This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the orbiting DMSP satellites.

这就是地球夜晚的样子，你能找到自己喜欢的国家或者城市吗？令人吃惊的是，城市的灯光让这个任务变得很容易。人造灯光使地球表面上发达的或者有人居住的地区变得十分显眼，包括欧洲海岸，美国东部和日本。许多大城市都位于河边或者海边因此它们可以很便宜的通过船只交换物资。特别黑的地区包括南美中部，非洲，亚洲和澳洲。上面的图实际上是由轨道DMSP卫星拍摄的数百张照片组成的。

Connecting the Pipe Nebula to the bright star Antares is a flowing dark cloud nicknamed the Dark River. The murkiness of the Dark River is caused by absorption of background starlight by dust, although the nebula contains mostly hydrogen and molecular gas. Antares, the brightest star in the frame, is embedded in the colorful Rho Ophiuchi nebula clouds. The Dark River, pictured above across the upper left, spans over 20 times the angular diameter of the Moon and lies about 500 light years distant. Other types of nebula visible here include red emission nebula and the blue reflection nebula.

连接管状星云到明亮之星antares的是一个昵称为黑暗之河的流动暗色云状物。黑暗之河的阴暗色是由于尘埃吸收背景的星光而产生的，尽管星云含有大部分氢和分子气体。Antares，星体构建中最明亮的一颗，被嵌入五彩缤纷的蛇夫rho星云物内。穿越左上方黑暗之河，横越过20倍的月亮角直径并且延伸了约500光年的距离。此处其他可见星云包括红色散发状星云和蓝色反射状星云。

供给船接近空间站
The crew on board the International Space Station sometimes needs supplies. As the US Space Shuttle fleet prepares to return to flight, supplies usually now come from a robot Progress supply vessel launched from Kazakhstan. Pictured above, a Progress ship approaches the ISS on May 27, delivering over 2,500 kilograms of food, water, fuel and other important items. The supply ship soon docked with the Zvezda Service Module while orbiting the Earth over 300 kilometers over central Asia.

在国际空间站上的成员有时需要补给。由于美国的太空梭船队准备返航，现在补给经常从哈萨克斯坦发射的机械助进补给船供给。这张照片，一艘飞船在五月27日接近ISS，运送超过2.5吨的食物，水，燃料和其他重要物品。当绕轨道运行地球超过300公里越过中亚后供给船很快用zvezda服务登月舱靠岸。

The Whirlpool Galaxy in Dust and Stars 星尘之间的漩涡星系
The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. The above image is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope highlighting sharp features normally too red to be seen. 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. Astronomers speculate that M51's spiral structure is primarily due to its gravitational interaction with a smaller galaxy just off the top of this digitally sharpened image.

日食的影子
Here is what the Earth looks like during a solar eclipse. The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 kilometers per hour. Only observers near the center of the dark circle see a total solar eclipse - others see a partial eclipse where only part of the Sun appears blocked by the Moon. This spectacular picture of the 1999 August 11 solar eclipse was one of the last ever taken from the Mir space station, which was deorbited in a controlled re-entry in 2001.
