Glowing clouds of gas
Go under a really dark sky, and you can see a vast array of glowing clouds of gas littering
the Milky Way Galaxy. Some are visible with the naked eye, others in binoculars, and most require a telescope and a moonless night for visibility. The most famous nebula of all, the Orion Nebula, stands as a case study in what the cosmos shows us.
在非常黑暗的天空下,你可以看到大量发光的气体云银河系。有些用肉眼可见,有些用双筒望远镜观察到,还有大多数需要一个望远镜和一个月亮更少的晚上的能见度。其中最著名的星云是猎户座星云,作为宇宙向我们展示的一个研究。
Nebulae can be nebulous to understand. Glowing clouds of gas that are collapsing into newborn stars, the death shrouds of aged suns, or simply the detritus in the ongoing cosmic recycling program, these clouds of gas play a major role in how galaxies work. They are difficult to gauge; their distances are hard to determine, unless bright stars happen to be lodged conveniently within them. Astronomers know the Orion Nebula is about 1,500 light-years away, but that’s an estimate. The whole region of the constellation Orion is swamped in what’s known as the Orion Molecular Cloud, a vast bubble stretching several hundred light years across.
星云也许很难理解。燃烧的气体云正在坍缩成新生的恒星,老化的太阳的死亡覆盖物,或者仅仅是不间断的宇宙循环进程中的碎屑,这些气体云在星系的运行方式中发挥着重要作用。它们很难测量;它们的距离严重地阻止了我的测量,除非明亮的恒星碰巧能随意地落在它们里面。天文学家知道猎户座星云大约需要1500光年,但这是一个估计。猎户座的整个区域都被所谓的猎户座淹没了分子云,一个横跨几百光年的巨大气泡。
We see the brightest parts of this complex, including the Orion Nebula and the nebulosity surrounding and backlighting the famous dark nebula called the Horsehead, because
bright stars energize those parts of the cloud. But large amounts of gas, as well as the dust that makes up dark nebulae, mostly go unnoticed.This area serves to remind us that what we see in the sky is but the tip of an iceberg. So much more lies in the quiet darkness that we cannot yet tease out of space.
我们看到了这个建筑群中最亮的部分,包括猎户座星云和星云的圆形和背光结构是著名的暗星云马头,因为明亮的恒星激活了云中的那些部分。但是,大量的气体,以及构成黑色星云的尘埃,大多没有被注意到。这个区域提醒我们,我们在天空中看到的东西只是冰山一角。在安静的黑暗中,我们还无法从太空中梳理出来。
