The Sun is our closest star and from a distance it seems unchanging. The Sun is not a calm object though. A close look at the surface gives it the impression of boiling soup. We can see hot gas trapped in giant magnetic loops arching over its surface. We also see occasional, highly energetic eruptions blast from its surface. The Sun interacts with the Earth in familiar ways, such as producing colorful auroras, and occasionally also produces dramatic far reaching effects, such as the Quebec Blackout in 1989. This Teen Science Cafe will highlight some of the common and uncommon events produced by the Sun.
