Jupiter's signature stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium. The dark orange stripes are called belts, while the lighter bands are called zones, and they flow east and west in opposite directions.

The atmosphere of Jupiter essentially makes up the entire planet. The gas giant has no firm surface to touch down on. Instead, it is composed almost entirely of hydrogen and helium, with a...

Jupiter is the largest planet in our solar system. If Jupiter was a hollow shell, 1,000 Earths could fit inside. Jupiter also is the oldest planet, forming from the dust and gases left over from the Sun's formation 4.5 billion years ago.

NASA’s James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter’s atmosphere. The high-speed jet stream, which spans more than 3,000 miles (4,800 kilometers) wide, sits over Jupiter’s equator above the main cloud decks.

NASA’s Juno mission captured these elaborate atmospheric jets in Jupiter’s northern mid-latitude region. This detailed, color-enhanced image reveals a complex topography in Jupiter’s cloud tops.

The upper atmosphere of Jupiter is the interface between the planet’s magnetic field and the underlying atmosphere. Here, the bright and vibrant displays of northern and southern lights can be seen, which are fuelled by the volcanic material ejected from Jupiter’s moon Io.

jupiter’s atmosphere is mostly hydrogen and helium, which are the lightest and most abundant gases in the universe. The weather on Earth is mainly driven by heat from the sun. But the sunlight on Jupiter is 25 times weaker than that on Earth, yet its winds are three to four times stronger.

New findings from NASA’s Juno probe orbiting Jupiter provide a fuller picture of how the planet’s distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds.

NASA’s Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms in the solar system, taking place more than 500 million miles away on the giant planet Jupiter.
