1. GoogleSky Alberto Conti Space Telescope Science Institute
3. Established in 1997 as NASA’s Optical and Ultraviolet Data Archive Supports Active missions: HST, GALEX, Kepler,... Legacy missions: IUE, FUSE, EUVE,... Optical & UV Data Archive
4. The NASA Astrophysics Data System (ADS) High Energy Astrophysics Science Archive Research Center (HEASARC) Infrared Science Archive (IRSA) & IPAC Extragalactic Database (NED) Archive Centers Publications X-ray and Gamma Ray Infrared
5. World-wide technical and scientific leadership in archive system design Secure storage and reliable retrieval services for data from HST and all MAST-supported missions User-friendly and scientifically useful search and cross-correlation tools Development and support for inter-archive communication and data transfer standards MAST
7. Challenges for the Future Space is big! For one picture you need a 2 Trillion pixels camera! Monochrome : 4 Terabytes or 6% of the Library of Congress Color: 100 Terabytes or the 40% more than the entire Library of Congress Time: 10 Petabytes or 150 times the entire Library of Congress New analysis & visualization tools are required
8. Massive amounts of information Computer Science Biology Economics Medicine Government Astronomy

10. Astronomy is changing Growth over 25 years is a factor of 30 in glass, 3000 in pixels Detectors follow Moore’s Law Total data doubles every year

12. Astronomy is special! No commercial value Ideal testbed for complex algorithms Interesting problems Plenty of data, plenty of dimensions!
13. 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: GoogleSky
