Saturn moon Enceladus hides a giant invisible electromagnetic web
NASA’s Cassini spacecraft detected an electrical circuit linking Saturn to its small moon Enceladus, revealing an invisible electromagnetic structure that stretches across hundreds of thousands of ...
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 ...
