A major scientific breakthrough has settled a decades-old debate about the moon’s interior. Researchers have confirmed that the moon has a solid inner core, similar to Earth’s, composed of iron with a ...

New research reveals that the Moon's core has a density similar to that of iron. This discovery may resolve long-standing discussions about the Moon's internal structure and contribute to a deeper ...

The movement of atoms in the liquid outer core generate the Earth's magnetic field and the planet's broad habitability. But while the center of our planet has long been thought to be a solid iron ...

Its loss from magma suggests that the planet has a deep reservoir of primordial helium, and the new compounds suggest that Earth’s iron-rich core could hold some of that helium. But the team ...

The researchers say the Earth’s true core is iron because of the “ricochets” they uncovered. It’s an intriguing discovery, and one that the paper outlines very well. If it does indeed ...

A coil with an iron core is called an electromagnet. The iron core increases the coil’s magnetic field strength. A simple electromagnet is made by coiling wire around an iron nail. An iron core ...
