How Scientists Are Tackling the Tricky Task of Solar Cycle Prediction
Scientists have struggled to accurately forecast the strength of the sun’s 11-year cycle — even after centuries of solar observations.
Tiny Jets on the Sun Power the Colossal Solar Wind
A new analysis argues that ubiquitous eruptions in the sun’s corona explain the vast flow of charged particles seen streaming out through the solar system.
Strange Solar Gamma Rays Discovered at Even Higher Energies
There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on.
Planets Found to Be Larger Than the Disks They Come From
The new finding is challenging established theories of how planets come to be.
Eclipse Hunter Reveals the Science That Can Only Be Done in the Dark
Even in the age of sun-observing satellites, astronomers like Jay Pasachoff still seek out total solar eclipses for the tales they can tell about our sun.
