FOR KIDS: Not seeing sunspots
What a difference! These two images of the sun’s outer atmosphere, or corona, were taken about 20 months apart. The sun is quiet in the picture at left, taken in January 1997. In the picture at right, taken in November 1998, the sun is more active. When the sun’s activity increases, more sunspots become visible.SOHO (ESA & NASA)
