By Dr. Tony Phillips - Science@NASA If you've ever stood in front of a hot stove, watching a pot of water and waiting impatiently for it to boil, you know what it feels like to be a solar physicist. Back in 2008, the solar cycle plunged into the deepest minimum in nearly a century. Sunspots all but vanished, solar flares subsided, and the sun was eerily quiet. "Ever since, we've been waiting for solar activity to pick up," says Richard Fisher, head of the Heliophysics Division at NASA...

Sometimes a problem is so big, one country cannot handle it alone. That's the message scientists are delivering at today's International Living with a Star (ILWS) meeting in Bremen, Germany, and representatives from more than 25 of the world's most technologically-advanced nations have gathered to hear what they have to say. "The problem is solar storms"”figuring out how to predict them and stay safe from their effects," says ILWS Chairperson Lika Guhathakurta of NASA headquarters. "We...

The sun is the largest and most important object in our solar system, containing 99.8% of the solar system's mass, or quantity of matter. Among that remaining 0.2% are hot planets, icy moons, asteroid belts, chunks of rock, rings of ice, and over 100 worlds -- including our Earth. The "space" in between is a mesmerizing mix of the push-and-pull of gravity, solar winds, particle radiation, and magnetospheres. Not bad for a mere 0.2%! On Thursday, July 1, scientist Jonathan Cirtain from NASA's...
