Odd Auroral Arc Crosses Rather Than Circling The North Pole
For something as dynamic as the aurora borealis, acting up is normal. But even it can behave in ways that are simply odd. Scientists using the Ultraviolet Imager aboard NASA's Polar Spacecraft can observe the aurora borealis on the day and night side while the spacecraft is over the northern hemisphere. At today's meeting of the American Geophysical Union in Boston, they report on their observation of unusual transpolar auroral arcs, possibly fed by the onset of solar storms. (1998-05-28)

NASA researcher finds planet-sized space weather explosions at Venus
Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day. (2014-02-20)

(2008-12-12)

Topsy-turvy motion creates light switch effect at Uranus
A Georgia Tech study suggests Uranus' magnetosphere, the region defined by the planet's magnetic field and the material trapped inside it, gets flipped on and off like a light switch every day as it rotates along with the planet. It's 'open' in one orientation, allowing solar wind to flow into the magnetosphere; it later closes, forming a shield against the solar wind and deflecting it away from the planet. (2017-06-26)

Observing the Birkeland currents
When the supersonic solar wind hits the Earth's magnetic field, a powerful electrical connection occurs with Earth's field, generating millions of amperes of current that drive the dazzling auroras. These so-called Birkeland currents connect the ionosphere to the magnetosphere and channel solar wind energy to Earth's uppermost atmosphere. Solar storms release torrential blasts of solar wind that cause much stronger currents and can overload power grids and disrupt communications and navigation. (2014-10-06)

Teamwork: IBEX and TWINS observe a solar storm
On April 5, 2010, the sun spewed a two-million-mile-per-hour stream of charged particles toward the invisible magnetic fields surrounding Earth, known as the magnetosphere. As the particles interacted with the magnetic fields, the incoming stream of energy caused stormy conditions near Earth. Some scientists believe that it was this solar storm that interfered with commands to a communications satellite, Galaxy-15, which subsequently foundered and drifted, taking almost a year to return to its station. (2012-04-12)
