An Airplane in Front of the Moon
If you look closely at the Moon, you will see a large airplane in front of it. Well, not always. OK, hardly ever. Actually, to capture an image like this takes precise timing , an exposure fast enough to freeze the airplane and not overexpose the Moon -- but slow enough to see both, a steady camera, and luck -- because not every plane that approaches the Moon crosses in front. Helpful equipment includes a camera with fast continuous video mode and a mount that automatically tracks the Moon . The featured fleeting superposition was captured from Seoul , South Korea two weeks ago during a daytime waxing gibbous moonrise. Within 1/10th of a second, the airplane crossing was over .
