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，你可以看到大量發(fā)光的氣體云銀河系。有些用肉眼可見，有些用雙筒望遠鏡觀察到，還有大多數(shù)需要一個望遠鏡和一個月亮更少的晚上的能見度。其中最著名的星云是獵戶座星云，作為宇宙向我們展示的一個研究。

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.

星云也許很難理解。燃燒的氣體云正在坍縮成新生的恒星，老化的太陽的死亡覆蓋物，或者僅僅是不間斷的宇宙循環(huán)進程中的碎屑，這些氣體云在星系的運行方式中發(fā)揮著重要作用。它們很難測量；它們的距離嚴重地阻止了我的測量，除非明亮的恒星碰巧能隨意地落在它們里面。天文學家知道獵戶座星云大約需要1500光年，但這是一個估計。獵戶座的整個區(qū)域都被所謂的獵戶座淹沒了分子云，一個橫跨幾百光年的巨大氣泡。

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.?

我們看到了這個建筑群中最亮的部分，包括獵戶座星云和星云的圓形和背光結(jié)構(gòu)是著名的暗星云馬頭，因為明亮的恒星激活了云中的那些部分。但是，大量的氣體，以及構(gòu)成黑色星云的塵埃，大多沒有被注意到。這個區(qū)域提醒我們，我們在天空中看到的東西只是冰山一角。在安靜的黑暗中，我們還無法從太空中梳理出來。
