Parallax, Cosmic Dimensions and Their Measurements

Via Brain Pickings here is an exceptionally awesome little video explaining graphically how we, as humans on the surface of a relatively minuscule celestial body in a practically infinite cosmic ocean, are able to accurately observe the stars and judge their distances.

It's worth watching more than once. You'll likely be too bedazzled by the scope of it all on first viewing, but the explanations undoubtedly become more digestible with each viewing.
