在遙遠的宇宙中，Kappa Cygnid流星雨像小星星一樣閃爍著！這個流星雨的名字來自於它的發源地，指向一顆叫做Kappa Cygni的星星。每年八月中旬，這個流星雨會達到最亮的時刻，但是它的流星數量不如其他更有名的流星雨，例如Perseid流星雨。雖然Kappa Cygnid的流星每小時只有大約3顆，但在許多天文愛好者的努力下，從2012年到2024年的51個八月夜裡，已經能拍到許多美麗的流星照片！特別是在2021年，這個流星雨達到了它的活躍高峰，因為那一年特別多流星出現。拍攝這些奇妙的流星時，還記錄了美麗的銀河，呈現在希臘的Elafonisi海灘上，讓人久久不能忘懷！

Meteors from the Kappa Cygnid meteor shower are captured in this time-lapse composite skyscape. The minor meteor shower, with a radiant not far from its eponymous star Kappa Cygni, peaks in mid-August, almost at the same time as the much better-known and better-observed Perseid meteor shower. But, seen to have a peak rate of only about 3 meteors per hour, Kappa Cygnids are vastly outnumbered by the more popular, prolific Perseid shower’s meteors that emanate from the heroic constellation Perseus. To capture dozens of Kappa Cygnids, this long term astro-imaging project compiled meteors in exposures selected from over 51 August nights during the years 2012 through 2024. Most of the exposures with identified Kappa Cygnid meteors were made in August 2021, a high point of the shower’s known 7-year activity cycle. All twelve years worth of Kappa Cygnids are registered against a base sea and night skyscape of the Milky Way above Elafonisi Beach, Crete, Greece, also recorded in August of 2021.
