星云

The light of our galaxy is emitted from, at least, 200 billion stars converged at the existing star formation and from a great volume of stars and star clouds. It is a tremendous galaxy of whirlpool type with the confluence of a variety of interstellar materials, whose diameter is more than 7,000 light-years.

银河系是由我们所在的星系中至少2000亿颗星体和星云中的许多星体和星云所发出的光，以及各类星际物质等汇合而成的直径超过7000光年的巨型旋涡状星系。

Explanation: Appropriately nicknamed "the Skull Nebula", planetary nebula NGC 246 really does surround a dying star some 1,600 light-years away in the constellation Cetus.

解释："骷髅星云"，形容行星状星云NGC 246的一个很合适的绰号，围绕着大约1600光年之外的鲸鱼座座的一颗正在死亡的恒星。

Appropriately nicknamed "the Skull Nebula", planetary nebula NGC 246 really does surround a dying star some 1,600 light-years away in the constellation Cetus.

位在鲸鱼座离我们约1，600光年远的行星状星云NGC 246，有个骷髅星云的贴切昵称，因为它中心的确有一颗滨临死亡的恒星。

Looking skyward along the Milky Way's arc from the left are Alpha and Beta Centauri, the Coalsack, the Southern Cross, and the Carina Nebula.

朝天空看，循着银河的亮弧，从左边半人马α和β，至煤袋星云，南十字，船底星云。

The left over cosmic debris is steadily being consumed by a black hole with a billion times the mass of the Sun which lies at the center of Centaurus A.

这个行星状星云被认为是一颗类似太阳的恒星正处于生命的最后阶段。最近，许多行星状星云被发现也具有这样的光晕，可能是在恒星演变早期由内部抛出的物质形成。

The Crab Nebula -- The Crab Nebula, the result of a supernova noted by Earth-bound chroniclers in 1054 AD, is filled with mysterious filaments that are are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion.

蟹状星云-蟹状星云，在公元1054结果在地球方向的编年史家所指出的超新星，是充斥着神秘的细丝，不仅极其复杂，但似乎少质量比并驱逐了原超新星从一个更高的速度比预期的自由爆炸。

Officially designated NGC 3324, the Keyhole Nebula is a smaller region superposed on the larger Eta Carina Nebula.

他正式的编号为NGC3324。钥匙洞星云是叠在较大的Eta Carina星云上的小星云。

Of the two reflection nebulas pictured above, the more famous nebula is M78, on the upper right, while NGC 2071 can be seen to its lower left.

上面影像中两个反射星云相比，较著名的是位于影像右上角的M78星云，而在它的左下方的则是NGC2071星云。

Visible above are red glowing emission nebulas of hydrogen, blue reflection nebulas of dust, dark absorption nebulas of dust, and the stars that formed from them.

上图所见，红色的部份是高温由氢组成的发射星云、蓝色的部份是尘埃造成的反射星云、而黑色的部份是尘埃所产生的吸收星云，恒星便是从中诞生。

Just below the Southern Cross on the far left is the dark Coal Sack Nebula, and the bright nebula on the far right is the Carina Nebula.

南十字座左下方的是黑暗的煤袋星云，而最右侧明亮的星云是船底座星云。

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%.
