Astrophysicists find fractal image of Sun's "storm season" imprinted on solar wind

05-25-2007 · EurekAlert!

Plasma astrophysicists at the University of Warwick have found that key information about the Sun's "storm season" is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind. This research opens up new ways of looking at both space weather and the unstable behaviour that affects the operation of fusion powered power plants.

Screaming CMEs Warn of Radiation Storms
05-28-2007 · EurekAlert!
Some CMEs also bring intense radiation storms that can disable satellites or cause cancer in unprotected astronauts. As the CME blasts through space, it plows into a slower stream of plasma blown constantly from the sun in all directions, called the solar wind. The CME causes a shock wave in the solar wind. If the shock is strong enough, it accelerates electrically charged particles that make up the solar wind to high speeds, forming the radiation storm.

Researchers identify driver for near-Earth space weather
12-11-2006 · EurekAlert!
New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth's and sun's magnetic fields connect, or merge, and not by the solar wind's electric field as was previously assumed.

Violent Past: Young sun withstood a supernova blast
05-26-2007 · Science News Online
A big bully pummeled the infant solar system, first by blasting it with a massive wind, then by exploding nearby, driving shock waves into the fledgling solar system and irrevocably altering its chemistry.

Washington University scientists analyze solar wind samples from Genesis Mission
10-29-2007 · EurekAlert!
Analyzing the mix of hydrogen, oxygen and noble gases found in the sun can answer one of the biggest questions of the universe: How did our solar system evolve?Scientists at Washington University in St. Louis and a large team of colleagues marked the beginnings of that odyssey by examining samples of solar wind for neon and argon, two abundant noble gases. The work was published in the Oct. 19, 2007, issue of Science.

Hinode mission delves into solar mysteries
12-06-2007 · EurekAlert!
New, peer-reviewed results from the Hinode space mission ("Sunrise" in English) should help explain some long-standing mysteries of the Sun, such as the huge temperature difference between its relatively cool surface and its white-hot atmosphere, and the origins of the solar wind that blasts through the solar system and buffets planetary atmospheres. These findings appear in a special collection of 10 articles, by scientists in Japan, Europe and the United States, in the Dec. 7 issue of the journal Science.
