Scientist slowly unravel 'mystery of quiet sun'

The sun has been strangely "dead" for the last year. Sunspot activity on the sun's surface reached a 95-year low, and other solar activity (solar wind, flares and eruptions) have been practically non-existent. What's going on? Two new studies (reported at New Scientist) shed light on how, but not why this is happening.

One study shows "jet stream" activity slightly below the sun's surface has slowed. (No, the study doesn't say why jet stream activity is down.) The second study reveals more details on the "arrangement of the intense magnetic tangles" within sunspots, and suggests low sunspot activity is due to a low inclination of the sun's magnetic field.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
