Pictures from space



Many people wonder why the photos from the International Space Station or space shuttle can not see the stars. It turns out, the answer is quite simple. Living in the world, we used to watch the stars in the night sky, although it would seem, in space sky is always dark as night. But all is not so simple. Day in the world thanks to a bright sky light scattering in the atmosphere. In space or on the moon is not like the atmosphere, and the sky is dark even in the daytime. But this does not mean that it is not the same "light" on earth. Looking out the window space station astronaut will see the same amount of sunlight, if not more than we can see from his window in the clearest den.

If we want to take a picture on a sunny day, we usually choose the Quick exposure and aperture of our camera. Hence, an astronaut or a companion should do the same, to take pictures of bright objects in the cosmos. Thanks to this, astronauts can get good pictures of the Earth or the Moon's surface, but the stars are not visible in photographs, as in space, they do not emit enough light to appear in the photographs.
