说明: 在礁湖星云里，恒星正和云气与尘埃进行争战，因此让摄影者得以拍到精彩的照片。亦名为M8的这团美丽星云，位在人马 座内，是一个不用借助双筒望远镜肉眼也可见的星云。恒星形成时的高能过程，除了造就了缤纷多彩的色泽，也造成各种紊乱的景观。例如，在上面这张影像左方，云气之所以发出辉光，是因为高能星光冲撞星际氢气及微量的硫和氧气所致。出现在M8各处的黝黑丝状尘埃，则是形成于低温巨星的大气或是超新星爆炸的碎片。我们现在看到来自M8的星光，远在5,000年前就出发了。光要越过影像中这片M8的区域，得用上50年。

Explanation: Stars are battling gas and dust in the Lagoon Nebulabut the photographers are winning.Also known as M8,this photogenic nebula is visibleeven without binoculars towards the constellation of the Archer (Sagittarius).The energetic processes ofstar formation create notonly the colors but the chaos.The glowing gas results from high-energy starlight striking interstellarhydrogen gas and trace amounts of sulfur, and oxygen gases.The darkdustfilaments that laceM8 were created inthe atmospheres of coolgiant stars and in thedebris fromsupernovae explosions.The light from M8 we see today left about5,000 years ago.Light takes about 50 years to cross this section ofM8.
