Marseille and San Francisco, June 27. Unistellar is proud to announce that the eVscope, its revolutionary and powerful new consumer telescope, has demonstrated the ability to detect transiting exoplanets. This will allow citizen astronomers who soon receive the first eVscopes to begin contributing—easily but decisively—to one of the most exciting scientific endeavors in astronomy today: the search for worlds around distant suns.
Unistellar is the start-up behind this uniquely user-friendly digital telescope. The eVscope’s light-amplification technology and autonomous field detection make it possible for anyone to observe galaxies, nebulae, and comets in unparalleled crisp and colorful detail. In partnership with the SETI Institute, the Unistellar eVscope also allows everyone to contribute to astronomical discoveries while observing the night sky.
The Unistellar team recently used an eVscope to identify the transit of two Jupiter-size planets in distant constellations: Osiris, known as HD 209458b, a gas giant 160 light-years from our Solar System; and WASP-43b, a “hot Jupiter” 280 light-years away. The Unistellar eVscope detected the small variation in light generated when these exoplanets traveled in front of their stars.

“Detecting transiting exoplanets with a worldwide array of these powerful backyard telescopes will generate invaluable astronomical data,” explained Franck Marchis, senior astronomer at the SETI Institute and Unistellar’s Chief Scientific Officer. “With enough data points collected from coordinated observing campaigns using eVscopes, scientists will be able to refine the orbits of those new worlds, probe their surroundings, and detect tiny gravitational influences that indicate of the presence of a smaller nearby exoplanet in the same system.”
A single Unistellar eVscope was sufficient to make this detection. Soon, the company will start delivering more than 2,500 pre-ordered digital telescopes. This will create the world’s largest network of citizen astronomers, each of whom will be able to engage in an unprecedented level of collaboration with professional, amateur, and even novice astronomers conducting worldwide observation campaigns—including large institutional exoplanetary projects such as TESS, PLATO and JWST.
“The Unistellar eVscope has demonstrated that it is both a breathtaking deep-sky observing device and a groundbreaking scientific tool,” said Laurent Marfisi, Unistellar’s CEO. “By proving that exoplanet detection is possible with our citizen astronomy network, we are getting closer to our goal of creating a new and unprecedented level of space exploration.”
About Unistellar
Unistellar is the start-up behind the eVscope, a unique, compact, and user-friendly digital telescope. Its light-amplification technology allows users to observe galaxies, nebulae, and comets in unparalleled crisp and colorful detail. In partnership with the SETI Institute, the Unistellar eVscope also allows anyone to contribute to astronomical discoveries while observing.
The Unistellar eVscope received a CES Innovation Award in 2018 in the category Tech for a Better World and has been nominated for a SXSW 2019 Innovation Award. It has raised more than $3 million through crowdfunding, and more than 2,500 digital telescopes have already been pre-ordered.
Unistellar will be present at the Star’s Up Meudon, near Paris, on June 28 and 29, and at the World Conference of Science Journalists in Lausanne on July 2 and 3.
