Back To Wild

Twin NASA spacecraft that are studying the sun have sent back spectacular first images of Earth that will help the scientists detect and track solar storms.This picture gives a close-up view of the sun’s activity, like the snapshot of loops in a magnetically active region that soon afterward produced a series of intense flares.

Scientists say that this sweeping viewpoint will let them study the flow of energy from the sun to Earth, coronal mass ejections—violent eruptions of electrically charged gas from the sun’s atmosphere that can cause dangerous solar storms.
