But unlike Jupiter, Venus does have phases, going from not illuminated at all (when it is between the Earth and the Sun) to ...

“This research helps us understand how planets form and evolve… by studying what’s happening inside Jupiter, we get closer to ...

The Juno observations showed that Jupiter has an equatorial diameter of 88,841 miles (142,976 km), which is about 5 miles (8 ...

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 ...

“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 ...

New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

Combined chemical and hydrodynamic modeling offers a powerful tool beyond Jupiter. Scientists can apply similar techniques to ...

New data from NASA's Juno orbiter reveals Jupiter is slightly smaller and more 'squashed' than scientists previously thought.

Updated measurements from NASA’s Juno spacecraft could help researchers better understand the planet's mysterious interior, ...

Not all of the solar system’s building blocks formed simultaneously. Some of the first solid bodies, or planetesimals, formed in the first million years after the Sun was born. Others, including the ...

An international team of researchers using data from NASA’s Juno mission has redefined the physical dimensions of the gas ...
