星系

AM 1316-241 is made up of two interacting galaxies - a spiral galaxy in front of an elliptical galaxy.

AM 1316-241由两个相互作用中的星系构成，一个漩涡星系处于一个椭圆星系前方。

Even though Barnard's Galaxy lacksthe majestic spiral arms and glowing, central bulge that grace its big galactic neighbours, the Milky Way, the Andromeda and the Triangulum galaxies, this dwarf galaxy has no shortage of stellar splendour and pyrotechnics.

尽管巴纳德星系缺少它的那些庞大邻居银河系、仙女座大星系(M31)和三角座星系（M33）等所具有的壮丽旋臂和璀璨的核球，它却不乏恒星焰火效果。

An astronomer can examinea galaxy and from its brightness make a guess as to how many stars and how much dusty gas it contains. Yet when we track the movements of galaxies in a self-contained cluster, they move as if galaxy were far heavier than it appear. It's like watching go-carts move as unstoppably as trucks.

尽管天文学家能够对某个星系进行观察并根据其亮度推测它所含恒星的数量和尘埃气体的多少，但是当我们把众多星系作为一个独立存在的整体来观察其运动时就会发现，每个星系运动起来似乎比我们所看到的要重得多，这就像我们看一辆儿童手推车以卡车般巨大、难以阻挡的惯性向前奔驰一样。

The first part is a summary of the late thirty years′observational materials, it divides the Active Galatic Nucleis into ordinary AGNs and Blazer, according to the radiation origin of thermal radiation or non-thermal radiation, and the view is strongly supported here.

论文的第一部分综述了活动星系核近三十年来的观测资料，充分地肯定了根据活动星系核的辐射起源而把它们划分为以热辐射为主的普通活动星系核和以非热力学辐射为主的布莱扎天体这一观点。

The inset images on the right depict, from top to bottom, a computer reconstructed image of what the background blue galaxy really looks like, just the white foreground galaxy, and just the lensed blue background galaxy.

而上面影像右侧的插入图片，从上到下依次是，背景蓝色星系真实看上去的样子，再经过计算机重新处理后的影像、白色的前景星系、以及引力透镜下的蓝色背景星系。

For this reason, NGC 404 became known to astronomers as the "Ghost of Mirach."

网易探索讯据国外媒体报道，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。

Genesis hypotheses include a galaxy collision billions of years ago and perturbative gravitational interactions involving an unusually shaped core.

此种星系的起源假说包括：在数十亿年前所发生的星系碰撞，或者是一个具有不寻常形状的星系核在紊乱重力作用下产生的。

The spaces between galaxies that are part of clusters, however, are filled with hot, rarified gas that does not get incorporated into the individual galaxies very efficiently.

然而，在星系团内部，星系与星系之间的太空中充满了炽热、稀薄的气体，无法高效地融入到各星系中去。

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。
