“The Universe is now being explored systematically, in a panchromatic way, over a range of spatial and temporal scales that lead to a more complete, and less biased understanding of its constituents, their evolution, their origins, and the physical processes governing them.” • Towards a National Virtual Observatory Tracking the Heavens Hubble Telescope Palomar Telescope Sloan Telescope
The Virtual Observatory • Premise: most observatory data is (or could be) online • So, the Internet is the world’s best telescope: • It has data on every part of the sky • In every measured spectral band: optical, x-ray, radio.. • It’s as deep as the best instruments • It is up when you are up • The “seeing” is always great • It’s a smart telescope: links objects and data to literature on them • Software has became a major expense • Share, standardize, reuse.. Slide modified from Alex Szalay, NVO
Downloading the Night Sky • The National Virtual Observatory • Astronomy community came together to set standards for services and data • Interoperable, multi-terabyte online databases • Technology-enabled, science-driven. • NVO combines over 100 TB of data from 50 ground and space-based telescopes and instruments to create a comprehensive picture of the heavens • Sloan Digital Sky Survey, Hubble Space Telescope, Two Micron All Sky Survey, National Radio Astronomy Observatory, etc. Hubble Telescope Palomar Telescope Sloan Telescope
Using Technology to Evolve Astronomy • Looking for • Needles in haystacks – the Higgs particle • Haystacks -- Dark matter, Dark energy • Statistical analysis often deals with • Creating uniform samples • Data filtering • Assembling relevant subsets • Censoring bad data • “Likelihood” calculations • Hypothesis testing, etc. • Traditionally these are performed on files, most of these tasks are much better done inside a database Slide modified from Alex Szalay, NVO
How NVO Works • Raw data comes from large-scale telescopes • Telescopes provide daily sweep of the sky, scientists “clean data” which is then converted from temporal to spatial data, allowing indexing over both dimensions. • All NVO data on website available to the public without restriction (by community agreement, all data public after 1 year) • NVO databases distributed and mirrored at multiple sites Crab Nebula Palomar Telescope
Making Discoveries Using the NVO Scientists at Johns Hopkins, Caltech and other institutions confirmed the discovery of a new brown dwarf. Search time on 5,000,000 files went from months to minutes using NVO database tools and technologies. Brown dwarfs are often called the “missing link” in the study of star formations. They are considered small, cool “failed stars”.
Cyberinfrastructure and NVO • Sky surveys from major telescopes indexed and catalogued in NVO databases by time and spatial location using Storage Resource Broker and other tools • NVO collections archived at multiple sites, accessed by Grid technologies • Software tools and web portals create an environment for ingestion of new information, mining, discovery and dissemination
Moving the Earth The earth is constantly evolving through the movement of “plates” Using plate tectonics, the Earth's outer shell (lithosphere) is posited to consist of seven large and many smaller moving plates. As the plates move, their boundaries collide, spread apart or slide past one another, resulting in geological processes such as earthquakes, volcanoes and the development of mountains, typically at plate boundaries.
Earthquake Simulations Major Earthquakes on the San Andreas Fault, 1680-present • Simulation results provide new scientific information enabling better • Estimation of seismic risk • Emergency preparation, response and planning • Design of next generation of earthquake-resistant structures • Results provide immense societal benefits which can help in saving many lives and billions in economic losses • Geoscience researchers can now use massive amount of geological, historical, and environmental data to simulate natural disasters such as earthquakes. • Focus is on understanding big earthquakes and their impact. • Simulations combine large-scale data collections, high-resolution models, supercomputer runs 1906 M 7.8 ? 1857 M 7.8 1680 M 7.7 How dangerous is the San Andreas Fault?
TeraShakesimulates a 7.7 earthquake along the southern San Andreas fault close to LA using seismic, geophysical, and other data from the Southern California Earthquake Center
HowTerashake Works • How TeraShake simulates earthquakes: • Divide up Southern California into “blocks” • For each block, get all the data on ground surface composition, geological structures, fault information, etc.

This dream has been accomplished.” Bernard Minster, Scripps Institute of Oceanography
SURA Coastal Ocean Observing and Prediction‘SCOOP’ scoop.sura.org “With SDSC’s Storage Resource Broker software we can access these data sets in DataCentral through the Grid from anywhere in the world.” This will help SCOOP researchers make their data available to the wider coastal modeling community. The data for the 2005 hurricane season are particularly valuable, and the SCOOP collection in DataCentral covers Katrina, Rita, and Wilma—three of the strongest category five hurricanes on record. Simulations predicting the approach of Katrina to New Orleans. The wind fields of Katrina are shown as white/grey ribbons, clearly showing the hurricane vortex. The yellow to red coloring beneath the eye of the hurricane shows the storm surge moving cross the gulf, pushed by the hurricane’s wind. W. Benger and S. Venkataraman, CCT/LSU.

AMANDA(Antarctic Muon And Neutrino Detector Array) The dream of constructing a radically different telescope has been realized by the innovative AMANDA-II project. Instead of sensing light, like all telescopes since the time of Galileo, AMANDA responds to a fundamental particle called a neutrino. Neutrino messengers provide a startlingly new view of the Universe. The 20TB/yr produced requires manipulation, processing, filtering, and Monte Carlo data analyses for the search of high energy neutrinos. A full data analysis requires a total space of 40TB/yr. amanda.uci.edu AMANDA -II MAPO South Pole Airport 1500 m Amundsen-Scott South Pole Station 2000 m
