NASA scientists answer some common questions about the sun, space weather, and how they affect the Earth. This is a two-part series.

Part Two addresses:

1. Do all flares and CMEs affect the Earth?

2. What happens when a flare or CME hits the Earth?

3. How quickly can we feel the effects of space weather?

4. Why are there more flares and CMEs happening now?

For more information about all these questions and more, visit NASA's Space Weather FAQ. http://www.nasa.gov/mission_pages/sun...
