星星是成群結隊的。 天空中最有名的星群是昴宿星團,這是一個明亮的星團,用肉眼很容易就能看到。 昴宿星團距離我們只有大約 450 光年,形成於大約 1 億年前,很可能還會持續大約 2 . 5 億年。我們的太陽很可能誕生在一個星團中,但現在已經有大約 45 億年的歷史了,它誕生時的同伴早已散去。圖中的昴宿星團位於美國加利福尼亞州優勝美地國家公園著名的岩石建築半圓頂上方。這張特寫圖片是由 28 張前景曝光圖片和 174 張恆星背景圖片合成的,所有這些圖片都是在 2019 年 10 月的同一個晚上,由同一臺相機從同一地點拍攝的。在計算了昴宿星團和半穹星團未來並列的時間後,天文攝影師意外地收穫了一場停電,使得背景天空變得異常黑暗。 天體物理學家瀏覽天體物理學原始碼庫中的 3 , 500 多個程式碼
原文:Stars come in bunches. The most famous bunch of stars on the sky is the Pleiades, a bright cluster that can be easily seen with the unaided eye. The Pleiades lies only about 450 light years away, formed about 100 million years ago, and will likely last about another 250 million years. Our Sun was likely born in a star cluster, but now, being about 4.5 billion years old, its stellar birth companions have long since dispersed. The Pleiades star cluster is pictured over Half Dome, a famous rock structure in Yosemite National Park in California, USA. The featured image is a composite of 28 foreground exposures and 174 images of the stellar background, all taken from the same location and by the same camera on the same night in October 2019. After calculating the timing of a future juxtaposition of the Pleiades and Half Dome, the astrophotographer was unexpectedly rewarded by an electrical blackout, making the background sky unusually dark.
