Antares, the brightest star of the scorpion, stands near the Moon the next couple of evenings. Tonight, it is close to the upper left of the Moon at nightfall. It will be about the same distance to the right of the Moon tomorrow night.

September 9: Moon and Antares
September 10: First-Quarter Moon
The Moon is at first quarter tonight. It lines up at a right angle to the line between Earth and the Sun, so the Sun illuminates half of the lunar hemisphere that faces our way.
September 11: Zodiacal Light
If you have clear, very dark skies before dawn over the next few mornings, look toward the eastern horizon for a ghostly pyramid of light, called zodiacal light. It is sunlight reflecting off of tiny grains of dust scattered throughout our solar system.
September 12: High and Low
The curving body of Scorpius, the scorpion, and the teapot shape of Sagittarius hunker low in the south and southwest at nightfall. Cygnus, the swan, soars high overhead. And W-shaped Cassiopeia is about a third of the way up the northeastern sky.
September 13: The Lizard
Lacerta, the lizard, is in the east-northeast at nightfall, to the upper left of the Great Square of Pegasus. It passes high overhead around midnight. Its stars are all so faint that you need fairly dark skies to see any of them.
September 14: Alpheratz
For centuries, the star Alpheratz was shared by Pegasus the flying horse, and Andromeda the princess. It was his navel, and her head. It was the brightest member of both constellations. A century ago, however, it was assigned to Andromeda.
September 15: Cetus
The constellation Cetus, the whale or the sea monster, is just moving into the evening sky. It clears the eastern horizon before midnight and swims into the southwest by daybreak.
