Kepler was one of the most successful exoplanet-hunting missions so far. It discovered 2,600 confirmed exoplanets – almost half of the total – in its almost ten years of operation. However, most data analysis focused only on one of the 150,000 targets it “intended” to look at. While it was making those observations, there were a myriad of background stars that also had their light captured incidentally. John Bienias and Robert Szabó of Hungary’s Konkoly Observatory have spent a lot of time looking at those background stars and recently published a paper suggesting there might be seven more exoplanet candidates hiding in the data.

Do exoplanets have exomoons? It would be extraordinary if they didn’t, but as with all things, we don’t know until we know. Astronomers thought they may have found exomoons several years ago around two exoplanets: Kepler-1625b and Kepler-1708b. Did they?

NASA’s Kepler spacecraft ended its observations in October 2018 after nine and a half years, a solid six years beyond its planned duration. It discovered 2,711 confirmed exoplanets and another 2,056 exoplanet candidates as of August 2022.
Now, astronomers at MIT and the University of Wisconsin uncovered three more exoplanets in the data from Kepler’s final days of observations. They needed the help of dedicated amateurs to do it.
