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.
An alternative possibility is that 55 Cancri e is a solid planet made of carbon-rich material rather than the oxygen-rich material that makes up the terrestrial planets in the Solar System. [25] In this case, roughly a third of the planet's mass would be carbon, much of which may be in the form of diamond as a result of the temperatures and ...
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.

WASP-12b is a hot Jupiter [6] (a class of extrasolar planets) orbiting the star WASP-12, discovered in April of 2008, by the SuperWASP planetary transit survey. [7] [1] The planet takes only a little over one Earth day to orbit its star, in contrast to about 365.25 days for the Earth to orbit the Sun.
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]
