1 [This is a one day old moon. More precisely, it's 1 day 15 hours and 35 minutes. That's how much time has passed from the moment of New Moon till this picture was taken. One day moons can be difficult to spot. They are very close to the horizon and visible for just a few minutes after sunset. This moon was 39 hours old but the world record young moon sighting is closer to 12 hours with a telescope and around 15 hours with binoculars. This picture was taken with a Nikon Coolpix 885 digital camera held up to the eyepiece of a Celestron C-90 Astro telescope on July 11th 2002 at 10:03 pm EDT in Holt, Michigan.  Photo by: John French, Planetarium Production Coordinator, Abrams Planetarium, Michigan State University, East Lansing, Michigan, USA]
