Millions of people on Earth witnessed the transit of Mercury on Nov. 11, 2019, when the tiny black form of the first planet crossed the face of the sun. The best views were out of this world--literally. More than 22,000 miles above Earth's surface, NASA's Solar Dynamics Observatory (SDO) recorded an incredible movie of the transit. This movie is unlike any recorded on Earth. High above our planet's atmosphere, extreme ultraviolet telescopes onboard SDO were able to see Mercury making first contact with the sun's outer atmosphere, the corona. The wavelengths required to gain this view are blocked by air and only visible from space.
