The Great Red Spot could help scientists explain why Jupiter’s upper atmosphere is much warmer than you might expect.
It is the conclusion that researchers at the Center for Space Physics at Boston University in the United States, described in the journal Nature on unusually high values observed in the upper atmosphere of Jupiter.
Sunlight warms the Earth effectively reaching the Earth’s atmosphere at altitudes well above the south side, even at 250 miles high, for example, where orbiting International Space Station. Jupiter is more than five times as distant from the Sun, and yet has its upper atmosphere temperatures, on average, comparable to those found on Earth.
With solar heating from above discarded, designed observations to map the distribution of heat around the planet in search of possible temperature anomalies that could give clues as to where the energy comes, “says the study’s lead author, James O ‘Donoghue, scientist BU
Scientists studying the processes in the outer solar system have had difficulty determining the sources of solar energy not responsible for this additional heating.

Astronomers measure the temperature of a planet by observing infrared (IR) light emitting invisible. The tops of the clouds we see visible on Jupiter are about 30 miles above its edge; infrared emissions used by the BU team came from heights of 500 miles higher. When BU observers looked at their results, they found high temperatures much larger than ever anticipated that his telescope looked at certain latitudes and longitudes in the southern hemi-sphere of the planet altitudes.
The Great Red Spot of Jupiter (GRS for short) is one of the wonders of our solar system. Discovered after years since the introduction of telescopic astronomy in the seventeenth century by Galileo, its gases swirling pattern of color often called “perpetual hurricane.” The GRS has varied in size and color throughout the centuries, extending for a distance equal to three Earth diameters, and has winds take six days to complete a lap. Jupiter rotates very quickly, completing a lap in just ten hours.
Solving an “energy crisis” on a distant planet has implications within our solar system as well as for planets orbiting other stars. As scientists BU, unusually high temperatures well above target visible disc of Jupiter is not a single aspect of our solar system. The dilemma also occurs on Saturn, Uranus and Neptune, and probably in all giant exoplanets outside our solar system.
