The composition of Jupiter's atmosphere is similar to that of the planet as a whole. [1] Jupiter's atmosphere is the most comprehensively understood of those of all the giant planets because it was observed directly by the Galileo atmospheric probe when it entered the Jovian atmosphere on December 7, 1995.

Based on Jupiter's composition, researchers have made the case for an initial formation outside the molecular nitrogen (N 2) snow line, which is estimated at 20–30 AU (3.0–4.5 billion km; 1.9–2.8 billion mi) from the Sun, and possibly even outside the argon snow line, which may be as far as 40 AU (6.0 billion km; 3.7 billion mi).
Io was confirmed to have extensive volcanic activity that is 100 times greater than that found on Earth. The heat and frequency of eruptions are reminiscent of early Earth. [160] [247] Complex plasma interactions in Io's atmosphere create immense electrical currents which couple to Jupiter's atmosphere. [160] [247]
An image shows the comet 67P/Churyumov-Gerasimenko in March 2015. New research from NASA says Jupiter-family comets like this one could have been potential sources of water for early Earth ...
A primary atmosphere is an atmosphere of a planet that forms by accretion of gaseous matter from the accretion disc of the planet's sun. Planets such as Jupiter and Saturn have primary atmospheres. Primary atmospheres are very thick compared to secondary atmospheres like the one found on Earth .
Jupiter is the largest planet in our Solar System, and the competition really isn't even close. It's an absolutely massive planet and it helped define what a gas giant planet truly is. Because of ...
The composition of Earth's atmosphere is determined by the by-products of the life that it sustains. Dry air (mixture of gases) from Earth's atmosphere contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and traces of hydrogen, helium, and other "noble" gases (by volume), but generally a variable amount of water vapor is ...
The sun, Earth and Jupiter will nearly align perfectly in the solar system on Monday, Sept. 26, during an event that happens once every 13 months called the Jupiter opposition.
