NASA - Dynamic Earth

A giant explosion of magnetic energy from the Sun, called a coronal mass ejection, slams into and is deflected completely by the Earth's powerful magnetic field. The Sun also continually sends out streams of light and radiation energy. Earth's atmosphere acts like a radiation shield, blocking quite a bit of this energy.

Much of the radiation energy that makes it through is reflected back into space by clouds, ice and snow and the energy that remains helps to drive the Earth system, powering a remarkable planetary engine – the climate. It becomes the energy that feeds swirling wind and ocean currents as cold air and surface waters move toward the equator and warm air and water moves toward the poles – all in an attempt to equalize temperatures around the world.

[VIDEO] - NASA | A Big Blast

A beautiful prominence eruption producing a coronal mass ejection (CME) shot off the east limb (left side) of the sun on April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT. The CME was not aimed toward Earth.

Listening to Solar Storms

This sonification of the recent solar storm activity turns data from two spacecraft into sound. It uses measurements from the NASA SOHO spacecraft and the University of Michigan's Fast Imaging Plasma Spectrometer (FIPS) on NASA's MESSENGER spacecraft at Mercury. The creator is Robert Alexander, a design science doctoral student at the University of Michigan and NASA fellow.
