But it's not hard, try astronomical image of the day or the Hubble page, or any amateur astronomy club site like mine Walsallastro .co.uk.
They aren't. You can find real images of Earth, of the moon, and of other planets all over the Internet. The only difficulty is distinguishing th real ones from the fake ones, because sometimes the real ones look too good to be real, etc.
However you're simply not going to find the images you are probably thinking of. There simply aren't any images of deep outer space or other galaxies, etc. because we don't really have anything out there to take the pictures, and it would take much too long to send them back once they were taken. In fact, our view of the universe, indeed even our own solar system, is extremely limited, as practically all of our hardware is very close to our own planet. So, all you are really going to find is images of things you have already seen, no doubt.
Also, most images of deep space are simply taken from the same thing we already view it from: a telescope. It's just that the telescope is located in orbit and is much more powerful. However, it isn't that much farther away from the telescopes on Earth where we get most of our images from. It is just a little bit closer to the cosmos, but not much, so most of the images are going to look roughly the same, maybe just a tad higher quality.
參考: Google images search.
Search for the missions regarding Saturn's rings and Titan, as it did fly bys of the moon, earth, and other planets.
Search for images of the Hubble.
XD, you're funny but yeah, just google and you'll stumble upon something.
It's worst though when dummys say,"YO THEY PHOTOSHOPPED THIS."
