  5. The Night Sky Monday, April 2 · Venus is passing through the outskirts of the Pleiades this evening through Wednesday evening, as shown above. Binoculars or a wide-field telescope give a fine view of the delicate cluster behind Venus's overpowering glare. · The waxing gibbous Moon forms a slightly curving line with Mars and Regulus, as shown at right. Tuesday, April 3 · The Moon now forms the bottom point of a narrow triangle with Mars and Regulus, as shown at right. · Venus is the closest it will come to the middle of the Pleiades. This evening for the Americas, Venus is passing just ½° southeast of Alcyone (the brightest Pleiad) and ¼° south of the Atlas-Pleione pair. Venus is magnitude –4.5, which means Alcyone, at magnitude 2.85, is 900 times fainter! Wednesday, April 4 · Two planet-and-star pairings mark the evening sky of spring 2012. After nightfall this week, Mars shines high in the south with Regulus to its right (by 5°). As evening advances, Saturn rises into view low in the east-southeast with Spica to its right (by 5½°). Thursday, April 5 · The Moon is nearly full this evening. Look left of it for Gamma (ã) Virginis (Porrima), a tight telescopic double star. (Its separation is 1.8 arcseconds this spring; it's widening year by year). Look farther lower left of the Moon for steady-shining Saturn and twinkly Spica, as shown here. And look to the Moon's lower right for the four-star pattern of the constellation Corvus, the Crow. Friday, April 6 · Full Moon (exact at 3:19 p.m. EDT). This evening the Moon shines in the east with Spica a little to its left and Saturn farther left — a pretty lineup, as shown here. Farther to the Moon's right, look for the four-star pattern of Corvus, the Crow. Much farther to the upper left (outside the picture here) is bright Arcturus, the "Spring Star."
