Jupiter has just been put on a cosmic diet. New measurements led by an Israeli team show that the giant planet’s diameter is about 8 kilometers smaller than long‑standing estimates and that its poles ...

(PhysOrg.com) -- A hot Jupiter - a type of celestial object unknown only fifteen years ago - is a Jupiter-sized exoplanet orbiting so close to its host star that its atmospheric temperature is thought ...

Combined chemical and hydrodynamic modeling offers a powerful tool beyond Jupiter. Scientists can apply similar techniques to Uranus, Neptune, and gas rich exoplanets. Such planets remain difficult to ...

Jupiter and Saturn host strikingly different polar storms, despite being similar giant planets, and scientists have long wondered why. New simulations suggest the answer may lie deep below the clouds.

Scientists studying Jupiter and Saturn’s polar storms suggest their dramatic differences arise from deep interior properties. Simulations show that “harder” or “softer” gas layers beneath the storms ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new, warm Jupiter-sized exoplanet orbiting a dwarf star. The newfound alien world, ...
