Solar Minimum

Sunspots are normal -- they're regions of dark, cool and highly magnetized regions on the Sun's surface. Normal solar activity accompany sunspots -- such as flares, which give us auroras, knock out power supply and fry astronauts. Last week however, sunspots disappeared. There were none. This apparently is the signal for a solar minimum, a period when solar activity subsides. It could last anywhere from 9-14 years. If you ever wanted to go spacewalking, now's the time to do it!
