New images of the sun from NASA’s SDO

The SunThis is one of the first images sent to Earth from the Solar Dynamics Observatory (SDO) last week. The SDO satellite collects data and images of the sun, producing enough material to fill a CD every 36 seconds.

Most satellites share ground stations, but because of the monster processing power needed to store all this data, the SDO has one all to itself. Located in New Mexico, the ground station is in constant communication with the satellite. The satellite is in geosynchronous orbit, which means it rotates at the same speed as Earth and is always directly above the ground station.

In its voyage of five years, the SDO hopes to understand how and why the sun’s magnetic field changes. From that they hope to predict the solar winds near Earth, which can have drastic effects on technology. They might also learn to forecast the weather in space, potentially lifesaving for astronauts.

The images it has received so far are stunning. Even if the SDO doesn’t unveil all the mysteries of the sun, the mission will not be a failure. Click through for more images from the SDO.
