Screaming CMEs Warn of Radiation Storms (NASA Feature)
A
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.

Get
Ready to Explore the Heart of the Sun (SOHO Mission News)
Scientists

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.
