Earth is the only planet that has a single moon. Photo Credit: NASA Earth is composed of four main layers, starting with an inner core at the planet's center, enveloped by the outer core, mantle ...

Things may be moving on Venus’ surface. In 1983, researchers discovered that the planet’s surface was speckled with strange, circular landforms. These rounded mountain belts, known as coronae ...

Convection processes beneath Venus' scorched surface may help explain the planet's many volcanoes, a new study reports. Venus, the hottest planet in the solar system, is estimated to have 85,000 ...

Astronomers have long debated whether Venus, which is extremely hot and inhospitable to life today, once had liquid-water oceans on its surface. A new study found very little water in the planet's ...

About 1,800 miles below Earth's surface lies a roiling region of magma sandwiched between the solid silicate-based mantle and the molten iron-rich core: the core-mantle boundary. It's a remnant of ...

Scientists have determined that Mercury, the closest planet to the sun, may contain a 10-mile thick mantle layer of diamonds based on data from NASA’s MESSENGER space probe, Space.com reported.

Using data from NASA's MESSENGER spacecraft, scientists have determined that the solar system's tiniest planet, Mercury, hides a not-so-tiny secret: a 10-mile-thick mantle of diamond.

It also means many volcanoes are direct plumes from Venus’s mantle. Where Venus is particularly dry, most water has been driven out of the planet, which also means the magma will be especially ...

Scientists have uncovered evidence linking our planet’s deep mantle structures to an ancient cosmic event. By Darren Orf Published: May 13, 2024 11:16 AM EDT Jose A. Bernat Bacete // Getty Images ...

This mysterious "Inner Core Wobble" has led them to suggest that the inner core is denser and heavier in the northwestern hemisphere, tilting it 0.17 degrees away from the planet's mantle.
