Thin Crescent Moon   HOME INDEX BACK NEXT

The Moon makes one revolution of the Earth in about 29 days. The "age" of the Moon in any given cycle is measured from the time of the New Moon, when the Moon is directly between the Earth and the Sun. Measured in this way, this image shows a 2-day-old moon. It was visible as a thin crescent in the western sky just after sunset.

Image details: A mosaic of two images, one of the north half and another of the south half.  Both halves were based on 10 stacked images, each 1/250th of a second at ISO 1600.
