A major defense against everything space throws at us, Earth’s magnetic field may even protect the moon from damaging ...

Three years of radiation data collected on the far side of the moon show that Earth’s magnetic field still reaches the lunar ...

Galactic cosmic rays (GCRs) are mostly absorbed by Earth's atmosphere before they can reach the surface. However, they pose a ...

High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, ...

Learn how a flip in Earth's magnetic field may have caused changes in the radiation on our planet.

The study of cosmic ray anisotropy and magnetic fields lies at the intersection of astrophysics and plasma physics, revealing subtle imprints of the turbulent interstellar medium and the local ...

For a few hours each lunar day, the radiation environment near the moon quietly shifts. Measurements now suggest that parts ...

Primordial magnetic fields may help explain why measurements of the universe’s expansion do not agree. Scientists have long known that the universe is expanding, yet there is still no agreement on how ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those forces—magnetism—emerged in ways scientists are only now beginning to ...

Galactic cosmic rays from distant corners of the galaxy streak through your body -- as though you barely exist -- at nearly ...

We had expected that the radiation on the lunar surface would be constant when the Moon is not inside the Earth’s ...

When electronics meet cosmic rays, bad things can happen. Chip makers need to test what their products can withstand, and ...
