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.
Falling diamond dust (Inari, Finland) Diamond dust is similar to fog in that it is a cloud based at the surface; however, it differs from fog in two main ways. Generally fog refers to a cloud composed of liquid water (the term ice fog usually refers to a fog that formed as liquid water and then froze, and frequently seems to occur in valleys with airborne pollution such as Fairbanks, Alaska ...
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.
High pressure experiments predict that large quantities of diamonds condense from methane into a "diamond rain" on the ice giant planets Uranus and Neptune. [83] [84] [85] Some extrasolar planets may be almost entirely composed of diamond. [86] Diamonds may exist in carbon-rich stars, particularly white dwarfs.
They recreated Neptune's conditions at Stanford's SLAC Laboratory and successfully observed the formation of diamond rain, thanks to the help of some very powerful lasers. Scientists recreate ...
The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds in the upper troposphere (5–10 km (3.1–6.2 mi)), but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals are responsible for the type of ...
They were found on a mountain pass frequented by Vikings 1,000 years ago, researchers said. ‘Exceedingly rare’ ancient tools found under melting ice in Norway, researcher says Skip to main content
