In the hours following sunset on Saturday (June 28), the waxing crescent moon will line up with Mars and the bright star Regulus above the western horizon — before swiftly slipping out of view.
Stargazers in the U.S. will find the slender form of the crescent moon roughly 20 degrees above the western horizon right at sunset on Saturday. The following hour will see Mars and the bright star Regulus line up to the upper left of the lunar disk, becoming visible as dusk gives way to the coming night.
