New Science Paradigm for Astronomy Saturday, March 7, 2009

Astronomy is changing Old days: photographic plates 1960: astronomical goes digital ? Instruments collect 100 GB/ night Detectors follow Moore’s Law Total data doubles every 2 years Growth over 25 years is a factor of 30 in glass, 3000 in pixels Saturday, March 7, 2009

Space is big! For one picture you need a 2 Trillion pixels camera! Challenges for the Future Saturday, March 7, 2009

Monochrome : 4 Terabytes or 5% of the Library of Congress Challenges for the Future Saturday, March 7, 2009

Color: 100 Terabytes or the 21% more than the entire Library of Congress Challenges for the Future Saturday, March 7, 2009

Time: 10 Petabytes or 120 times the entire Library of Congress Challenges for the Future Saturday, March 7, 2009

New analysis & visualization tools are required Challenges for the Future Saturday, March 7, 2009

Adapt or Perish Google Earth, Microsoft Virtual Earth have revolutionized the way we look at our planet. We proposed a new synergistic approach to the challenge of bringing the universe to our desktops Saturday, March 7, 2009

Old Public Data Access •Many observatories •Individual interfaces Mission A Mission B Observatory X Mission C Observatory Y Saturday, March 7, 2009

New Science Paradigm: First Iteration } •Data Standards •Protocols Mission A Mission B Observatory X Mission C Observatory Y Saturday, March 7, 2009

New Science Paradigm: Second Iteration Data Standards, Protocols, Mining Tools Mission A Mission B Metadata Observatory X Mission C Observatory Y Saturday, March 7, 2009

New Science Paradigm Problems • Technology is trumping science • Many distributed services are unreliable • Little idea of what users are doing and why • Complex, difficult to use • Moving data around is hard • Hard for user to publish their own data Saturday, March 7, 2009

Challenges • Reduce obstacles to Capturing, Organizing, Summarizing, Analyzing,Visualizing, and Curating • Consider data and algorithms as “the product” • Adopt semantic technologies to enable automated metadata tagging, clustering and mining • Transition to the new astronomy • Sociological issues 19 Saturday, March 7, 2009

• We must partner with other academic disciplines: Computer Science, Statistics, ... • We must leverage partnerships with industry interested in enabling Science 2.0 • We must learn to be humble and ask for help • We must remember that we have the greatest datasets in the world (universe really!)
