The planet Jupiter is putting on quite a show in our night sky this month, and you don't need any special equipment to enjoy it.

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 ...

Spectacular clouds swirl across the surface of Jupiter. These clouds contain water, just like Earth's, but are much denser on the gas giant—so thick that no spacecraft has been able to measure exactly ...

Jupiter harbors more oxygen than the sun, a new study finds, giving astronomers a crucial clue about how our solar system's planets formed.

Unlike earlier studies, which often examined chemistry and atmospheric motion separately, the new simulations combined both.

Jupiter, the giant planet, appeared to align closely with the full Wolf moon, creating a stunning celestial display visible ...

There’s no mistaking Jupiter in the sky these Pottsville winter evenings, rising in the southeast as evening twilight ends.

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real ...
