The Moon and the Sun
Date: 7 Oct 2010
This image is a view of the sun captured by NASA's Solar Dynamics Observatory on 7 Oct. 2010, while partially obscured by the moon. A close look at the crisp horizon of the moon against the sun shows the outline of lunar mountains. A model of the moon from NASA's Lunar Reconnaissance Orbiter has been inserted into the picture, showing how perfectly the moon's true topology fits into the shadow observed by SDO.
