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, ...

Iron is the most abundant element by mass on Earth. Despite being so common and well-studied, iron still manages to puzzle scientists by exhibiting electric and magnetic behaviors that are not fully ...

The Earth’s inner core is incredibly tricky to study, since it’s buried beneath thousands of miles of rock. New seismic studies suggest that it’s not just a solid ball of iron, as has been assumed, ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.

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 ...

RICHLAND, Wash.— A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy’s ...

Though Earth's innermost core is solid, new research suggests that it hosts a lot of variation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
