High pressure experiments suggest large amounts of diamonds are formed from methane on the ice giant planets Uranus and Neptune, while some planets in other planetary systems may be almost pure diamond. [2] Diamonds are also found in stars and may have been the first mineral ever to have formed.
The researchers used plastic to recreate precipitation believed to form deep inside ice giant planets Uranus and Neptune. Diamonds rain from the sky on billions of planets, new research shows Skip ...
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.
The extreme pressure and temperature deep within Uranus may break up the methane molecules, with the carbon atoms condensing into crystals of diamond that rain down through the mantle like hailstones. [86] [87] This phenomenon is similar to diamond rains that are theorised by scientists to exist on Jupiter, Saturn, and Neptune.
This envelope reaches temperatures of 10,000 K. The planet is estimated to be losing (1–5) × 10 8 kg of hydrogen per second. This type of atmosphere loss may be common to all planets orbiting Sun-like stars closer than around 0.1 AU. [54] In addition to hydrogen, carbon, and oxygen, HD 209458 b is thought to have water vapor in its atmosphere.

[58] [59] In Māori, the planet is called Tangaroa, named after the Māori god of the sea. [60] In Nahuatl, the planet is called Tlāloccītlalli, named after the rain god Tlāloc. [60] In Thai, Neptune is referred to by the Westernised name Dao Nepchun/Nepjun (ดาวเนปจูน) but is also called Dao Ket (ดาวเกตุ, lit.
It is possible to predict the forms of sun dogs as would be seen on other planets and moons. Mars might have sun dogs formed by both water-ice and CO 2-ice. On the giant planets—Jupiter, Saturn, Uranus, and Neptune—other crystals form clouds of ammonia, methane, and other substances that can produce halos with four or more sun dogs. [9]
