An international team of astronomers has announced the discovery of twelve planets orbiting nine low-mass stars. The discovery is based on data from the...
Astronomers using data from the NASA Kepler spacecraft’s reborn K2 mission have found a triple system of super-Earth exoplanets around a cool star called...
An international team of citizen scientists and professional astronomers has discovered a system of at least five massive exoplanets, orbiting the Sun-like...
A study of 909 exoplanets in 355 multi-planet systems discovered by NASA’s Kepler Space Telescope reveals that, unlike our Solar System, other planetary...
A research team led by University of Hawaii astronomers has found two remarkably similar gas giants orbiting very close to their parent red-giant stars.
The...
A team of researchers reports the discovery of an eighth planet orbiting Kepler-90, a Sun-like star approximately 2,545 light-years from Earth in the constellation...
A team of professional and amateur astronomers using data from NASA’s Kepler mission has spotted the dusty tails of six exocomets orbiting KIC 3542116,...

EPIC 228732031b orbits so close to its parent...
Astronomers using data from the NASA Kepler spacecraft’s reborn K2 mission have discovered a planetary system containing at least three exoplanets, orbiting...
Using a novel photometric technique to enhance observations from NASA’s Kepler Space Telescope, astronomers have performed the most detailed study yet...
Astronomers have classified extrasolar planets in the same way that biologists identify new species and have learned that the majority of planets found...
Astronomers have used data gathered by K2, the second mission of NASA’s Kepler Space Telescope, to confirm details of TRAPPIST-1h, the outermost of seven...
Using the NASA/ESA Hubble Space Telescope, NASA’s Kepler and Herschel space observatories, astronomers have discovered a new moon in our Solar System,...
Using NASA’s Kepler spacecraft on its K2 mission, astronomers have discovered five new planets around other stars, including two extraordinary companions...
Signs of powerful changing winds have been detected on an extrasolar gaseous planet called HAT-P-7b, which is 40% larger than Jupiter and orbits a star...
Kepler 11145123, a slowly rotating star roughly 5,000 light-years away, is the most spherical natural object ever measured, more spherical than the Sun,...
Astronomers using observations from NASA’s Kepler and Swift space observatories have spotted 18 fast-spinning stars that produce X-rays at more than...
Planets form from epic collisions between asteroids and even bigger bodies, called protoplanets. Sometimes the colliding bodies are ground to dust, and...
