The decades-old theory of the layers of the Earth's ionosphere, which dates to 1931, has just received an update that takes into account the angle of the Sun.
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.
Observations of the Sun’s extended atmosphere with coronagraphs have become indispensable to both basic and applied research.
Why are coronal mass ejections from the current solar cycle wider than others? Researchers investigate.
