Three years ago today—Feb. 11, 2010—NASA launched the most sophisticated and capable Sun watcher in history: SDO, the Solar Dynamics Observatory. Equipped with a huge range of detectors, SDO has kept an unblinking eye on the Sun 24 hours a day for over 1000 days now.
It has returned to Earth valuable data on our tempestuous star, including pictures that wring dry my supply of adjectives. Jaw-dropping. Mind-blowing. Spectacular.
In its honor, NASA’s Goddard Space Flight Center put together a simply gorgeous and moving video about SDO. Take the time to soak this in; make sure it’s set to the highest definition and make it full screen.
