Tonight's actual moon phase and image of the moon
This page shows the image of today's/tonight's actual moon phase and allows you to follow the moon phases or moon cycles as they are also called.
If you often want to see the current moon phase, or you like the night sky screensavers you can download the StarMessage screensaver
The screensaver appears automatically when you do not use your computer and shows you the current moon phase.
It will also warn you about upcoming full moon dates and new moon dates.
A waning crescent moon-sometimes called an "old moon"-is seen in the east before dawn. Now the moon has moved nearly entirely around in its orbit of Earth, as measured from one new moon to the next.
Because the moon is nearly on a line with the Earth and sun again, the "day side" of the moon is facing mostly away from us once more. We see only a slender fraction of the moon's day side: a crescent moon. Each morning before dawn, because the moon is moving eastward in orbit around Earth, the moon appears closer to the sunrise glare. We see less and less of the moon's day side, and thus the crescent in the east before dawn appears thinner each day.
The moon, as always, is rising in the east day after day. But most people won't see this moon phase unless they get up early. When the sun comes up, and the sky grows brighter, the waning crescent moon fades. Now the moon is so near the Earth/sun line that the sun's glare is drowning this slim moon from view. Still, the waning crescent is up there, nearly all day long, moving ahead of the sun across the sky's dome. It sets in the west several hours or less before sunset.
