In this episode of Cool Science Radio Dan Seaton joins the conversation about the relationship between and sun and the earth. Dan is a University of Colorado NOAA Scientist. The words "Space Weather" may conjure up images of intergalactic tornadoes and star filled blizzards, but it actually refers to the electrically charged particles and radiation from the sun. After a few quiet years, our sun is once again rampining up with activity. What does that mean for us here on earth?
