Heads up, stargazers! The waxing gibbous moon will shine close to the red star Antares after sunset on Sunday (Aug. 3).
Look 20 degrees above the southern horizon to find the 69%-lit moon glowing among the stars of the constellation Scorpius, with Antares appearing as a bright, reddish point of light roughly 1 degree to the upper left of the lunar disk. Remember: The tip of your finger held at arm's length accounts for approximately 1 degree of the night sky.
