nebulae

Hubble said the light that appeared to come from nebulae really came from stars near the nebulae.

哈勃说，那些看似来自星云的光实际上是由星云附近的星发出的。

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。

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。

One of the most notable of these dark absorption nebulae is a cloud toward the constellation Ophiuchus known as Barnard 68, pictured above.

这类暗吸收星云里最著名的一个就是蛇夫座的巴纳德68，如上图所示。

The element hydrogen comprises 90% of the matter in gaseous nebulae.

元素氢占气体星云物质的百分之九十。

An image released by NASA shows the Heart and Soul nebulae in an infrared mosaic from the Wide-field Infrared Survey Explorer, or WISE.

美国宇航局发表的这个图像显示了广视野红外勘测探测器WISE拍摄的心与灵星云（HeartandSoul）红外马赛克。

The nebulae, he said, were clouds of atoms and dust. They were not hot enough -- like stars-- to give off light.

他说，星云是由原子和尘埃形成的云。他们不像星星那么热，不能发光。

Explanation: Bright nebulae abound in and around the expansive southern constellation of Centaurus .

说明：明亮的星云围绕在广阔的南方人马座周围。

The name originates from the 18th century, when telescopes weren't powerful enough to distinguish nebulae from gas giant planets.

这个名字源于18世纪，当时望远镜威力还不够强大，无法区分星云和气态巨行星。

This Hubble Space Telescope image reveals "The Cat's Eye Nebula" to be one of the most complex "planetary nebulae" known.

哈勃望远镜拍到的这张“猫眼状星云”是当前所知最复杂的“行星星云”之一。

The dim, dusty nebulae reflect starlight from our own Milky Way Galaxy and lie only a few hundred light-years above the galactic plane.

这些反射银河系盘面星光的黯淡尘埃云气，约在盘面上方数百光年的位置。

And he made an important discovery about nebulae.

关于星云，他做出了重大发现。

Switch your view to see the sky above your Earth location, and explore far-away galaxies, nebulae, and more.

转换您的视野，看看「地球」位置上的天空，探索遥远的银河、星群和其他。

Such tumultuous , often visually spectacular, interstellar regions surrounding youthful stars are known as gaseous nebulae.

这种环绕着年轻星的动荡且常常是壮观的星际区域，叫做气体星云。

Where the otherwise obscuring dust clouds lie close to the hot, young stars they also reflect starlight, forming blue reflection nebulae.

那些靠近年轻热恒星的遮蔽尘埃云也反射恒星光，形成蓝色的反射星云。

Supernovae may be flashier , but their debris is roiling and chaotic, lacking the symmetry and intricacy of these nebulae.

超新星或许较为明亮耀眼，但其残骸翻腾无序，欠缺如同行星状星云般的对称与复杂。

Light is unable to escape through a number of dark nebulae which are present there.

光线是无法逃出那里存在的大量暗色星云的。

This image from the Hubble Space Telescope reveals the Cat&squots Eye Nebula to be one of the most complex planetary nebulae known.

这张来自哈伯太空望远镜的影像，透露出猫眼星云是现知结构最复杂的行星状星云之一。

Its opponent on the right is composed of the faint stars, dust clouds, and nebulae along the plane of our Milky Way Galaxy.

而在对于面右侧是由昏暗恒星，尘埃云和星云组成的星河系盘面。

Hanging from his belt, the stars and nebulae of the Hunter's sword are visible lower and to the right.

我们可以看到代表猎人的腰带上吊着的宝剑的恒星和星云在右下方。
