Pushing a solar model to the highest resolution ever attempted brings order back to the Sun's magnetic tangle.

A model designed to mimic the Sun spontaneously slips into, and out of, its own grand minimum.

HAO's anniversary, which will feature a series of public events, celebrates the emergence of Boulder as a hub of solar science.

The Sun's activity waxes and wanes nearly every two years. The discovery provides clues that could help improve forecasting of solar storms, which can affect technological systems that society depends on.

A range of observing and modeling tools is helping researchers at NCAR and elsewhere discern previously unmapped links between weather events in various layers of the atmosphere, with implications for aviation, GPS, and other technology society relies on.
