:

Use your smartphone to generate a Deep Link with our comet ephemeris tool. Make at least one recording.For detailed instructions, see the Tutorial → During Observation → B. The Comet is NOT in the App Catalog.

UNISTELLAR Community Map

Join the Network

The UNISTELLAR Network is a worldwide community of Citizen Astronomers working in partnership with professional astronomers at the SETI Institute. Members use their UNISTELLAR telescope to collect astronomical data, which is supplied to SETI Institute astronomers who then use it to develop predictions and models. UNISTELLAR community members connect through social media or slack to share results and plan observation nights with one another.

Our Citizen Astronomers observe space objects such as asteroids, comets, exoplanets and more. No matter your generation, geography, education or interests, there is a meaningful citizen science program for you.

We already accomplished scientific missions

The worldwide dimension of the UNISTELLAR network and its collaboration with the NASA and SETI Institute has made it possible for citizen astronomers to provide crucial information and accomplish memorable missions.

Fragmentation of comet ATLAS

A group of 40 citizen astronomers from around the world simultaneously observed the Comet ATLAS to build a highly detailed super image. The crowd-generated images highlight the disintegration of the comet.

Shaping the 69th Near-Earth Asteroid in history

For two months, 26 citizen astronomers observed an asteroid flying by our planet. With their observations, scientists successfully shaped the asteroid 1999 AP10. “It fascinates me how our observations can result in something so detailed,” affirmed citizen astronomer Justus, from Georgia.

DART: A Mission to Protect our Planet

Unistellar citizen astronomers observed asteroid Dimorphos before, during, and after the impact of the DART spacecraft. Their observations provided important scientific data on the asteroid’s characteristics, which are now published in the prestigious academic journal Nature.
