Mercury, the smallest planet in our solar system, has a magnetic field that has intrigued scientists for decades. Recent observations indicate that this magnetic field is weakening, prompting ...

The sun continuously blasts charged, magnetic field-carrying particles, or plasma, in all directions. This solar wind ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

(Nanowerk News) Paleomagnetic analysis of 28 particles from the asteroid Ryugu has provided the most detailed evidence yet of magnetic fields present in the early solar system. A research team led by ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

Here’s what you’ll learn when you read this story: It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field.

An SwRI-led study identified particles accelerated to extremely high energies by magnetic reconnection near the Sun. As NASA’s Parker Solar Probe (trajectory shown in green) crossed the heliospheric ...

Voyager 1, launched in 1977, has traveled farther than any spacecraft in human history. After more than four decades of silent endurance through space, it now sails beyond the orbit of the outer ...
