星云

An emission nebula that contains much dust, the Keyhole Nebula is roughly 9,000 light years distant.

钥匙洞星云是一个包含有大量星际尘埃的辐射星云，距离地球大约9000光年。

The top of the Keyhole Nebula, the mostprominent feature embedded inside Carina, is on the left.

深植在船底座星云内部最显著的特征&锁眼&星云的顶端位于图像左侧。

The Keyhole Nebula, visible left the center , houses several of the most massive stars known and has also changed its appearance.

图像中心左边是锁眼星云，拥有几个已知的最巨大的恒星，也在一直改变着星云外观。

The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel.

此图片是张大的近乎圆形的特写，是钥匙洞星云的一部分。钥匙洞星云这个名字是十九世纪John Herschel命名。

Previously unseen details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the 'Keyhole Nebula,' obtained with the Hubble Space Telescope.

哈 勃空间望远镜使我们通过这张钥匙洞星云的图片看见前所未见的细节--神秘的船底座星云（NGC 3372）的复杂结构。

Covering an area surrounding the dusty Keyhole Nebula (NGC 3324) near picture center, the image spans about 40 light-years within the larger Carina Nebula at an estimated distance of 7,500 light-years, Like the more northerly Orion Nebula, the bright Carina Nebula is easily visible to the naked-eye.

船底座星云的推算距离为是7，500光年，所以这幅影像呈现了船底座星云约四十光年的区域。

At the nebula's centre, a clutch of massive,scorching stars send waves of matter smashing into the surrounding interstellar material, generating a glowing structure that appears ring-like from our perspective.

图中左上方就有这样令人瞩目的水泡状星云，在星云中央，一群炽热巨星的恒星风高速冲入周围的星际物质中，从我们远方看来，就激起环形的发光结构。

Asteroids, comets and meteoroids are all debris remaining from the nebula in which the Solar System formed 4.6 billion years ago.

小行星、彗星和流星体全部都是来自星云的残存的碎片，46 亿年前太阳系在这个星云中形成。

Numerous red emission nebulas and blue reflection nebulas are visible throughout the image.

无数红热喷射星云和蓝色反射星云也在此图中清晰可见。

Astronomers have argued for years about how stars condense out of the diffuse clouds of dust and gas called nebulas.

由尘埃和气体构成的云团被称为星云。有关恒星如何从呈弥漫状态的星云凝缩而来，天文学家们争论了很多年。

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％。
