月亮探望姊妹星
Moon Visits Sister Stars

發表日期:2025-04-08
有時,月球會造訪昴宿星團。從技術上講,這意味著我們的月球軌道會把它帶到遠處著名的昴宿星團的正前方。 這一事件的專業術語是掩星,月球因罕見地掩星所有行星和幾顆著名的亮星而聞名。月球傾斜和前傾的軌道使得它對七姊妹星團的掩星現象非常頻繁,當前的掩星現象從 2023 年開始,每月一次,一直持續到 2029 年。不過,在此之後,下一次掩星要到 2042 年才會發生。 這張照片是 4 月 1 日從西班牙坎塔布里亞拍攝的,它是一張合成照片,在最後一張照片上,用數字技術添加了同一相機和同一地點之前曝光的昴宿星團照片,以呈現出星團標誌性的藍色光芒。 拼圖挑戰:每日天文拼圖
原文:Sometimes, the Moon visits the Pleiades. Technically, this means that the orbit of our Moon takes it directly in front of the famous Pleiades star cluster, which is far in the distance. The technical term for the event is an occultation, and the Moon is famous for its rare occultations of all planets and several well-known bright stars. The Moon's tilted and precessing orbit makes its occultations of the Seven Sisters star cluster bunchy, with the current epoch starting in 2023 continuing monthly until 2029. After that, though, the next occultation won't occur until 2042. Taken from Cantabria, Spain on April 1, the featured image is a composite where previous exposures of the Pleiades from the same camera and location were digitally added to the last image to bring up the star cluster's iconic blue glow.
