Outline
• Why do we need Virtual Observatories?
• Are they operational yet?
• Who is behind them?

Virtual Observatories: The goal
• Efficient management of the information available in astronomical archives.
• … BUT …accessing to on-line resources through high capacity networks is almost a daily task for
most of the astronomers…
So, what else is needed? So, what else is needed?

A real-life example:“I want to get all what is known about Vega”
Finding the pieces:
• 239 000 results
• Many unrefereed sources

Finding the pieces (II)
• But… is there anything else out there?– Need of astronomical “yellow pages”
VO makes the discovery process more efficient and reliable thanks to Registries.

A real-life example:“I want to get all what is known about Vega”
Gathering the pieces
• Astronomers need to learn about different user interfaces, access and download procedures.
• Tedious, inefficient and painful task.

The situation is getting worse as astronomical data is growing exponentially
Large area surveys: future
Paranal. Comissioning 2008 - 100 TB/yr
Cerro Pachón. First light 2014 - 5 PB/yr
Full operation: 2020 - 100 PB/yr

SVO: Objectives
• Construction of a community of science users:
- Scientific Workshops.
- Support to VO science programmes
- Production of on-line tutorials
- This school
• Development of IVOA standards and services
• Support to data publishing in the VO
• Education and Outreach activities.

Summary• The VO provides new ways to discover, access, and analyze
data from astronomical data collections worldwide.
• All major data centers provide VO- compatible interfaces to their data.
• New and/or more efficient science.
• VO Science is already a reality.
