The famous Horsehead Nebula in Orion is notalone. A deep exposure shows that the dark familiar shaped indentation, visiblejust below center, is part of a vast complex of absorbing dust and glowing gas.To bring out details of the Horsehead's pasture, an amateur astronomer used abackyard telescope in Austria to accumulate and artistically combine 7.5 hoursof images in the light of Hydrogen (red), Oxygen (green), and Sulfur (blue).The resulting spectacular picture details an intricate tapestry of gaseouswisps and dust-laden filaments that were created and sculpted over eons bystellar winds and ancient supernovas. The Flame Nebula is visible just to theleft of the Horsehead, while the bright star on the upper left is Alnilam, thecentral star in Orion's Belt. The Horsehead Nebula lies 1,500 light yearsdistant towards the constellation of Orion.
马头星云四周的云气丝
猎户座中著名的马头星云并不孤单。它呈现在这幅深空曝光照片的中心下方，显示为黑暗斑块，它是一个由尘埃和炽热气体组成的巨大复杂体的一部分。为了呈现出马头星云的细致结构，一位位于奥地利的天文爱好者在家中后院使用望远镜对其进行时长7.5个小时的拍摄，艺术性地合成了这幅照片，其中氢、氧和硫分别发出红色、绿色和蓝色辉光。这幅壮观的合成照片详细描绘了一幅由气态云气丝和丝状尘埃构成的复杂织锦，它们都是长久以来被恒星风和古代超新星所侵蚀而成的。火焰星云就在马头星云的左侧，而照片左上方的亮星则是猎户座腰带上的中央恒星——参宿二。马头星云位于猎户座，距离我们1,500光年远。
