NASA's prolific Kepler space observatory, which has found signs of thousands of alien planets, will keep hunting strange new worlds for at least four more years, the space agency announced Wednesday ...

A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than ...

An unusual planetary system with three known ultra-low density 'super-puff' planets has at least one more planet, according to new observations. An unusual planetary system with three known ultra-low ...

If you’re looking for Earthlike planets around other stars — places about the size and temperature of our own planet, where life could in theory be found — it might seem like a letdown to stumble ...

NASA’s Kepler mission has verified 1,284 new planets – the single largest finding of planets to date. “This announcement more than doubles the number of confirmed planets from Kepler,” said Ellen ...

NASA's Kepler mission ended in 2018 after more than nine years of fruitful planet-hunting. The space telescope discovered thousands of planets, many of which bear its name. But it also generated an ...

With the help of citizen scientists, astronomers discovered what may be the last three planets that the Kepler Space Telescope saw before it was retired. More than 5,000 planets are confirmed to exist ...

PASADENA, Calif. — NASA’s Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the “habitable zone,” the range of distance from a star where the ...

The first planet ever spotted by the Kepler space telescope is falling into its star. Kepler launched in 2009 on a mission to find exoplanets by watching them cross in front of their stars. The first ...

The most prolific planet-hunting machine in history has signed off. NASA's Kepler space telescope, which has discovered 70 percent of the 3,800 confirmed alien worlds to date, has run out of fuel, ...

A team of astrophysicists led by Lauren Weiss, assistant professor in the Department of Physics and Astronomy at the University of Notre Dame, created the first-ever catalog of small, Earth-like ...
