Jupiter, long treated as the solar system’s fixed point of planetary normalcy, has just been knocked off that pedestal. New measurements from NASA’s Juno spacecraft show the gas giant is slightly ...

For over 50 years, we thought we knew the size and shape of Jupiter, the solar system's largest planet. Now, Weizmann ...

Thick, swirling clouds cover Jupiter from pole to pole. They hold water like Earth’s clouds, but at far greater density.

The planet's radius from pole to center has been revised to 66,842 km, and at the equator to 71,488 km. That makes it about 12 km smaller along the poles, and about 4 km smaller at the equator, than ...

Jupiter’s swirling storms have concealed its true makeup for centuries, but a new model is finally peeling back the clouds.

“Textbooks will need to be updated,” study co-author Yohai Kaspi, a planetary scientist at the Weizmann Institute of Science in Israel, said in a statement. “The size of Jupiter hasn’t changed, of ...

International scientists led by the Weizmann Institute of Science have conducted an analysis based on measurements from ...

New research data using NASA’s Juno spacecraft shows Jupiter is slightly smaller and flatter than decades-old estimates.

By Will Dunham WASHINGTON, Feb 4 (Reuters) - Jupiter, without a doubt, is the biggest planet in our solar system. But it ...

The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the ...
