A powerful geomagnetic storm recently compressed Earth’s outer plasma shield so dramatically that satellites found themselves ...

NASA detects first “magnetic switchback” near Earth: an energetic change in your space shield that reveals new solar risks.

Since 1611, humans have recorded the comings and goings of black spots on the sun. The number of these sunspots waxes and wanes over approximately an 11-year cycle — more sunspots generally mean more ...

Voyager 1 and 2 traveled billions of miles to reach the heliopause, showing how the Sun's magnetic influence marks the ...

New data gleaned from the magnetic sensor aboard NASA's InSight spacecraft is offering an unprecedented close-up of magnetic fields on Mars. In a study published today in Nature Geoscience, scientists ...

Scientists report a method to study smaller magnetospheres, sometimes just millimeters thick, in the laboratory. The new experimental platform combines the magnetic field of the Large Plasma Device ...
