當這顆已經很亮的彗星靠近時會發生什麼？ 樂觀的預測認為，彗星C/ 2023 A 3 （Tsuchinshan-ATLAS）會在短時間內變得容易被肉眼看到--儘管彗星未來的亮度很難預測，這顆彗星甚至可能在溫暖的陽光下碎裂。但可以肯定的是，這顆彗星現在出乎意料地明亮，並有望在本週晚些時候透過離太陽最近的位置（ 0 . 39 AU），在下月初透過離地球最近的位置（ 0 . 47 AU）。 這張圖片拍攝於 5 月底，當時去年才發現的月琴山-ATLAS 彗星幾乎從兩個遙遠星系的前方穿過。 現在可以用雙筒望遠鏡在清晨的天空中發現這顆彗星，它就在太陽之前升起，而在接下來的幾周裡，當它移到傍晚的天空時會變得更加明亮。 您的天空驚喜你的生日是哪一天？
原文：What will happen as this already bright comet approaches? Optimistic predictions have Comet C/2023 A3 (Tsuchinshan–ATLAS) briefly becoming easily visible to the unaided eye -- although the future brightness of comets are notoriously hard to predict, and this comet may even break up in warming sunlight. What is certain is that the comet is now unexpectedly bright and is on track to pass its closest to the Sun (0.39 AU) later this week and closest to the Earth (0.47 AU) early next month. The featured image was taken in late May as Comet Tsuchinshan–ATLAS, discovered only last year, passed nearly in front of two distant galaxies. The comet can now be found with binoculars in the early morning sky rising just before the Sun, while over the next few weeks it will brighten as it moves to the early evening sky.
