英文原文:Explanation: Have you ever seen a fireball? In astronomy, a fireball is a very bright meteor -- one at least as bright as Venus and possibly brighter than even a full Moon . Fireball s are rare -- if you see one you are likely to remember it for your whole life. Physically, a fireball is a small rock that originated from an asteroid or comet that typically leaves a fading smoke trail of gas and dust as it shoots through the Earth's atmosphere . It is unlikely that any single large ground strike occurred -- much of the rock likely vaporized as it broke up into many small pieces. The featured picture was captured last week from a deadwood beach in Cape San Blas , Florida , USA . Piece it Back Together: Astronomy Puzzle of the Day 说明: 你看过火流星吗? 在天文学里,火流星[2]是指非常明亮的流星[3],其亮度至少与金星[4]相当,有时甚至胜过满月[5]。 火流星[6]十分罕见,如果你有幸亲眼目睹,可能会终生难忘[7]。 以其物理本质来说,火流星[8]是小岩块,起源[9]于小行星[10]或彗星[11],通常在穿过地球大气[12]时,会留下逐渐消散的气体和尘埃流星迹[13]。 不过,它不太可能发生大型地面撞击,因为岩块在碎裂时会很快汽化。 这幅主题图像[14]是在上周摄于[15]美国[16] 佛罗里达[17]州圣布拉斯角[18]枯木散布的海滩。
