These animations and web shorts explain how SDO's instruments will look at the sun and allow us to better predict how the sun will affect us in the future.

The Extreme Ultraviolet Variability Experiment (EVE)

Dean Pesnell explains how the The Extreme Ultraviolet Variability Experiment (EVE) instrument will allow us to better measure solar irradiance in extreme ultraviolet wavelengths. This type of irradiance, which is absorbed completely by Earth's upper atmosphere, can be dangerous to astronauts and electronics in space. It can also heat up and expand the outer atmosphere, potentially causing satellites to fall out of orbit.
