It used to be that, in astronomy, a small team of people could look at photos of a few thousand galaxies and classify and catalog them relatively easily. But now, with a new generation of robotic telescopes scanning the skies constantly and producing millions of images, that's become next to impossible.
It will be the mother of all telescopes, and you can bet it will do for astronomy what genome sequencing is doing for biology. The clumsy, if utilitarian, name of this mirrored monster is Large Synoptic Survey Telescope, or LSST. You can't use it yet, but a peak in the Chilean Andes has been decapitated to provide a level spot for placement.
