The liquid outer core, which extends to 1,795 miles above the solid core, Koper says, produces a protective field of magnetic energy. The molten metal cools as it approaches Earth’s rocky mantle ...

The outer core, with a radius of approximately 2,200 kilometers, is believed to be composed mostly of a liquid iron-nickel alloy, formed by heavy elements sinking towards the center of the Earth.

Two new innovative methods describe how to measure the electrical resistivity of liquid iron -- such as that found in planetary cores -- at extremely high pressures and temperatures. Prior to this ...

Earth's core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Trillions of galaxies and more space headlines 08:19. On one particularly hot planet, hundreds of light-years away from Earth, the forecast is cloudy with a chance of liquid iron rain.

Astronomers have spotted an unexpected chemical element high within the atmosphere of two sizzling exoplanets where liquid iron and gems rain down from the skies.. The two exoplanets, which orbit ...

The planet is believed to have frequent rains, but the material falling from the skies isn’t water… it’s liquid iron. The planet is known as WASP-76b, and it’s totally wild.
