Our eyes are pretty amazing. According to
this site, our eyes can see the light from one candle from 30 miles away. But the objects in our solar system are much farther away then that, and objects outside our solar system are even farther away!
Scientists use telescopes to see objects in space that are much farther away. Telescopes that are in space, like on satellites, can see an incredibly long distance and can also take some spectacular photos.
