Scientists discovered tiny jets on the Sun that power both fast and slow solar wind. These jets eject particles and shape ...

This week, see what makes loggerhead sea turtles “dance,” track a cosmic “ghost particle,” uncover an ancient basilica, and ...

Non-mixing layers of water and hydrocarbons thousands of miles deep could explain the icy planets’ strange magnetic fields.

Geomagnetic storms also cause problems on Earth. The electric currents they create can overload power plants and cause ...

Earth's magnetic field dramatically flipped a little more than 40,000 years ago. We can now experience this epic upheaval, ...

It's a key problem that will need to be addressed if humans are to attempt deep-space, long-duration missions. Not only is radiation exposure a dangerous health risk to humans, but it also poses a ...

There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when electrical current flows through it. The last time the scientists who operate ...

"We were very surprised to see that the same tiny plasma jets appear to be driving both the fast and the slow solar wind." ...

The above 40-second video is sped-up footage of the new-found jets flashing briefly near the Sun’s south pole. In reality, ...

A NASA satellite that suddenly reappeared after going silent gets credit for the remarkable discovery—a pair of temporary ...

Radiation belts are a normal part of the architecture of a planet with a global magnetic field. Stars are constantly leaking particles, borne by a stellar wind; these stream out and, where they ...

Solar Orbiter has revealed that tiny, hair-like jets in the Sun’s coronal holes are responsible for both fast and slow solar ...
