I forget who said it, but there's a quote about how _of course_ we know more about space than the bottom of the ocean - in space we only have to deal with one atmosphere.

>only have to deal with one atmosphere.
A difference of one atmosphere?
There’s only one atmosphere of pressure from inside to outside. Under the sea the direction is reversed and pressure is much higher.
Spacecraft are pressurized to much less than one atmosphere, because it reduces the stress on the craft, and the weight of the air supply.

Fry: "How many atmospheres can the ship withstand?" Professor: "Well, it's a spaceship, so I'd say anywhere between zero and one." s02e12
The one atmosphere that telescopes are looking through. It is nowhere near as problematic as looking through seawater.
But space telescopes exist where you don't have to deal with one atmosphere.
