这个月，明亮的火星和灿烂的金星是日落后地球西部天空中突出的天体信标。6月3日晚，这颗红色行星在疏散星团梅西耶44附近被捕捉到，它正在蟹蟹座巨蟹座徘徊。这个附近的裸眼星团从古代起就被认为是Praesepe或Beehive星团。蜂巢星团是一群比太阳年轻得多的恒星，距离我们只有600光年。火星距离我们约17光分，呈黄色。6月12日至13日，金星将轮流在蜂巢星团的恒星旁边摆姿势。但金星耀眼的光芒将使蜂巢中的星星很难单凭肉眼看到。

This month, bright Mars and brilliant Venus are the prominent celestial beacons in planet Earth's western skies after sunset. Wandering through the constellation Cancer the Crab, the Red Planet was captured here on the evening of June 3 near the stars of open cluster Messier 44. Recognized since antiquity this nearby, naked-eye star cluster is also known as the Praesepe or the Beehive cluster. A swarm of stars all much younger than the Sun, the Beehive cluster is a mere 600 light-years distant. Seen with a yellowish hue, Mars is about 17 light-minutes away. On June 12/13 Venus will take its turn posing next to the stars of the Beehive cluster. But the dazzling light of Venus will make the Beehive stars difficult to see by eye alone.
