Scientists at NCAR and CfA follow South American eclipse in NSF/NCAR research aircraft.

A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash.

In a sign of the far-ranging effects of space weather, new research shows that a major 1972 solar storm caused the explosions of more than two dozen sea mines.

Scientists, in a major computer modeling achievement, simulate the influence of CO2 through Earth's entire atmosphere

The solar seasons — which change every six to 18 months from "bursty" to quiet, and vice versa — have been realistically simulated for the first time in a computer model.
