The Origin of an Atmosphere

There are four ideas for where the atmosphere comes from.

Those four ideas are 1. that the planet-elements which made the planets made the atmosphere too, 2. that the atmosphere was drawn to the planet from the cloud out of which everything came, 3. that comets hit the planet and brought molecules of air with them, 4. that volcanos erupted and made an atmosphere.

The one that applies to Jupiter is hypothesis #2, in which the original molecules, which Jupiter drew out of the primitive gas cloud stayed, and form the atmosphere today.

How a planet-to-be sweeps up nearby material to be part of itself

As shown in this picture, while they were forming in the solar nebula, the core of the planets-to-be drew material to themselves from the cloud of gas and dust around them. The bigger planets-to-be were...more

A Look at the History of Jupiter's Atmosphere

The giant planets have definitely changed since their formation. But how much remains to be seen. Most of the original air of the giant planets remains in place. (The earth-like planets lost most of their...more

Jupiter's Mesosphere

The mesosphere of Jupiter is a region of balance between warming and cooling. That essentially means that nothing happens there. Except for diffusion, the atmosphere is still. Upper reaches of the atmosphere,...more

An Overview of Jupiter's Atmospheric Structure

As on Earth, the atmosphere of Jupiter consists of a troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the region where the visible clouds are to be found. The stratosphere, as...more

Jupiter's Stratosphere

The stratosphere of Jupiter is a region of warming as determined by infrared measurements of methane (CH4) in the region. Like the troposphere, the stratosphere is warmed by the sun, warmed by Jupiter's...more

Jupiter's Troposphere

The troposphere of Jupiter is where the clouds are. Clouds form in regions of strong atmospheric motion, when condensation takes place. The troposphere is the region rapidly stirred by vertical motions....more

Altitude Variations of the Belts & Zones

On Jupiter, the winds in the belts and zones blow first in one direction, then in the opposite direction. Wind blows east in a belt, and west in a zone. The clouds rise up in a belt, and drop down in a...more
