Leo’s brightest star, Regulus, stands above the Moon tonight. Algieba, a binary system that marks the lion’s forehead, is farther to the upper right of Regulus.

May 24: Moon and Leo
May 25: First-Quarter Moon
The Moon is at last-quarter at 12:19 p.m. CDT. At that moment, sunlight illuminates one-half of the lunar hemisphere that faces Earth. The Moon rises in early afternoon and stands high in the southwest at nightfall.
May 26: Omega Centauri
About 160 known globular clusters orbit the center of the Milky Way galaxy. The biggest and brightest is Omega Centauri, which is low in the south in early evening. It may be the stripped core of a smaller galaxy that the Milky Way took over long ago.
May 27: Vanishing Winter
Some of the bright lights of winter are dropping from the evening sky. Low in the west at nightfall, look for Procyon in Canis Minor, the little dog. And look to its upper right for the twins of Gemini above Venus, the “evening star.”
May 28: Crowning the Crown
Corona Borealis, the northern crown, stands half-way up the eastern sky as darkness falls this evening. It is a small semicircle of moderately bright stars that opens to the left. It is crowned by a binary star system known as Alphecca.
May 29: Early Beacon
Spica is close to the right of the Moon at nightfall. The brightest star of Virgo shines blue-white, indicating that its surface is thousands of degrees hotter than the Sun’s.
May 30: Ophiuchus
Ophiuchus, the serpent bearer, is in good view tonight. The big constellation clears the eastern horizon by about 10 p.m., and arcs high across the south during the night. Most of its stars are relatively faint, so you need a starchart to find them.
