星云

Caption:: The Crab Nebula is a six-light-year-wide expanding remnant of a star's supernova explosion.

公元1054年，中国天文史书上记录了一颗非常光亮的客星，我们现在知道这是一颗距离我们6500光年的恒星发生超新星爆炸产生的光芒，爆炸后的残骸现在成为了星云，这星云名为蟹状星云。

Above it to the left is the nebulosity around the belt star Zeta Orionis which contains the often photographed Horsehead Nebula (barely visible as a small indentation on the right side).

佩剑左上方是围绕在腰带恒星Zeta周围的暗星云，暗星云包括常被拍到的马头星云（在右侧勉强能见的小凹点）。

Explanation: At the center of this sharp skyscape, Centaurus A seems to be a fantastic jumble of old yellow stars, young blue star clusters, and imposing dark dust lanes.

说明：猫眼星云是（NGC6543）天空中最著名的行星状星云之一。这张令人印象深刻的广角影像的较亮中心区域中，我们能看到更为熟悉的星云外层轮廓。

This nebula is a bubble, and it's bubble because intense blasts of stellar wind and radiation for a nearby star have cut through the dust and hollowed out the middle.

N44F星云呈气泡状，之所以呈现这种奇特的形状，是因为剧烈的恒星风和附近恒星的辐射从尘埃中穿过，在中央位置留下了中空地带。N44F星云位于大麦哲伦星云内。

Explanation: The Horsehead Nebula is one of the most famous nebulae on the sky.

说明：马头星云是天空中最为著名的星云之一，它是这张影像中央左下方红色发射星云里的一块黑暗区域。

Like the Horsehead, the Flame, and the Orion Nebula itself, M78 is a readily visible part of the large Orion Molecular Cloud complex some 1,500 light-years distant.

像马头星云、火焰星云和猎户座星云本身一样， M78是猎户座分子云复合体中比较容易观测到的一部分，距离我们大约1，500光年。

In the center, the three prominent dust lanes that give the Trifid its name all come together.

在星云中央，三道巨大的尘埃暗带会聚在一起，使这个星云以三裂星云为名。

This material is compressed into a shell and further excites by the intense ultraviolent light emmitted from the new born star, resulting in the glowing bubble seen here.

这种星云是会自己发光的，举例，就如这个星云，看到的星云是於中间年幼的恒星所发出的气体与周围的气体相撞时发光。

Like other stellar nurseries, the Cocoon Nebula holds, at the same time, a bright red emission nebula, blue reflection nebulas, and dark absorption nebulas.

就像其它恒星孕育场一样，茧状星云同时具有明亮的红色发射星云，蓝色的反射星云以及黑暗的吸收星云的角色。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
