查询词典 galaxies

The VLA has been used to discover water on planet Mercury, radio-bright coronae around ordinary stars, micro-quasars in our Galaxy, gravitationally-induced Einstein rings around distant galaxies, and radio counterparts to cosmologically distant gamma-ray bursts.

科学家已藉由VLA发现水星上的水、正常恒星周围会辐射出明亮电波的日冕、银河系中的微类星体、遥远星系周围经重力作用产生的爱因斯坦环、以及遥远伽玛线爆发的电波同位对照影像。

To study the star formation properties of galaxies is one of the major tasks of extragalactic astronomy.

星系的恒星形成性质的研究是目前河外天体物理学的热门研究领域。

"The extragalactic background is very faint, and it is easily confused with the bright emission from the Milky Way," says Ackermann. With the background isolated in their studies (these background measurements are published in the 12 March edition of the journal Physical Review Letters ), Ajello and Ackermann then began to compare it with observations of relatively nearby active galaxies with black holes (called active galactic nuclei, or AGN).

系外伽玛射线背景是非常微弱的，而且很容易受到系内辐射源的干扰，（ Ackermann 等人对背景值的测量公布于3月12日的《物理评论快报》上）， Ajello 和 Ackermann 同时将这个测量结果与附近已被观测过的相对活跃的星系黑洞参数进行比较，这些参照对象有个专有名词，称为活动星系核， AGN 。

The findings indicate that the evolution of lenticular galaxies might not yet be complete.

研究发现，这个透镜星系的演化可能尚未完成。

Eric Linder of the University of California, Berkeley, who was not involved with the work, agrees that the map backs up the favoured theory that dark matter forms a scaffold on which galaxies form.

加州大学伯克利分校的 Eric Linder 虽未参与此项工作，但同样认为此图是对流行的理论：暗物质为星系的形成搭了架子的支持。

Large Magellanic Cloud, the Milky Way's satellite galaxies.

大麦哲伦云是银河系的卫星星系。

Located inside the Large Magellanic Cloud – one of our closest galaxies – in what some describe as a frightening sight, the Tarantula nebula is worth looking at in detail.

在离我们银河系最近的星系之一——大麦哲伦星系里，蜘蛛星云虽然有一个令人恐惧的名字，却很值得详细的研究。

The "Ghost of Mirach" galaxy as seen in the ultraviolet. Image credit: NASA/JPL-CaltechNASA's Galaxy Evolution Explorer has lifted the veil off a ghost known to haunt the local universe, providing new insight into the formation and evolution of galaxies.

美国航空航天局的银河演化探测器最近成功揭开了宇宙中&幽灵&星系的神秘面纱，天文望远镜首次观察到&幽灵星系&的真实面貌，这一发现为认识星系的形成和演化提供了新的依据。

The 2MASX J00482185-2507365 occulting pair is a pair of overlapping spiral galaxies found in the vicinity of NGC 253, the Sculptor Galaxy.

2MASX J00482185-2507365 重叠星系由两个螺旋形的星系重叠而成，与玉夫座星系（NGC 253 ）相邻。

Ordinary objects such as stars and galaxies tend to slow down an expanding universe and can even cause it to recollapse.

普通物体像是星球和星系等，倾向减缓宇宙膨胀的速度，甚至使得宇宙再次塌陷。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
