Sirius, the brightest star in the night sky, slides across the southwest this evening. The star is in the south-southwest as darkness falls and sets by around midnight. It twinkles fiercely as it drops toward the horizon.

April 3: Sirius
April 4: Moon and Gemini
The first-quarter Moon is gliding across the constellation Gemini tonight. Gemini's twin stars and the planet Mars form an arc above and to the upper left of the Moon at nightfall. Mars is the brightest member of the arc.
April 5: Moon and Mars
Mars stands close to the lower right of the Moon at nightfall. Dust on its surface gives the planet an orange tint. Pollux and Castor, the stars that represent the twins of Gemini, line up farther to the right of the Moon.
April 6: Gienah
Gienah is the brightest star of Corvus, the crow. The constellation is low in the southeast as night falls, and due south around midnight. Its brightest stars form the outline of a small sail, with Gienah at the top right corner of the sail.
April 7: Moon and Regulus
Regulus, the brightest star of Leo, the lion, is below the Moon as night falls this evening. It will stand even closer to the Moon as they set, in the wee hours of the morning.
April 8: More Moon and Regulus
The waxing gibbous Moon stares up at Regulus this evening. The bright star marks the heart of Leo, the lion. The gap between the Moon and star will increase as the night rolls by, with Regulus leading the Moon down the western sky later on.
April 9: Cat's Eye
The faint constellation Draco, the dragon, is in the northeastern sky at nightfall, and crawls high across the north later on. One of its treasures is the Cat's Eye Nebula, the glowing remains of a dying star.
