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 ...

NASA shared that with a more precise shape, it will help astronomers understand data from planets seen passing in front of ...

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

Jupiter shrunk not; the yardstick improved. The largest planet of the solar system has been used decades as a sort of calibration beacon: a “known” giant, whose existence largely goes unnoticed, whose ...

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 ...

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

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

Jupiter will make its closest approach to Earth in 59 years on Monday, according to NASA. The largest planet in our solar system, the gas giant will be at opposition, meaning Earth is directly between ...

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

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

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 ...

NASA has recorded the most powerful volcanic eruption outside of Earth on Io, one of Jupiter’s moons. On December 27, 2022, Juno, NASA’s spacecraft, witnessed numerous active volcanoes erupting ...
