Google Reaches for the Stars

One of the most important shifts in science at the moment is towards dealing with the digital deluge. Whether in the field of genomics, particle physics or astronomy, science is starting to produce data in not just gigabytes, or even terabytes, but petabytes, exabytes and beyond (zettabytes, yottabytes, etc.).

Take the Large Synoptic Survey Telescope, for starters:

The Large Synoptic Survey Telescope (LSST) is a proposed ground-based 8.4-meter, 10 square-degree-field telescope that will provide digital imaging of faint astronomical objects across the entire sky, night after night. In a relentless campaign of 15 second exposures, LSST will cover the available sky every three nights, opening a movie-like window on objects that change or move on rapid timescales: exploding supernovae, potentially hazardous near-Earth asteroids, and distant Kuiper Belt Objects. The superb images from the LSST will also be used to trace billions of remote galaxies and measure the distortions in their shapes produced by lumps of Dark Matter, providing multiple tests of the mysterious Dark Energy.

How much data?

Over 30 thousand gigabytes (30TB) of images will be generated every night during the decade-long LSST sky survey.

Or for those of you without calculators, that's 10x365x30x1,000,000,000,000 bytes, roughly 100 petabytes. And where there's data, there's also information; and where there's information...there's Google:

Google has joined a group of nineteen universities and national labs that are building the Large Synoptic Survey Telescope (LSST).

"Partnering with Google will significantly enhance our ability to convert LSST data to knowledge," said University of California, Davis, Professor and LSST Director J. Anthony Tyson. "LSST will change the way we observe the universe by mapping the visible sky deeply, rapidly, and continuously. It will open entirely new windows on our universe, yielding discoveries in a variety of areas of astronomy and fundamental physics. Innovations in data management will play a central role."
