Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...
Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core. It's believed to play an important role in maintaining the planet’s ...
As iron is the primary component of the Earth's core, its properties (e.g., its melting temperature at the pressures found in the proximity of the Earth's inner core boundary) set an upper limit ...
Previous seismic studies revealed that the inner core is solid metal and rotates within a super-hot molten outer core, also mostly made of metal, including iron and nickel. Researchers have ...
