Four Small Worlds Discovered Orbiting Nearby Star
Los Angeles CA (SPX) Apr 02, 2025 A quartet of diminutive planets has been confirmed in orbit around Barnard's Star, a nearby red dwarf long known for stirring debate over questionable planet sightings. Thanks to cutting-edge observational tools, scientists now say the new detection is solid. The discovery marks a milestone in tracking down small exoplanets across vast interstellar distances. Barnard's Star, just six light-years away, has been a challenging target due to its jittery nature and the difficulty of distinguishing genu ... read more |

Small and large planets have significantly different upbringings
Los Angeles CA (SPX) Mar 11, 2025 The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of exoplanets - from the size of Jupiter down to the size of Mars - and shown that small planets have nearly circular orbits, while giant planets have orbits about four times more elliptical than sm ... read more 
Astronomer finds gas giant exoplanets formed earlier than previously thoughtColumbus OH (SPX) Mar 11, 2025 A fresh look at past data reveals that exoplanets with masses similar to Jupiter formed much sooner than previously thought, according to new research.
