SDO's Science

The Heliospheric and Magnetic Imager (HMI)Dean Pesnell, the SDO Project Scientist, explains how the Helioseismic and Magnetic Imager (HMI) instrument will allow us to see activity inside the sun and even on the other side of the sun.For complete transcript, click here.

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.For complete transcript, click here.

The Atmospheric Imaging Assembly (AIA)SDO Project Scientist Dean Pesnell explains how the SDO's Atmospheric Imaging Assembly (AIA) instrument suite will allow us to take pictures of the sun at multiple temperatures and at resolutions never before seen. For complete transcript, click here.
