Scientists have suspected that this mini-magnetosphere might be involved in generating the auroras, but the connection has been unclear. (National Geographic)
Sun Bombards Earth With High-speed Wind Stream Sep 18, 2009
As a result, the planet was more affected by the Sun in 2008 than in 1996, as measured by such variables as the strength of electron fluxes in the outer radiation belt, the velocity of the solar wind in the vicinity of Earth, and the periodic behavior of auroras (the Northern and Southern Lights) as they responded to repeated high-speed streams ... The streams affected Earth's outer radiation belt, posing a threat to earth-orbiting satellites, and triggered space weather disturbances, lighting... (Science Daily)
Surprise In Earth's Upper Atmosphere Discovered Sep 11, 2009

Planets have to be about the size of Earth to be conducive for life Sep 8, 2009
Life is comfortable on Earth in part because of its relatively stable climate and its magnetic field, which deflects cosmic radiation capable of damaging organic molecules as well as producing amazing auroras. The long term stability of Earth's climate depends on the way the planet's crust is broken up into plates, which continually slide over and under one another in a process called plate tectonics.

Scientists Look Beyond Earth To Understand Auroras Jul 20, 2009
Many people think auroras are rare events, but there s almost always an aurora of some size in the sky near the poles ... Auroras are most often visible in regions bordering the Arctic Circle: Canada, Alaska, northern Greenland, the Scandinavian coast, and Siberia ... Visit the Space Weather Prediction Center s aurora Web site to view the current shape and size of the auroras around the two poles. (Science Daily)
Magnetospheric Multiscale mission enters implementation phase Jun 19, 2009
It produces many intense phenomena from solar flares to auroras to high-energy cosmic rays to X-ray emissions from the accretion disks that surround the central regions of active galaxies to sawtooth oscillations in fusion plasmas. Closer to home, it is the ultimate driver of "space weather," which impacts technologies such as communications, navigation, power grids, and astronaut health and safety.

Scientists: U.S. Not Prepared for Strong Solar Storm May 28, 2009
Solar storms can cause colorful auroras, often seen in higher latitudes on Earth. Solar storms can cause colorful auroras, often seen in higher latitudes on Earth ... There was the legendary "Carrington Event," a series of magnetic storms from the sun that hit the Earth in August and September of 1859, disrupting telegraph lines across the U.S. and triggering auroras so bright they turned the night skies into day as far south as the Caribbean. (Fox News)
Warning: Sunspot cycle beginning to rise May 9, 2009
On the plus side, the solar storms promote the colorful auroras, known as the northern and southern lights, high in the sky over polar areas. An international panel headed by Biesecker said Friday it expects the upcoming solar cycle to be the weakest since 1928. (MSNBC -- Technology)
Earth's Magnetic Field Hisses Due to Distant "Chorus" May 8, 2009

Auroras from "Space Tornadoes" Apr 30, 2009
Space Shuttle astronauts sometimes see layers of auroras over the rim of the Earth ... Ground measurements showed that the space tornadoes channel the electrical current into the ionosphere to spark bright and colorful auroras on Earth ... These currents flow along twisted magnetic field lines from space into the ionosphere where they power several processes, most notably bright auroras such as the Northern Lights, Keiling said. (SkyAndTelescope.com)
Electricity Measured Inside Space Tornadoes Apr 28, 2009
The tornadoes then channel this current of flowing electric charge along twisted magnetic field lines into Earth's ionosphere to spark bright and colorful auroras. Andreas Keiling, a space physicist at the University of California, Berkeley's Space Sciences Laboratory, presented THEMIS's findings today at the general assembly of the European Geosciences Union in Vienna, Austria.
