Jupiter is already the biggest planet by far in our solar system, but new research suggests it was somehow once even larger than it is now. Twice as large, in fact. To put that into context, those ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

Jupiter, the largest planet in the solar system, was 2 to 2.5 times bigger in its earlier life, according to new research. Credit: NASA / JPL-Caltech / SwRI / MSSS / Tanya Oleksuik Jupiter, the ...

Jupiter-like planets may be a common occurrence in the interplanetary space near our solar system, especially around stars similar to our sun, a new study suggests. If future observations confirm this ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

If you've ever wondered why we are here, then you can thank Jupiter for part of the answer. A new study from Rice University suggests that if it weren't for the gas giant, the Earth would have ...

The giant planets weren't always where we find them today. Jupiter, Saturn, Uranus and Neptune formed in a more compact configuration and later underwent a violent reshuffling that scattered them to ...

In a first, scientists have discovered a massive wave of solar wind that hit Jupiter and compressed its protective bubble. A solar wind event in 2017 struck Jupiter’s magnetosphere, generating an ...

NASA's Juno spacecraft captured this view of Jupiter during the mission's 54th close flyby of the giant planet Sept. 7, 2023. People around the world will have a chance this weekend to catch what ...

Xi Zhang, a professor of Earth and planetary science at UC Santa Cruz, has discovered that an exoplanet classed as a ...

Jupiter’s skies can glow with lights more intense than anything on Earth. Its polar auroras shine when charged particles crash into its upper atmosphere, creating bursts of heat and energy. These ...
