The Night Sky

Friday, August 29The Moon is coming back into the evening sky. Look for the waxing crescent low in the west-southwest in twilight, as shown at lower right. Can you make out Spica twinkling beneath it? Binoculars help. Far to their upper left are Saturn and Mars.

Saturday, August 30The waxing crescent Moon now shines closer to Saturn and Mars, as shown above. Can you see little Alpha Librae in the middle of the narrow triangle they make?

Sky & Telescope

Sunday, August 31Spot the Moon at dusk with Saturn to its right and Mars to its lower left (for North America).As the stars come out this week, the first you see may be Arcturus shining high in the west. As the sky gets a little darker, look to its right for the Big Dipper scooping down in the northwest.

Monday, September 1First-quarter Moon this evening and Tuesday evening (exactly first quarter at 7:11 a.m. Eastern Daylight Time Tuesday morning). It's passing over Scorpius, as shown in the image above.
