ELI5 why can NASA get super high resolution images of galaxies hundreds and thousands of light years away, but struggle and cannot get even a decent image of Pluto?

I did the Google-ing like the rules say but the journal articles are very complex with equations and "refraction property data of heat waves through various gasses", and the science news articles don't really say why either. So, I have come here for some dumbed down science and explanation.

The same reason you can get a brilliant image of the mountain 100 miles away in the day with your camera phone but a professional photographer wouldn't be able to make out the detail of a flea across the room in the dark

It's easy to take pictures of huge bright things, even if they're far away.  TINY things are hard to get a picture of, even if they're relatively closer, especially if they don't give off much light.
