SUMMARY: A new astronomical survey is in the works to help uncover the source of the mysterious dark energy which is accelerating the expansion of the Universe. Set to begin in 2009, the Dark Energy Survey will collect data on approximately 300 million galaxies, reaching back two-thirds of the history of the Universe. A 520-megapixel camera will be installed onto the 4-metre Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile, allowing astronomers to survey the sky 10 times faster than they could before.

I'm almost as interested about their jpegs on steroids that will record this data. How will they label and identify so much? Methinks they are biting a bit too broad a bite, much more than they can chew. Then again, it could be a broad scan before drilling down on interesting areas approach. Would this standardized survey data be available to other studies as well? I wonder if you can do spectral-type or such analysis from these? I'm sure it will be helpful watching for distribution patterns that might also be interesting.

It is amazing sometimes just how rapidly our technology for examining the sky and different aspects of the cosmos are advancing. This new instrument will do new great things, and based on the success it will have, even better instruments will come online for more elaborate versions of the same task a decade later.

This camera will return more results than simply a study of the history of dark energy.
