A five-year study of data from the Kepler space observatory has found that over half the possible planets it has identified are either eclipsing binary stars or brown dwarfs.

The set includes KOI 7711 (short for Kepler 'object of interest'), which is just 30 percent larger than Earth and roughly the same distance from its star as the Earth is to the sun, meaning it ...

NASA’s Kepler space telescope adds 1,284 planets to the roster of worlds known to orbit other stars in our galaxy.

So far, the Kepler “Objects of Interest” are pretty interesting. Take KOI 191, which involves four planets in unstable orbits.

The possible planet is called KOI 172.02 (KOI stands for Kepler Object of Interest, a designation assigned to all planet candidates found by the telescope until they are confirmed as planets).

When the team looked at the data that Kepler has made public, they found something unusual with the planetary candidate KOI-872.01 (KOI stands for "Kepler Object of Interest").

This is in addition to a list of “Kepler Objects of Interest” that’s sort of the roll call of candidates-to-be-candidates. Using the new method, 428 candidates were validated as very likely ...

Classed as a “super-Earth,” candidate planet KOI (Kepler Object of Interest) 172.02 orbits within the habitable zone of a sun-like star. This means the planet, which has yet to be confirmed by ...

We present astrophysical false positive probability calculations for every Kepler Object of Interest (KOI)—the first large-scale demonstration of a fully automated transiting planet validation ...

Kepler is truly turning out to be an extraordinary planet hunter. The space-based telescope has now detected 4,696 objects of interest, including the new candidate planets.

Each of the signals below is shown in a pair of plots, one from an observation of Kepler Object of Interest (KOI) 817 and one from an observation of KOI-812.
