As another lunar month comes to a close, early risers are in for a treat. This weekend, the waning crescent moon will pass both dazzling bright Jupiter and Mars in the eastern sky.

The current cycle of moon phases started on Aug. 6 and will end when the moon is lost in the glare of the sun Thursday. As the moon travels around Earth in its orbit, it grows from a thin right-hand crescent, visible in the western sky after sunset, to a full moon. The moon has now shrunk to a left-hand crescent that's visible in the eastern sky before sunrise.

This weekend, the waning crescent moon will pass Jupiter and Mars before ending its cycle of phases. Look for the crescent moon in the eastern sky Saturday morning one hour before sunrise. It will be about 3 degrees to the right of dazzling bright Jupiter. By Sunday morning, the crescent will sit about 10 degrees to the upper right of fainter Mars.
