5. The Night Sky Sky & Telescope Friday, May 9 The waxing gibbous Moon in the evening sky forms a curving line with Mars to its left, and Spica to the lower left of Mars. Saturday, May 10 Bright Mars shines left of the Moon. Although they look rather close together, Mars is 260 times farther away — and twice as big in diameter. Sunday, May 11 Now the Moon is positioned between Mars and Spica (for the Americas in the evening). Jupiter shines within the western Arch of Spring as twilight fades. The top of the Arch is formed by Pollux and Castor, roughly horizontal. To their lower left is Procyon, the left end of the Arch. The right end is formed by Menkalinen and then Capella. Jupiter is gradually moving toward the Arch's upper left side. Monday, May 12 Three zero-magnitude stars shine after dusk in May: Arcturus high in the southeast, Vega much lower in the northeast, and Capella in the northwest. They appear so bright because each is at least 60 times as luminous as the Sun, and they're all relatively nearby: 37, 25, and 42 light-years from us, respectively. Tuesday, May 13 The bright Moon, practically full, shines near Saturn. The Moon creeps to within 1° to 3° of Saturn before dawn Wednesday morning for the Americas. For New Zealand and most of Australia, the Moon occults (covers and uncovers) Saturn during nighttime; map and timetables.map and timetables
