ELI5: The probe sent to Pluto is about to come out of hibernation, giving us the best glimpse of Pluto since it's discovery. Why can't we just point the Hubble at it and get crystal clear photos of Pluto when we can use the same telescope for peering into the edges of the visible universe?

Your phone can take a picture of Mt Rushmore from 1,000 feet away but can't take a picture of an ant from 20 feet away.

Hubble is looking at supermassive things far away that generate a lot of light but Pluto is very small and doesn't reflect a lot of light.
