ESA's Solar Orbiter reveals the dynamics of the Sun's magnetic field, shedding light on the 11-year solar activity cycle.

Geophysicists in the US are proposing a new magnetic field generated in the Earth’s core, the existence of which could help us understand why our planet’s magnetic moment has flipped several times in ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t ...

Using new data gathered from sites in southern Africa, University of Rochester researchers have extended their record of Earth’s magnetic field back thousands of years to the first millennium. The ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

Lunar rocks are famously dry. They contain almost none of the volatile elements that easily escape into space, such as ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...

A small sounding rocket that launched from White Sands Missile Range in New Mexico in 2019 is now helping us understand the different layers of the sun. Mapping the magnetic fields that control those ...

New simulations offer an intriguing look into Saturn's interior, suggesting that a thick layer of helium rain influences the planet's magnetic field. New Johns Hopkins University simulations offer an ...

A rogue, planet-size object 20 light-years away from Earth has stunned astronomers with its incredibly powerful magnetic field. The scientists found that the object's magnetic field is more than 200 ...
