星系

On the basis of symmetry model of cosmos of material and antimatter energy with the center of star of antimatter and material of extra negative energy,this paper analyzed proton and antiproton of negative energy,which have not agglomerated to the star of antimatter and material of extra negative energy,and it puts forward that the space so called"empty with nothing"can produce young galaxy.

以特大负能反正物质星体为中心的正能正反物质对称宇宙模型的基础上，对尚未凝聚到特大负能反正物质星体中去的负能反正质子和所谓空无一物的空间区能产生年轻的星系作了进一步分析，从而发展成了正负能正反物质对称宇宙模型，使得更多的天文观测资料都能做出统一的解释

All the stars, galaxies and gas observable in the universe account for less than a half of all the baryons that should be around.

宇宙中所有观测到的恒星、星系和气体总和还不到应该存在的重子的一半。

They still haven't found any Martian microbes, or telltale signs of alien biospheres orbiting distant stars.

他们仍然没有发现火星微生物，或者是远方星系外来生物的迹象。

He suggested the following figures should be multiplied: how many stars are formed in the galaxy in a year; what fraction of these have planets and thus form solar systems; the average number of planets per solar system that have the potential to support life; on what percentage of those where it is possible do such biospheres actually form; what percentage of such biospheres give rise to intelligent species; what percentage of intelligent life is able to transmit signals into space; and for how long could such intelligence keeps sending signals.

他的方法包括一系列应该纳入考虑范围的数据：银河系每年新诞生的恒星数；拥有行星并组成了星系的恒星比率；有可能会出现生命迹象的行星平均数；以上行星能够真正孕育生命的比率；演化出了智能物种的比率；能使用无线电通讯与外太空联系的智能生物比率；智能生物使用无线电通讯方式的持续时间。更多信息请访问： http：//www.24en.com

Do you have great ambitions for the multiplayer mode galaxy wars like boneyards?

对于多人游戏部分你们有什么大计划像是boneyard那样的星系战争？

Dr. Brinks in Mexico once showed a photograph of a small galaxy called HO2 that had been blown almost to bits by starbursts.

墨西哥的布林克思博士曾出示过一张照片，该照片表明，一个叫H02的小星系就是被星云风暴吹成了碎片。

To reduce the uncertainty in virgo's distance, freedman and her colleagues will search for cepheids in two other galaxies in virgo.

为减少室女星团距离计算上的不确定因素，弗里德曼及其同事准备在室女星团的另两个星系内寻找造父变星。

By observing Cepheids with very similar properties at near-infrared wavelengths in all seven galaxies, and using the same telescope and instrument, the team was able to more precisely calibrate the luminosity of supernovae.

通过很相似的方法，在全部7个星系中用相同的望远镜和仪器，在近红外波段观测造父变星和超新星，团队能够更加精确地校准Ia超新星的光度。

Because NGC 4603 is much farther away than the other galaxies studied with Hubble by the Key Project team, 108 million light-years, its stars appear very faint from the Earth, and so accurately measuring their brightness, as is required for distinguishing the characteristic variations of Cepheids, is extremely difficult.

由于它远在1.08亿光年外，远超项目组团队研究的其他星系，故此恒星变得非常黯淡，而任务要求必须正确测定其中的特定变星——造父变星——的光度，显得格外困难。

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。
