The atmosphere of Jupiter is the largest planetary atmosphere in the Solar System. It is mostly made of molecular hydrogen and helium in roughly solar proportions; other chemical compounds are present only in small amounts and include methane, ammonia, hydrogen sulfide, and water. Although water is thought to reside deep in the atmosphere, its ...
Jupiter has been visited by automated spacecraft since 1973, when the space probe Pioneer 10 passed close enough to Jupiter to send back revelations about its properties and phenomena. [ 168 ] [ 169 ] Missions to Jupiter are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v .
A planetary surface is where the solid or liquid material of certain types of astronomical objects contacts the atmosphere or outer space. Planetary surfaces are found on solid objects of planetary mass , including terrestrial planets (including Earth ), dwarf planets , natural satellites , planetesimals and many other small Solar System bodies ...
Today, four Nature papers describe new observations about Jupiter that give us a look at the planet's poles and a much better understanding of what lies underneath its surface.
Weather permitting, Jupiter will not only be brighter than most other stars and planets in the evening sky, but will also be visible all night long. Jupiter, ascending: See our solar system’s ...
The term gas giant was coined in 1952 by the science fiction writer James Blish [6] and was originally used to refer to all giant planets.It is, arguably, something of a misnomer because throughout most of the volume of all giant planets, the pressure is so high that matter is not in gaseous form.

An image of Jupiter captured by the Cassini spacecraft on Dec. 7, 2000, as the space probe made its way through the solar system toward Saturn.
Close up view of the Great Red Spot by Juno. The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anticyclonic storm that is the largest in the Solar System. It is the most recognizable feature on Jupiter, owing to its red-orange color whose origin is still unknown.
