在星空中，有一個美麗的星洲叫做Messier 6，或者叫做蝴蝶星團。這個星團有大約100顆星星，它們都年輕，大約100百萬年前形成。Messier 6 位於我們的銀河系中心，約有1,600光年遠，正好在天蠍座的方向上。這些星星在空中閃爍，像一隻展翅高飛的蝴蝶! 在星團中，還有一顆特別明亮的星星，叫做BM Scorpii，它散發著溫暖的黃色和橙色光芒，就像蝴蝶的觸角一樣。這幅宇宙的畫面看起來非常五彩斑斕，周圍的紅色氣體是由氫氣組成的，讓這個星團更加顯眼。你知道嗎? 整個Messier 6的大小大約是2個月亮的寬度呢，這在空中可是很大的一個範圍哦！
原文:
The sixth object in Charles Messier’s famous catalog of things which are not comets, Messier 6 is a galactic or open star cluster. A gathering of 100 stars or so, all around 100 million years young, M6 lies some 1,600 light-years away toward the central Milky Way in the constellation Scorpius. Also cataloged as NGC 6405, the pretty star cluster’s outline suggests its popular moniker, the Butterfly Cluster. Surrounded by diffuse reddish emission from the region’s hydrogen gas the cluster’s mostly hot and therefore blue stars are near the center of this colorful cosmic snapshot. But the brightest cluster member is a cool K-type giant star. Designated BM Scorpii it shines with a yellow-orange hue, seen near the end of one of the butterfly’s antennae. This telescopic field of view spans nearly 2 Full Moons on the sky. That’s 25 light-years at the estimated distance of Messier 6.
