The reason this is too kool is that it was imaged with a ground-based telescope. Keck II on Hawaii with adaptive optics. Io used to be either a dot in the big telescope or a satellite image. New stuff.

ping-you like this sort of thing, right?

Cool.

...adaptive optics...

By what it's called, I assume it's done in real-time (and done physically). I have audio software that removes noise (by first sampling the noise by itself and then removing it from the signal) but it's "after the fact".

Can you explain to a layman like myself how adaptive optics work? Seems Herculean to me.
