For a few hours each lunar day, the radiation environment near the moon quietly shifts. Measurements now suggest that parts ...
High-energy particles called galactic cosmic rays (GCRs) bombard unprotected objects in space, often causing damage. Earth, ...

Cassini data suggests Saturn’s magnetic bubble is lopsided vs. Earth’s
A new study built on six years of NASA Cassini spacecraft observations has found that Saturn’s magnetosphere, the giant ...
The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...
Our Sun is far from a smooth, white ball in the sky. Twisting and looping magnetic field lines rise from its surface like hair, causing dark, transient patches on the surface called sunspots wherever ...

Astronomers revisit how young galaxies built magnetic fields
Researchers studying a distant spiral galaxy have found that large-scale, ordered magnetic fields existed far earlier in cosmic history than standard theories predicted, forcing a fresh look at how ...
Hundreds of millions of years ago, Earth’s magnetic field behaved in a way that has long baffled scientists, showing wild and ...
Researchers have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation ...
