A distant exoplanet known as Kepler-51d is challenging astronomers once again. New observations from the James Webb Space ...

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 ...

Using data from NASA’s Kepler space telescope, a team of researchers, led by astronomers at San Diego State University, detected the new Neptune-to-Saturn-size planet orbiting between two previously ...

Relative sizes of the newly discovered habitable-zone planets and Earth. Left to right: Kepler-69c, Kepler-62e, Kepler-62f and Earth (except for Earth, these are artists' renditions). Image credit: ...

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 ...

The unusual system of three “super puff” planets has at least one more planet, revealed by its gravitational tug on other planets An unusual planetary system with three known ultra-low density ...

This artist’s concept illustrates the two Saturn-sized planets discovered by NASA’s Kepler mission. The star system is oriented edge-on, as seen by Kepler, such that both planets cross in front, or ...

This image from the paper is a visual representation of the planets in their abbreviated catalogue, showing planets by size and stellar temperature. Credit: arXiv (2023). DOI: ...

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 ...
