The galaxies emit light that travels to us. The satelites use large mirrors to collect the light and long time exposures to take the pictures.

You don't need satellites to take pictures of galaxies. You can see them from your back yard with ordinary amateur telescopes. Galaxies may be far away, but each contains millions of stars, and they put out a lot of light, so that galaxies are readily visible. You can even see one or two galaxies with your naked eye from a dark location; no telescope required!

The Hubble Space Telescope is the only satellite-borne telescope that takes deep-space pictures. It's able to get pictures of the farthest objects in the observable universe by first of all being above the distorting effects of Earth's atmosphere, and by making long-time exposures.

This is possible by revolutions in technology. Super-high quality cameras move around the earth and little by little takes snapshots. When we see them on maps.yahoo.com, maps.google.com, and maps.live.com, they are composed together to look as if it was all taken at one time. As for the birds-eye view of locations, they probably take pictures from helicopters or some air-hovering object.

They don't. Cameras on telescopes do. There are a few telescopes in space, the Hubble Space Telescope being the most famous one, but most satellites do not have telescopes or cameras and they don't take pictures at all.

They use a disposable camera and when full they eject it over the US and hope that someone finds it intact and delivers it to nasa. At least that's how nasa would do it! Of course this approach would cost at least 12 billion per picture before developing!

Most deep space photos are taken from the Hubble and or observatory's around the world

very strong lenses and mirrors. thats really it to be honest. there is no killer mushroom sitting in the telescope that flies around with a camera. lenses and mirrors. yep.

With a telephoto camera.

They take a picture, and we look at it.
