This image is a view of the sun captured by NASA's Solar Dynamics Observatory on Oct. 7, 2010, while partially obscured by our moon. A close look at the sharp edge 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 topology fits into the shadow observed by SDO.
