Although astronomers have directly imaged a few dozen gas giants on the scale of Jupiter, Earth-sized planets are too small and dim to be directly imaged. That's not to say there's a shortage of Earth ...

Worlds that circle stars other than our own are called “exoplanets.” This specific one could be the very first planet like ...

Overlooked in the Kepler data and discovered by a citizen scientist, HD 137010 b is one of the most interesteing exoplanets ...

Learn about HD 137010 b, a cold Earth‑sized planet candidate that sits near the outer edge of its star’s habitable zone.

The first—and so far only—hint of the potential planet arrived in observations from NASA’s now retired Kepler space telescope ...

Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up ...

NASA has discovered a new super-Earth that has a year only lasting a few hours. The exoplanet K2-141b, was found very close to its orange sun-like star, and has an orbital period of less than one ...

A newly identified Earth-sized exoplanet with a year-long orbit may lie near its star’s habitable zone, but extreme cold could limit its chances of hosting liquid water.

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler ...
