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

A new discovery suggests the possibility of an exomoon with an unprecedentedly large mass, thousands of times larger than any moon in our Solar System.

What would it take for Jupiter to ignite and become our second sun? What if Jupiter gained just a little bit more mass during its formation period, and then ignited to become a star? How different ...

Far from the Sun’s heat, orbiting the outer planets of the solar system, are moons with oceans of liquid water beneath their frozen surfaces. Keith Cooper finds out how planetary scientists are ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages 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 ...

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, may have been responsible for a mysterious age gap in the early solar system's planet building blocks. Credit: NASA / JPL-Caltech / SwRI / MSSS / Tanya ...
