Rare celestial event: Moon hides the star Regulus tonight
罕見天文現象：今晚月掩軒轅十四
Tonight, astronomy enthusiasts have the chance to witness a rare and fascinating celestial event: a lunar occultation of the star Regulus.
今晚，天文愛好者有機會目睹一場罕見且迷人的天文現象：獅子座α星（軒轅十四）的月掩星現象。
This occurs when the Moon passes directly in front of the bright star, temporarily hiding it from view.
當月球直接運行到這顆明亮恆星的前方，並暫時將其遮擋時，此現象便會發生。
Unlike sunsets, where light fades slowly, the lack of a lunar atmosphere causes Regulus to vanish instantly, like a light switch being turned off.
與日落時光線緩慢消逝不同，由於月球缺乏大氣層，軒轅十四會像電燈開關被關掉一樣瞬間消失。
Regulus, the 'Heart of the Lion' in the constellation Leo, is a massive blue-white star located 79 light-years away.
軒轅十四被稱為獅子座的「獅子之心」，是一顆位於79光年外的巨大藍白色恆星。
Because the Moon is relatively close to Earth, this event is highly location-specific.
因為月球距離地球相對較近，所以此現象具有極高的地域性。
For the best experience, experts recommend using binoculars or a small telescope to watch the star disappear behind the Moon’s dark leading edge and reappear at the bright trailing edge.
為了獲得最佳觀測體驗，專家建議使用雙筒望遠鏡或小型天文望遠鏡，觀察該恆星消失在月球陰暗的前緣後，並再度出現在明亮的後緣。
If you are positioned at the very edge of the visibility path, you might even witness a 'flickering' effect caused by the Moon's rugged craters.
如果你剛好位於可視範圍的邊緣，甚至還能目睹由於月球凹凸不平的環形山所引發的「閃爍」效應。
Check local astronomical resources to see if this spectacular 'star and crescent' pairing is visible from your region tonight.
請查詢當地的天文資訊，看今晚你的地區是否能看到這場壯觀的「星月伴隨」景象。
