What a lunar eclipse looks like… FROM THE MOON.
This image was taken by the Japanese lunar explorer KAGUYA. I love the description given by Phil Plait of Discover magazine’s Bad Astronomy blog:
Usually, the diamond ring effect is seen in a solar eclipse, when the Moon blocks the Sun as seen from Earth. Sunlight peaks around lunar mountains and valleys, creating what looks like a wedding ring in the sky. But not this time: that’s the Earth’s atmosphere lit up, a circle of a sunlight, a ring of a thousand simultaneous sunrises and sunsets.
This shot is actually a still frame from a video the KAGUYA probe took of the event, which can be seen here
