Monitoring and Modeling Space Weather
How do we know what kind of "weather" we're having
in space? Scientists use a network of ground-based observatories combined
with satellite-based instruments to monitor solar activity, measure
magnetic
fields, and detect many types of radiation. They also use complex computer
models to help predict the ebb and flow of space weather systems.

Research Highlights
Geologists have found evidence that sea ice extended to the equator 716.5 million years ago, bringing new precision to a "snowball Earth" event long suspected to have taken place around that time. Funded...
