The month of May begins with Venus shining high in the western sky as an evening "star" and ends with it disappearing into the twilight. But we still have two evening "stars." Mars (in Leo, near Regulus) and Saturn (in Virgo, near Spica) are up all night. We have no morning "stars" at all until Jupiter and Venus re-emerge in June.
We do have an interesting event this month. An annular eclipse of the sun occurs in the early evening on May 20. An "annular" eclipse occurs when the Moon is too close to Earth (it reaches "perigee" on Saturday) to completely cover the sun. The eclipse will play out after the Sun sets, but we in North America will get to see it.
Constellations of note this month include Cancer (the crab), Leo (the lion), with Saturn in its midst near Regulas (the "heart of the lion"), and Virgo (the maiden), with Mars shining near Spica, and the many stars making up Hydra (the water serpent), shining in the southern sky. See you next month!
