Screaming CMEs Warn of Radiation Storms (NASA Feature)
CME (Coronal Mass Ejection) is a solar body slam to our high-tech
civilization. CMEs begin when the sun launches a billion tons
of electrically conducting gas (plasma) into space at millions
of miles per hour. A CME cloud is laced with magnetic fields,
and CMEs directed our way smash into Earth's magnetic field.
A Breakthrough in Solar Storm Forecasting (NASA Feature)
scientist using the Solar and Heliospheric Observatory (SOHO)
has found a way to forecast solar radiation storms. The new method
offers as much as one hour advance warning, giving astronauts
time to seek shelter and ground controllers time to safeguard
their satellites when a storm is approaching.
Ready to Explore the Heart of the Sun (SOHO Mission News)
may have at last found a way to explore the heart of the sun with
the detection of a special type of wave generated deep in the
solar interior. The heart, or core, of the sun is the location
of the sun's nuclear furnace, where fusion reactions power the
sunlight that supports almost all life on Earth.
