A proposal that diamonds may also form in Jupiter and Saturn, where the concentration of carbon is far lower, was considered unlikely because the diamonds would quickly dissolve. [16] Experiments looking for conversion of methane to diamonds found weak signals and did not reach the temperatures and pressures expected in Uranus and Neptune.
The Saturnian atmosphere is in several ways similar to that of Jupiter. It exhibits a banded pattern similar to Jupiter's, and occasionally exhibits long-lived ovals caused by storms. A storm formation analogous to Jupiter's Great Red Spot, the Great White Spot, is a short-lived phenomenon that forms with a roughly 30-year periodicity.
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.

Scientists have finally discovered how sheets of diamond rain form on the ice giants, Neptune and Uranus. The answer could explain why Neptune’s core is hot.
At a depth of 7,000 km, the conditions may be such that methane decomposes into diamond crystals that rain downwards like hailstones. [77] [78] [79] Scientists believe that this kind of diamond rain occurs on Jupiter, Saturn, and Uranus.
HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System.Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [1]
In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true.
