Astronomical data avalanche

• Breakthrough in telescope, detector and computer
  technology allow astronomical instruments to
  produce terabytes of images and catalogs. This
  datasets will cover the sky in different
  wavebands
• In a few years it will be easier to dial-up a
  part of the sky than wait many months to access a
  telescope

3
Virtual Observatory

• Over the past years the concept of the Virtual
  Observatory has emerged rapidly to address the
  data management, analysis, distribution and
  interoperability challenges
• The VO is a system in which the vast astronomical
  archives and databases around the world, together
  with analysis tools and computational services
  are linked together into an integrated facility

4
Virtual Observatories

• Sixteen VO projects are now funded through
  national and international programs, and all
  projects work together under the International
  Virtual Observatory Alliance to share expertise
  and develop common standards and infrastructures
  for data exchange and interoperability
• A number of the VO projects are using science
  prototypes, or demonstration projects to show the
  user community the benefits of the federated
  archives, catalogs and computational services

o/

• The IVOA (R. J. Hanisch P. J. Quinn)
• IVOA Guidelines for Participation (R. J. Hanisch
  P. J. Quinn)
• Documents and Standards

7
Standards are necessary

• providing access for 103 users to 107 resources
  of 10 kinds of permission
• translation of names to universal dictionary
  (40-50 designations for Sirius or Vega, 250
  different names for Johnson V-magnitude)
• names of sources like "gcvs.sternberg.on-line"
• query language, resource discovery, resource
  ranking, specific information (filters,
  instruments, detectors, image quality etc.),
  units standardisation

8
What is VO?

• We will bring astronomical data from any
  telescope in the world to any computer, any time,
  anywhere.Parts of VO are ready now. A grand
  world wide scheme 5-10 years.Less than one
  Advanced Tactical Fighter aircraft.

When it will be ready?
What will it cost?

Digitizing of glass libraries

• Russia (and fSU countries) participate in the
  International project on digitizing of glass
  libraries of astronomical observatories.
• The project is led by Sofia Sky Archive Data
  Centre.
• We have got funding, and we have bought two Epson
  Expression 1640XL scanners, which allow us to
  scan plates up to 30x30 cm. Similar scanners are
  widely used in Bulgaria as well as in Hungary and
  Germany.

Russian Virtual Observatory is merged naturally
into the International Virtual Observatory. Russi
an Virtual Observatory is an open project, any
collaboration with other countries and institutes
is welcome and required (e. g., participation in
federated demos)
