Magnetic Bubbles on the Moon Reveal Evidence of "Sunburn"
Every object, planet or person traveling through space has to contend with the Sun's damaging radiation -- and the Moon has the scars to prove it. Research using data from NASA's ARTEMIS mission — short for Acceleration, Reconnection,...

NASA | Solar Hurricane Tears Off Tail of Comet Encke
NASA's STEREO satellite captured the first images ever of a collision between a solar "hurricane", called a coronal mass ejection (CME), and a comet. The collision caused the complete detachment of the comet's plasma tail. Scientists...

NASA | The Sun Reverses its Magnetic Poles
This visualization shows the position of the sun's magnetic fields from January 1997 to December 2013. The field lines swarm with activity: The magenta lines show where the sun's overall field is negative and the green lines show where...

Why Do Power Lines Buzz?
The buzzing sound that power lines produce is caused by corona discharge. Corona discharge is an electrical discharge that occurs when a fluid (like air) surrounding an electrically-charged conductor becomes ionized. In simple terms,...

How the Northern Lights are formed
Ongoing geomagnetic storms have led to sightings of the Northern Lights across North America this week, the result of a coronal mass ejection from the Sun that occurred on Sunday, sending a stream of charged particles toward Earth.

Ocean Tides and Magnetic Fields
Seawater is an electrical conductor, and therefore interacts with Earths magnetic field. As the tides cycle around the ocean basins, the ocean water essentially tries to pull the geomagnetic field lines along. Because the salty water is...
