5. The Night Sky Sky & Telescope Tuesday, March 25 The biggest and brightest asteroids, 1 Ceres and 4 Vesta respectively, are only about 2° apart in eastern Virgo in the early morning hours, some 12° northeast of Mars. They've brightened to magnitudes 7.3 and 6.1, respectively. They'll be at opposition in mid-April. Wednesday, March 26 As dawn brightens on Thursday morning the 27th, you'll find Venus near the thin waning crescent Moon, as shown here. Thursday, March 27 On the traditional divide between the winter and spring sky is the dim constellation Cancer. It's between Gemini to its west and Leo to its east. Cancer holds a unique object: the Beehive Star Cluster, M44, in its middle. The Beehive shows to the naked eye as a dim, cloudy glow if your sky is fairly dark. Look for it a little less than halfway from Pollux to Regulus. With binoculars it's a snap even in a polluted sky. Friday, March 28 The huge, bright Winter Hexagon nearly fills the southwestern sky at dusk. Start with bright Sirius in the south, marking the Hexagon's lower left corner. High above Sirius is Procyon. From there look even higher to Pollux and Castor with bright Jupiter below them, then from Castor farther lower right to Menkalinen and Capella, then lower left to Aldebaran, then duck lower left around to Rigel at the bottom of Orion, and back to Sirius. Within the Hexagon shine Jupiter and Betelgeuse.
