Analysis of magnetic fields on the Sun's surface offers a new clue on why sunspots appear.
This summer, Earth gets a new guardian—the Deep Space Climate Observatory—to help warn astronauts and operators of critical planetary infrastructure about the Sun's raging magnetic storms.
Monitoring solar activity that disrupts communications can be helped by crowdsourced and automated reports from amateur radio operators.
Researchers show that a data processing technique could salvage useful information from raw solar observations, opening the door to improved understanding of the solar dynamo.
Faced with the prospect of a large data gap in solar irradiance records, scientists take steps to ensure that this key climate variable stays monitored.
Why are coronal mass ejections from the current solar cycle wider than others? Researchers investigate.
