The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. A tremendously bright nearby star, Herschel 36, lights the area. Vast walls of dust hide and redden other hot young stars. As energy from these stars pours into the cool dust and gas, large temperature differences in adjoining regions can be created generating shearing winds which may cause the funnels. This picture, spanning about 10 light years, combines images taken in six colors by the orbiting Hubble Space Telescope. The Lagoon Nebula, also known as M8, lies about 5000 light years distant toward the constellation of the Archer (Sagittarius). 

泻湖星云的中心是一个壮观的恒星形成旋风。在图像中心附近可以看到，至少有两个漏斗状的长云，每个大约半光年长，是由极端的恒星风和强烈的高能星光形成的。附近一颗非常明亮的恒星赫歇尔36号照亮了这一地区。巨大的尘埃墙掩盖了其他炽热的年轻恒星并使其变红。当这些恒星的能量注入冷尘埃和气体时，相邻区域会产生巨大的温差，产生切变风，可能导致漏斗。这张照片跨度约10光年，结合了哈勃太空望远镜在轨道上拍摄的六种颜色的图像。泻湖星云也被称为M8，距离射手座约5000光年。
