M8 Lagoon Nebula ( 礁湖星雲 )
https://en.wikipedia.org/wiki/Lagoon_Nebula
The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region.
The Lagoon Nebula was discovered by Giovanni Hodierna before 1654[5] and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes. Seen with binoculars, it appears as a distinct cloud-like patch with a definite core. Within the nebula is the open cluster NGC 6530.

礁湖星雲（也稱為梅西耶8或M8、NGC 6523、沙普利斯25、RCW 146、和古姆72）是位於人馬座的一個巨大星際雲。它被歸類為發射星雲和氫離子區。
礁湖星雲是喬瓦尼·霍迪耶納在1654年之前發現的[4]，並且是北半球中緯度地區以肉眼隱約可以看見的兩個恆星形成區之一。用雙筒望遠鏡觀察，它看起來是一個明顯的橢圓形雲狀斑塊，並有明確的核心[5]。
