星系

Sky with clouds in scattered clusters , or of cirro-cumulus type

在星系和球状星团之间没有任何不可逾越的鸿沟。

The two color - diagram is a useful tool to research the evolution of stars and AGNs.

双色图是一种研究恒星和活动星系核演化的有效工具。

Being given,an exact solution of the spatial distribution of interstellar gas is obtained,and the peak distribution of gas in disk-shaped galaxies is discussed.

分析了星系翼的一般特征，并具体地计算了银河系中星际气体的等密度曲线，提出了银河翼结构的一些可能趋势。

I control Mecatol Rex; I have a Space Dock here, and at least 4 Dreadnoughts in the Mecatol Rex

The greater nebula, also known as M8 and NGC 6523, is named "Lagoon" for the band of dust seen to the left of the open cluster's center.

更大的星云，像M8和已知的星系6523，名为&乐园&，可以看到的疏散星团的中心有尘埃带。

The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light.

可见光波段环绕在墨西哥帽星系腰部的黝黑尘埃带，在红外光波段却变得非常明亮。

The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light.

在普通光线下黑暗的尘埃带让草帽星系中间截面模糊不清，但在红外光线下能看到那里却发出明亮的光。

"Maybe what we're dealing with here is false memories, and not that people are actually being abducted and taken aboard spaceships," says Professor Chris French, who surveyed 19 self-proclaimed alien abductees.

但在最新公布的一项研究成果中，一位来自英国伦敦戈德史密斯学院的专家表示，这些所谓的奇特经历根本不能成为其它星系具有生命存在的有力证据，只能证明那些人的记忆系统出了某些问题而已。

Major advances have been made in the last a few years, including the discovery of fading X-ray, optical and radio afterglows of GRBs, the identification of host galaxies at cosmological distances, and evidence showing that many GRBs are associated with star-forming regions of the host galaxies and possibly a peculiar type of supernova.

过去几年里γ暴的研究取得了重大突破，包括发现了变暗的X射线、光学和射电余辉，探测到位于宇宙学距离的寄主星系，发现γ暴与恒星形成区成协、甚至可能与超新星关联的证据等等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
