Diamonds are common in highly shocked ureilites, and most are thought to have been formed by the shock of the impact with either Earth or other bodies in space. [6] [8]: 264 However, much larger diamonds were found in fragments of a meteorite called Almahata Sitta, found in the Nubian Desert of Sudan.
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]
Hot atmospheres could have iron rain, [107] molten-glass rain, [108] and rain made from rocky minerals such as enstatite, corundum, spinel, and wollastonite. [109] Deep in the atmospheres of gas giants, it could rain diamonds [ 110 ] and helium containing dissolved neon.
For instance, they believe that it rains diamonds on those planets -- diamonds that sink into their interior and form a sparkly crust around their solid cores. Since it might take a long time ...
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. On Neptune and Uranus, Diamonds Rain ...
In February 2016, it was announced that NASA's Hubble Space Telescope had detected hydrogen cyanide, but no water vapor, in the atmosphere of 55 Cancri e, which is only possible if the atmosphere is predominantly hydrogen or helium. This is the first time the atmosphere of a super-Earth exoplanet was analyzed successfully.
The researchers used plastic to recreate precipitation believed to form deep inside ice giant planets Uranus and Neptune.
PSR J1719−1438 b is an extrasolar planet that was discovered on August 25, 2011, in orbit around PSR J1719−1438, a millisecond pulsar. The pulsar planet is most likely composed largely of crystalline carbon but with a density far greater than diamond. [1] [2] PSR J1719-1438 b orbits so closely to its host star that its orbit would fit ...
