The Van Allen Probes began an extended mission in November to advance understanding of Earth's radiation belts.
Models based on the Sun's polar magnetic fields performed best in simulating the solar cycle and predicting solar behavior.
A new model of how the Sun's 11-year cycle affects climate leads to slight changes in model results on atmospheric chemistry, but temperature and wind results are consistent with the previous model.
Why are coronal mass ejections from the current solar cycle wider than others? Researchers investigate.
