星云

Officially known as NGC 2736, the Pencil Nebula is part of the huge Vela supernova

这个铅笔星云，官方名称是NGC 2736，是巨大的Vela超新星的残留物，她位于Vela星座的南部。

It also appears to solve the deuterium problem but only if the rocky materials out near the earth's present orbit picked up some local water from the solar nebula ( the cloud of gas and dust surrounding the young sun ) before they accreted to form the earth.

同时，看上去它也解决了气含量的问题——但是只有当外来的岩石物质处于地球现今轨道附近时，并且在它们增生形成地球之前，从太阳的星云里(围绕着年轻太阳的气体和尘埃)获取了水时，这个问题才最终得到解决。

In fact, the Carina Nebula is one of our galaxy's largest star-forming regions and home to young, extremely massive stars, including the still enigmatic variable Eta Carinae , a star with well over 100 times the mass of the Sun.

事实上，船底座星云也是银河系最大恒星诞生区域的一部分，也是年轻、极大质量恒星的家园，其中含有仍处于神秘变换中的船底座η星，其质量是太阳质量的100多倍。

Explanation: How did the star Eta Carinae create this unusual nebula?

说明：船底座η星是如何形成这个奇怪的星云？

Eta Carinae , the most energetic star in the nebula, was one of the brightest stars in the sky in the 1830s, but then faded dramatically.

船底座伊塔星是星云中最活跃的恒星，也是19世纪30年代天空中最明亮的一颗恒星，但后来戏剧性地消失了。

Glowing brightly in planet Earth's southern sky, the expansive Eta Carinae Nebula is a mere 10,000 light-years distant.

广阔的船底座η星云明亮地闪烁在地球南方天空中，它距离我们大约1万光年。

Cataloged as IC 2118, the Witch Head Nebula is about 1,000 light-years away.

编号IC2118的女巫头星云大约有1000光年远。

The more famous nebula is M78, near the image center, cataloged over 200 years ago.

二者中较著名的星云是位在影像中央的M78，早在二百多年前就被登录了，位在影像左上角的则是较不出名的NGC 2071。

The nebula, formally cataloged NGC 6543, is every bit as inscrutable as the J.R.R.

这个星云被正式命名为NGC 6543，它的每一点都像J.R.R。

For it the nebula cohered to an orb

为着它，星云凝结成一个地球

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
