NASA's Solar Dynamics Observatory (SDO) has begun its mission to unravel the secrets our sun is holding close to its heart. In many ways our nearest star remains a mystery, but using its high-definition eyes the SDO will detect solar phenomena, aid space weather prediction methods and safeguard our way of life from potentially damaging solar flares.

As we depend more on sensitive electronics, solar storms could knock out communication networks and power grids. Now that NASA's Solar Dynamics Observatory is looking out for us, what are its key scientific objectives?

The most advanced solar observatory ever built rocketed into space Thursday on a five-year quest to shed light on Earth's star.

As the Solar Dynamics Observatory launched atop the Atlas V rocket, photographer Tony Hoffman spotted a beautiful atmospheric phenomenon in his lens. However, this "sundog" didn't last for long.

NASA hopes the Solar Dynamic Observatory will turn its scientists into space weathermen.

NASA is preparing to launch an orbital observatory that can pick apart the inner workings of the sun.
