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]。

蟹狀星雲是位於金牛座ζ星東北面的一個超新星殘骸和脈衝風星雲，是銀河系英仙臂的一部分，距地球約6,500光年，直徑達11光年，並以每秒約1,500公里的速度膨脹。該星雲由約翰·貝維斯於1731年發現，對應中國、阿拉伯和日本天文學家於公元1054年記錄的一次超新星爆發。維基百科

M42 - M43

https://en.wikipedia.org/wiki/Orion_Nebula

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, ^[b] and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with apparent magnitude 4.0. It is 1,344 ± 20 light-years (412.1 ± 6.1 pc) away^[3]^[6] and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

獵戶座大星雲（M42，NGC 1976）是一個位於銀河系的瀰漫星雲，在天空中坐落在獵戶座的獵戶腰帶位置^[b]，作為獵戶之劍的中心。獵戶座大星雲是亮度最高的星雲之一，在夜空中裸眼可見，視星等為4.0。星雲距離地球1,344正負20光年（412.1正負6.1秒差距）^[4]^[5]，是最接近地球的一個恆星形成區。星雲寬度約24光年，因此從地球觀察其寬度約為1度。它的質量約為太陽的2,000倍。

長久以來，獵戶座大星雲都是夜空中倍受關注的拍攝對象，並且它也得到了天文學家們的廣泛研究。^[6]對此星雲的研究可揭示出恆星和行星系統的形成過程：星雲中的氣體和塵埃因引力坍縮，並最終演變為星體。近年天文學家已直接觀測到該星雲四合星附近的原行星盤、棕矮星、激烈的氣體湍流，以及附近大量出現的光電離恆星。

https://en.wikipedia.org/wiki/Pleiades

The Pleiades (/ˈpliː.ədiːz, ˈpleɪ-, ˈplaɪ-/),^[7]^[8] also known as The Seven Sisters, Messier 45 and other names by different cultures, is an asterism and an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. At a distance of about 444 light years, it is among the nearest star clusters to Earth. It is the nearest Messier object to Earth, and is the most obvious cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII region.

昴宿星團^[4]^[5]，簡稱昴星團，又稱七姊妹星團，梅西耶星雲星團表編號M45，是一個大而明亮的疏散星團，位於金牛座，裸眼就可以輕易看見，肉眼通常見到有九顆亮星。昴星團的視直徑約2°，形成斗狀。成員星數在200個以上，是一個很年輕的星團。昴星團也是一個移動星群。
