The majestic Lagoon Nebula is filled with hot gas and the home for many young stars. Spanning 100 light years across while lying only about 5000 light years distant, the Lagoon Nebula is so big and bright that it can be seen without a telescope toward the constellation of the Archer (Sagittarius). Many bright stars are visible from NGC 6530, an open cluster that formed in the nebula only several million years ago. The greater nebula, also known as M8 and NGC 6523, is named “Lagoon” for the band of dust seen to the right of the open cluster’s center. The featured image was taken in the light emitted by Hydrogen (shown in brown), Sulfur (red), and Oxygen (blue) and displayed in enhanced color. The featured picture is a newly processed panorama of M8, capturing twice the diameter of the Full Moon. Star formation continues in the Lagoon Nebula as witnessed by the many globules that exist there. AAS Conventioneers: APOD Town Meeting Wednesday at 2:15 pm

🌌 雄偉的Lagoon Nebula充滿了熱氣體，是許多年輕恆星的家園。它橫跨100光年，距離我們僅有約5000光年之遠。Lagoon Nebula如此巨大明亮，以至於在射手座(Sagittarius)這個星座中，肉眼即可看到。從開放星團NGC 6530可見許多明亮的恆星，這個星團在幾百萬年前於星雲中形成。這個大星雲也被稱為M8和NGC 6523，因為星團中心右側的一條塵埃帶而名為「Lagoon」。這張照片是以氫（顯示為棕色）、硫（紅色）和氧（藍色）發出的光線拍攝，加上增強的顏色呈現。這張亮點圖片是M8的全新處理全景，捕捉了兩倍於滿月直徑的景象。在Lagoon Nebula中，恒星的形成仍在繼續，這可以從當中存在的許多小雲團看出。
