The Virtual Astronomical Observatory (VAO) is part of a worldwide effort called the Virtual Observatory (VO) that aims to link astronomy data and services.
A summary of Virtual Observatory news for the US astronomical research community. Supported and compiled by the US Virtual Astronomical Observatory.
Find, plot, and fit spectral energy distributions (SEDs) with this desktop application.
Perform fast positional cross-matches between an input table of up to 1 million sources and common astronomical source catalogs.
Discover time-series data from three major archives & analyze them with the NASA Exoplanet Archive periodogram application.
The US Virtual Astronomical Observatory (VAO) has released VOClient – a software package that enables direct access to services in the VO from a Unix terminal or scripting environment. The VOClient command-line tools allow you to discover archives and catalogs through queries to the VAO Registry, search-for and download images, spectra, and catalogs, and interoperate with other VO-compatible tools. These tools can be used to create customized access to VO services, new VO tools or enhancements to existing software by adding VO capabilities.
