Because the objects that it is viewing are BILLIONS of light years long and wide. All of those nebulas you see are absolutely massive, they just not be incredibly bright. This is in contrast to Pluto which cannot be seen very well from the hubble space telescope. It is bright enough, but too small. Fun fact, you can see the [orion nebula](https://www.youtube.com/watch?v=YIGRpctqZs0) with just a camera.
