查询词典 nebulas

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。

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。

Using existing observations, the researchers analyzed the polarized light emissions from 25 dense areas within several nebulas that are up to 6500 light-years from Earth.

研究人员利用现有的观测资料，对距地球6500光年以外的几团星云内部中25个高密度区域所释放的偏振光进行了分析。

Using data collected from previous sky surveys, the researchers analyzed the polarized light emissions from 25 dense areas within several molecular clouds, or nebulas, which are up to 6500 light-years from Earth.

使用从以前的天空调查所收集的数据，研究人员分析了来自25多个密集地区分子云内，或星云，这是高达6500光年的距离地球年偏振光排放。

Though Bob Fera just calls this a test image, I think he has done a nice job with the North American and Pelican Nebulas.

尽管Bob Fera只把这个成为一张&测试片&，我想他已经把北美星云和塘鹅星云拍得非常好了。

Planetary nebulas - so called because some of them resemble a planet when viewed through a small telescope - are produced in the late stages of a sun-like star's life.

行星状星云得名的原因是外观在小望远镜中类似行星，是类太阳恒星在演化后期产生的。

Mass Effect 2 takes the bleak vacuum of space and flushes it with color--the light of stars and galaxies, the red and violet swirls of far-off nebulas, and the glimpses of comets as they burn through the void.

质量效应2采用暗淡的空间，并刷新真空彩色它-遥远星云的恒星和星系，红色和紫色的旋涡光，以及彗星的一瞥，他们通过无效烧伤。

But Orion's stars and nebulas don't look quite as colorful to the eye as they do in this lovely camera image, taken early last month at the Black Forest Star Party from Cherry Springs State Park in Pennsylvania, USA.

但是，猎户座中的恒星和星云肉眼看上去并不像这张可爱的照片中那样多彩。这张照片是上个月在美国宾夕法尼亚的欢乐泉州立公园的黑森林星空营地上拍摄的。

This high speed wind appears to be concentrated into opposing supersonic funnels, and produces the elongated shapes in the early development of planetary nebulas BD+30-3639 appears spherical, but other observations indicate that it is viewed along the pole.

高速风似乎集中于对面的超音速漏斗状结构中，并在行星状星云演化的早期造就了拉伸的外观。（BD+30-3639看起来呈球形，但其他观测表明，我们是在从极区观看它。

According to NASA, Hubble's keen 'eye' disclosed that planetary nebulas are like snowflakes: no two are like.

哈勃望远镜告诉人们，行星状星云就像雪花一样，没有任何两个是一样的。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.
