Worthy Of Dr. Sagan


You guys. Phil Plait at the Bad Astronomy blog has outdone himself. He’s describing a massive, massive infrared survey of the sky–over 150 billion pixels, showing a billion stars–and he does it really, really well (click through to see how he gives an idea of scale). But it’s at the end of the post that he gets really Sagan-esque:

Think on this: there are a billion stars in that image alone, but that’s less than 1% of the total number of stars in our galaxy! As deep and broad as this amazing picture is, it’s a tiny slice of our local Universe.

And once again, we’ve reached the point where I’m out of words. Our puny brains, evolved to count the number of our fingers and toes, to grasp only what’s within reach, to picture only what we can immediately see — balk at these images.

But… we took them. Human beings looked up and wondered, looked around and observed, looked out and discovered. In our quest to seek ever more knowledge, we built the tools needed to make these pictures: the telescopes, the detectors, the computers. And all along, the power behind that magnificent work was our squishy pink brains.

A billion stars in one shot, thanks to a fleshy mass of collected neurons weighing a kilogram or so. The Universe is amazing, but so are we.
