星系

It is reported that the Whale Galaxy, as large as Milky Way, is next to the northern area of Canes Venatici.

据悉，鲸星系的大小类似于银河系，它靠近狼犬星座北部区域。

Anyone with a good pair of binoculars, however, can see this Whirlpool toward the constellation of Canes Venatici. M51 is a spiral galaxy of type Sc and is the dominant member of a whole group of galaxies.

但如果有人的眼睛足够好就可以向Canes Venatici星群眺望看见它。M51是一种Sc形态的螺旋状星云并且是整个星系中的领导成员之一。

So, using infrared light, astronomers have just found a small galaxy of about a billion stars in the constellation Canis Major, that is -- astonishingly -- only about 25,000 light-years away from the Sun.

碰巧，通过红外线，天文学家已经发现了一个较小的由数十亿恒星组成的名为"Canis Major"星座的星系，这是非常令人惊讶的！

In the direction of the constellation Canis Major, two spiral galaxies pass by each other like majestic ships in the night.

在大犬座方向，两个螺旋形的星系正在彼此穿过，好像暗夜里威严的航船。

The Canis Major dwarf galaxy is not faring well in its gravitational battle with the Milky Way, and there are streamers of stars being pulled off the smaller galaxy onto the disk of our own.

Canis Major星系在与我们的银河的引力之争中处于劣势，已经有一条由被拖出的恒星的彩带被从Canis Major拉出，并被引入银河系大圆盘中。

Brilliant Canopus, second brightest star in the night, and our neighboring galaxies the Large and Small Magellanic clouds, are also included in the scene.

光辉的老人星，夜空第二亮恒星，和我们的近邻星系大小麦哲伦星云，也在这镜头中。

The insets to the right of the composite show how each telescope individually views the Cartwheel.

右侧插入的小图是每架望远镜各自眼中的车轮星系。

Astronomers think a smaller galaxy, possibly one of two galaxies seen here, passed through the center of the Cartwheel galaxy about 100 million years ago.

天文学家认为，一个较小的银河，可能是两个银河这里看到，通过中心的车轮星系大约一亿年前。

Hubble's view of the Cartwheel is colored green in the larger composite and GALEX's UV view is colored blue.

在合成图中，哈勃所见的车轮星系以绿色表示， GALEX 所见的 UV 图以蓝表示。

The Cartwheel contains an unusually large number of these black hole X-ray sources, because many massive stars formed in the rim.

车轮星系中，这样的黑洞 X 射线源出乎寻常地多，这是由于有大量的大质量恒星在外缘形成。

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。
