 | Shrinking Atmospheric Layer Linked to Low Levels of Solar Radiation
Source: NSF Posted: 9/3/2010
Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere. Results of a study link a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels.

 | Extended Solar Minimum Linked to Changes in Sun’s Conveyor Belt
Source: UCAR Posted: 8/17/2010
A new analysis of the unusually long solar cycle that ended in 2008 suggests that one reason for the long cycle could be a stretching of the Sun’s conveyor belt, a current of plasma that circulates between the Sun’s equator and its poles.
