对于北方的天文学家来说，随着春天的临近，12P/庞斯-布鲁克斯彗星变得越来越亮。目前可以用小型望远镜和双筒望远镜看到这颗哈雷彗星，在未来几周内可以用肉眼看到。3月5日，在斯洛伐克雷乌卡拍摄的这张构图良好的深夜景中，尽管有雾笼罩，但这颗彗星的绿色彗发和长尾仍徘徊在地平线附近。M31，也被称为仙女座星系，和明亮的黄色恒星Mirach，仙女座的β星，悬挂在彗星上方的天空中。仙女座星系距离银河系约250万光年。庞斯-布鲁克斯彗星是太阳系内部的周期性访客，距离我们不到14光分。这颗彗星将于4月21日到达近日点，在4月8日的日全食期间，人们应该可以在天空中看到它。

As spring approaches for northern skygazers, Comet 12P/Pons-Brooks is growing brighter. Currently visible with small telescopes and binoculars, the Halley-type comet could reach naked eye visibility in the coming weeks. Seen despite a foggy atmosphere, the comet's green coma and long tail hover near the horizon in this well-composed deep night skyscape from Revuca, Slovakia recorded on March 5. M31, also known as the Andromeda galaxy, and bright yellowish star Mirach, beta star of the constellation Andromeda, hang in the sky above the comet. The Andromeda galaxy is some 2.5 million light-years beyond the Milky Way. Comet Pons-Brooks is a periodic visitor to the inner Solar System and less than 14 light-minutes away. Reaching its perihelion on April 21, this comet should be visible in the sky during the April 8 total solar eclipse.
