隨著北方觀天者春天的到來, 12 P/Pons-Brooks 彗星越來越亮。目前,用小型望遠鏡和雙筒望遠鏡就能看到這顆哈雷型彗星,未來幾周內肉眼就能看到它。在 3 月 5 日從斯洛伐克 Revuca 拍攝的這幅構圖精巧的深夜天景圖中,儘管大氣中瀰漫著霧氣,但彗星的綠色彗尾和長尾仍在地平線附近盤旋。在哈雷型彗星上方的天空中,仙女座(右)和三角座星系在明亮的米拉奇星(仙女座的β星)兩側。這兩個螺旋星系是我們本星系群的成員,距離我們超過 250 萬光年。龐斯-布魯克斯彗星是太陽系內部的定期訪客,距離太陽系不到 14 光分。這顆彗星於 4 月 21 日到達近日點,在 4 月 8 日日全食期間應該可以在天空中看到。
原文: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. In the sky above the Halley-type comet, the Andromeda (right) and Triangulum galaxies flank bright star Mirach, beta star of the constellation Andromeda. The two spiral galaxies are members of our local galaxy group and over 2.5 million light-years distant. 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.
