The high temperatures prevalent in the thermosphere (800–1000 K) have not been explained yet; [19] existing models predict a temperature no higher than about 400 K. [16] They may be caused by absorption of high-energy solar radiation (UV or X-ray), by heating from the charged particles precipitating from the Jovian magnetosphere, or by ...

The vertical temperature of the structure of the GRS is constrained between the 100–600 mbar range, with the vertical temperature of the GRS core at approximately 400 mbar of pressure [clarification needed] being 1.0–1.5°K, much warmer than regions of the GRS to the east–west, and 3.0–3.5°K warmer than regions to the north–south of ...
Jupiter and Neptune have ratios of power emitted to solar power received of 2.5 and 2.7, respectively. [27] Close correlation between the effective temperature and equilibrium temperature of Uranus can be taken as evidence that processes producing an internal flux are negligible on Uranus compared to the other giant planets. [27]
Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere. Jupiter’s Great Red Spot is different from what an Italian astronomer observed in 1665 Skip to ...
Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). [1] The close proximity to their stars and high surface-atmosphere temperatures resulted in their informal name "hot Jupiters". [2]
An anomalously high thermal flux, compared to the other Galilean satellites, was observed at an infrared wavelength of 10 μm while Io was in Jupiter's shadow. [41] At the time, this heat flux was attributed to the surface having a much higher thermal inertia than Europa and Ganymede. [ 42 ]
