nebula

Infrared observations indicate that this nebula may contain complex carbon molecules known as PAHs.

红外观测器还发现这个星云可能含有叫作多环芳烃的复杂碳分子。

Previously, almost all solar systems seemed to be engulfed by a nebula and there was very little black in the sky around you.

以前，差不多所有恒星系都在星云之中，只有少量星空是黑暗的。

Most scientists believe that the solar system formed from a Nebula of gas, dust and ices, that turned into a disk around the developing sun.

大部分科学家认为太阳系是由包含气体、星尘和冰的星云构成，它们像圆盘一样围绕在膨胀的太阳周围。

Few astronomical sights excite the imagination like the nearby stellar nursery known as the Orion Nebula.

很少有天文景观能像这个邻近的星星育婴房-著名的猎户座星云-激发著人类的想像力。

The name stuck even though the opposite turned out to be true: this type of nebula consists of gas molted from dying stars.

这个名字从此流传下来，即使事实真相刚好相反：这类星云是由濒死恒星所崩落的气体构成的。

Explanation: One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud.

解说：这是天空中最易辨认的星云之一。猎户中的马头星云是一个巨大的黑暗分子云的一部分。

Pictured above is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy.

上图为鹰状星云若干突出的尘埃柱之一，就像是一个巨大的外星精灵。

The dark shape was once assumed to be an obscuring dust cloud seen in silhouette against the bright reflection nebula.

在过去，这个暗色天体曾被认为是个尘埃星云，因为遮掩了后方明亮反射星云的光，而以剪影的形式现踪。

It is one of the best examples of a planetary nebula and a favorite target of amateur astronomers.

它是行星状星云的最好范例之一，也是业余天文爱好者最喜欢观测的目标之一。

l Nebula (plural nebulae) was the word once used for and fuzzy patch of light in the night sky.

l星云这个名称，过去曾经用来泛指夜空中那些发亮的小块区域。

The general shape of the average nebula is that of a thin circular disk somewhat thick in the center.

星云最常见的形状是中间较厚边缘较薄的圆盘。

In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town.

在星云的正中心有一个脉冲星：一个中心星，它拥有和太阳类似的质量而只有一个小村庄那么大。

It is within this sort of psychic nebula that the sense of core weight and flowering lightness originate.

核心重量跟开花的轻盈，就开始于这种心理的朦胧星云的范围内。

So most people, you know, kind of have no idea of the difference between like, an emission nebula and a planetary nebula.

这和实际的频率和规模几乎是一样的。大多数人都分不清发射星云和环状星云之间的区别。

A bit of mould is a pleiad of flowers; a nebula is an ant-hill of stars.

一粒霉菌是一簇美不胜收的花朵，一撮星云是无数天体的蚁聚。

About 5 light-years long and a mere 800 light-years away, the Pencil Nebula is only a small part of the Vela supernova remnant.

约5光年长，仅800光年远，铅笔星云是船帆座超新星残骸的一小部分。

In the nebula's very center lies a pulsar: aneutron star as massive as the Sun but with only the size of a smalltown.

在星云的正中心有一个脉冲星：一个中子星，它拥有和太阳类似的质量而只有一个小村庄那么大。

Like brush strokes on a canvas, ridges of color seem to flow across the Lagoon Nebula, a canvas nearly 3 light-years wide.

就如同画布上的笔触，浓重的色带流过泻湖星云，而这张画布几乎有3光年宽。

Were the Tarantula Nebula at the distance of the Orion Nebula -- a local star forming region -- it would take up fully half the sky.

假如狼蛛星云在猎户座星云——一个本地（银河系内）恒星形成区——的位置上，它将占据半个天空。

Messier 27 (M27) is an excellent example of a gaseous emission nebula created as a sun-like star runs out of nuclear fuel in its core.

Messier27（M27）是个气体发射星云的典型例子，它是由于类似太阳的恒星耗尽了其核心的核燃料而产生的。
