April 30: Alphecca
April 29: Last-Quarter Moon
The Moon reaches last quarter at 10:29 p.m. CDT. At first and last quarter, the Moon looks as though it were sliced through from top to bottom like a ripe melon. Half of the side facing Earth is in sunlight, while the other half is in shadow.
April 28: Evening Stars
Some of the brightest stars in the night sky are in view early this evening. Sirius, the brightest of all, is low in the southwest at nightfall. Bright orange Betelgeuse is well to its upper right, with Aldebaran to the lower right of Betelgeuse.
April 27: Evening Constellations
Several famous constellations highlight this evening’s sky. At nightfall, the “twins” of Gemini stand almost straight up in the west. Leo, the lion, is high in the south, while Virgo and Hercules are just climbing into view in the east.
April 26: Spring Triangle
A widespread triangle of bright stars is in view in the east this evening. An hour after sunset, look in the east for yellow-orange Arcturus. Well to its lower right is blue-white Spica, with Regulus well above them, beyond the even brighter planet Jupiter.
April 25: More Moon and Planets
Look for the planet Saturn to the lower right of the Moon at first light tomorrow. It looks like a bright golden star. The even brighter planet Mars is about the same distance to the lower right of Saturn.
April 24: Moon and Planets
The Moon forms a quartet with a bright star and two bright planets early tomorrow. Mars is close to the lower right of the Moon. Antares, the star at the heart of the scorpion, is farther to the lower right, with the planet Saturn to the lower left of the Moon.
