Astronomers have made a remarkable discovery in the Kepler-139 star system, uncovering an alien planet that had previously evaded detection. The newly identified exoplanet, Kepler-139f, is a giant ...

This makes it 35 times the mass of Earth and a year on its planet lasts 355 days, the discoverers noted in their findings published in The Astrophysical Journal Letters. The planet was detected after ...

Kepler has been searching for signs of supernovae among 50 trillion stars in 500 distant galaxies every 30 minutes for the past three years, according to the Ames Research Center.

The Kepler Space Telescope has spotted more than 2,700 potential exoplanets since its launch in 2009, ... The new findings will be published in an upcoming issue of the Astrophysical Journal.

American space agency NASA announced the discovery of a planetary system that isn't flat, has transit timing variations, and ...

Kepler-11 is a sun-like star around which six orbiting planets have so far been discovered. At times, two or more planets pass in front of the star at once, as shown in this artist’s conception ...

Kepler-1658b, orbiting with a period of just 3.8 days, was the first exoplanet candidate discovered by the Kepler space telescope in 2009. In 2019, astrophysicist Ashley Chontos used sound waves ...

And, because NASA’s now-retired Kepler space telescope discovered it, it proves that even older data has more information to reveal if we look back at it. An illustration showing the orbits of ...

But Kepler kept observing for an additional two years before the second of its four reaction wheels, which are needed to accurately point the telescope, failed in May 2013 (SN: 6/15/13, p. 10).

NASA's Charlie Sobeck, former manager of the Kepler Space Telescope mission, discusses the monumental findings of the spacecraft and NASA's decision to retire it in orbit.

The Kepler telescope, which was designed to search for planets like those found in the Kepler-385 system, stopped its primary observations in 2013, and conducted an extended mission until 2018.

NASA's Kepler space telescope may be hobbled, but scientists continue to pull new discoveries from its huge dataset. The space agency will announce more findings by Kepler — whose original ...
