Even the advent of the telescope didn’t change this much. Sure, astronomers could see fainter objects like the moons of Jupiter, and resolve point-like planets into disks with structures of color and shade. But the human visual system remained an integral component, limiting data-gathering to what could be seen and sketched by human observers in real time.

Now, thanks to distributed computing, there’s an easier way to view and record this information — which is transforming ‘the oldest science.’ With the year 2009 marking the International Year of Astronomy (and the 400th anniversary of Galileo’s creation of the telescope) what is this “bright new age of astronomy?”
