The crescent moon will shine close to the gas giant Jupiter in the morning sky on July 23, with its shadow-veiled disk softly lit by sunlight reflected off Earth's surface, a ghostly effect known as Earthshine
Look east around 4 a.m. local time, just before dawn, to see the slender form of the crescent moon climb above the horizon. Jupiter, appearing as a bright "star" will sit about 5 degrees to the right of the moon — roughly the combined width of your index, middle and ring fingers held at arms length against the night sky!
