Unlike Earth’s atmosphere, Jupiter’s “sky” hosts magnificent shades of orange, white, brown and blue.
Before I get too excited talking about the atmospheres of other planets, first we have to talk about what an atmosphere actually is.
Earth’s atmosphere is split into different layers. ESA
The atmosphere is normally the outermost layer of a planet. On rocky worlds like Earth it is usually the lightest and thinnest layer.
The thing that makes an atmosphere an atmosphere is what it’s made of. It’s not made up of big lumps of rocks or huge swirling oceans; it is made up of gases.
Atmospheres can contain a wide variety of gases. Most of Earth’s atmosphere is a gas called nitrogen that doesn’t really react with anything. There’s also a fair bit of oxygen, which is what we need to breathe. There are also two other important gases called argon and carbon dioxide and tiny amounts of lots of other ones.
