The Milky Way in the Sky - Is That Really What We Need?

It all comes down to what wave length are you looking in. If we go out and look at it with our own eyeballs, all we see is glowiness. And where the milky way gets bigger, that's the gas and dust, an optical that we can't look through. It's only when you combine an entire planet's worth of of telescopes on one hemisphere that you can start to get this kind of a resolution. We don't have the capacity to combine the light from multiple telescopes in infared optic x ray or any of these other shorter wave lengths. We just can't do it in the same way.
