Earth’s magnetic field is constantly swirling and shifting thanks to a colossal ocean of liquid metal sloshing around in its ...

One of the biggest arguments about the inner solar system among astronomers and scientists is why exactly Mercury has such a massive iron core. The prevailing theory is that collisions with other ...

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

Scientists from Tohoku University and the University of Maryland have pinpointed the strong magnetic field of the early sun as the reason behind the radial variation of rock and metal in rocky planets ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

Researchers led by the University of Maryland have found that the sun's magnetic field is the reason behind the large size of Mercury’s iron core. The study has been published in Progress in Earth and ...

Beneath the Earth’s surface lies the core, a scorching sphere of iron surrounded by a layer of molten metal. Temperatures at the core reach approximately 6,000°C (10,800°F), comparable to the surface ...

Learn about the continent-sized rocks hidden deep within Earth's mantle that have influenced the magnetic field for millions ...

This shifts our entire perspective on what makes a planet “Earth-like.” Nature is far more creative than our own solar system suggests. The universe might be teeming with “magma-shielded” worlds that ...

A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run ...
