Roughly 35 million years ago, a massive asteroid slammed into the Atlantic Ocean near what’s now the East Coast. The impact ...

Crystals are everywhere. With few exceptions, the solid inorganic substances that make up our world are crystalline. This includes rocks, minerals, ceramics and metals.

Over a thousand miles from the surface, in Earth’s D” layer—right on the edge of the liquid metal outer core—there is a weird ...

The crystal chemistry of these minerals is governed by the interplay between the tetrahedral silicate units and various titanium-based polyhedra – often octahedral – that influence the ...

Meanwhile, the scientists believe the reaction would also spark silicate crystals. These would migrate toward the mantle, creating a dense layer of silica wrapping the core, per the press release.

1 It’s all about the rhythm: Crystals are repeating, three-dimensional arrangements of atoms, ions, or molecules. 2 Almost any solid material can crystallize—even DNA. Chemists from New York ...

Pallasites contain big, beautiful olive-green crystals - a form of magnesium-iron silicate called olivine - embedded entirely in metal. Sometimes the olivine does not occur as a single crystal but as ...

The spectrum, which separates the light from the object into its component wavelengths, provides a wealth of information, including evidence of a dynamic atmosphere with clouds of silicate crystals ...

For example, zircons are simple silicate crystals that date back to the time before life started. A zircon found in Australia ...

Thousand-mile-per-hour winds are blowing a hail of tiny quartz crystals through the silicate-enhanced, scorching hot atmosphere of a distant gas giant planet called WASP-17b, the James Webb Space ...
