The ALMA images revealed that Io’s atmosphere becomes incredibly unstable when it passes through Jupiter’s massive shadow. This occurs every 42 hours during Io’s orbit around Jupiter.

That means the atmosphere of Jupiter also has a higher ratio of heavier elements than the material from which the planet formed some 4.5 billion years ago.

Storm warning on Jupiter A huge storm on Jupiter broke out in December of 2016, just south of the planet's equator and about 60 degrees east of the famous Great Red Spot. Amateur astronomer Phil ...

The outermost layer of Jupiter's atmosphere is the exosphere, where gas particles can escape into space. With no clear boundary, the exosphere bleeds into interstellar space.

In fact, Jupiter's atmosphere has dramatic weather and structures which scientists are still learning about — including a prevalence of strange objects called mushballs.

The Juno spacecraft orbiting Jupiter just revealed mechanisms driving mammoth storms in the Jovian atmosphere. Storms on Jupiter form ammonia-rich hail — called mushballs — in the atmosphere ...

Previous reports of water on Jupiter have been conflicting. When the Comet Shoemaker-Levy smashed into Jupiter's surface, it kicked up oxygen that indicated water in the atmosphere might be plentiful.

Using data from the Juno orbiter, there is at least 0.25 percent water in the planet's atmosphere, notably near the equator, NASA JPL wrote in a blog post. "Just when we think we have things ...

Being so close, its atmosphere its heated to a scorching 2,000- degrees Celsius, which makes it puff up to a large size that's six times the volume of Jupiter.

Jupiter’s upper atmosphere is hundreds of degrees warmer than expected. After a decades-long search, scientists may have pinned down a likely source of that anomalous heat. The culprit, a new ...
