桌面酷图系列——桌面19——M78的星星形成区域（适合用于夜间观测的电脑）
http://antwrp.gsfc.nasa.gov/apod/image/0511/M78_messner_f.jpg说明: 这是一张显示猎户座中央星际物质以及亮星云的照片。其中之一的
M78正好就在照片的中下方，也就是猎户腰带的北方。这个星云距离我们大约
1,500 光年，宽约5光年。影像中的淡蓝色是因为星际尘埃反射年轻星球所发出
的蓝光。这些星际尘埃还包括刚发现不久的麦克尼尔星云，一个可能与我们的太阳
系相类似的行星系统。

原文: Interstellar dust clouds and bright nebulae abound in the fertile constellation of Orion. One of the brightest, M78, is just below center in this sharp widefield view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish nebula itself is about 5 light-years across. Its blue tint is due to dust preferentially reflecting the blue light of hot, young stars in the region. Dark dust lanes and other nebulae can easily be traced through this gorgeous skyscape that also includes the remarkable McNeil's Nebula -- a newly recognized nebula associated with the formation of a sun-like star.
