A massive solar windstorm in 2017 compressed Jupiter's magnetosphere "like a giant squash ball," a new study reports.

Big storms can strip some parts of Jupiter's atmosphere of ammonia, while leaving buried reservoirs of the gas elsewhere.

In May 2020, astronomers for the first time observed a planet getting swallowed by its host star. Based on the data at the ...

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 ...

Although the impact of Comet Shoemaker-Levy 9 seems like a once-in-a-lifetime event, impacts still occur at Jupiter. You ...

"The solar wind squished Jupiter's magnetic shield like a giant squash ball. This created a super-hot region that spans half the planet. Jupiter's diameter is 11 times larger than Earth's, meaning ...

Out past Neptune are countless small icy and rocky bodies called Trans-Neptunian Objects (TNOs), and many of these have moons as well. While some TNOs could be called dwarf planets because of their ...
