### What is the VO? | ||
|
||
The Virtual Observatory (VO) aims to provide a research environment that will | ||
open up new possibilities for scientific research based on data discovery, | ||
efficient data access, and interoperability. The vision is of global astronomy | ||
archives connected via the VO to form a multiwavelength digital sky that can be | ||
searched, visualized, and analyzed in new and innovative ways. VO projects | ||
worldwide working toward this vision are already providing science capabilities | ||
with new tools and services. This newsletter, aimed at astronomers, highlights | ||
VO tools and technologies for doing astronomy research, recent papers, and | ||
upcoming events | ||
|
||
### What is the IVOA? | ||
|
||
The International Virtual Observatory Alliance (IVOA) was formed in June 2002 | ||
with a mission to "facilitate the international coordination and collaboration | ||
necessary for the development and deployment of the tools, systems, and | ||
organizational structures necessary to enable the international utilization of | ||
astronomical archives as an integrated and interoperating virtual observatory." | ||
The IVOA now comprises 16 VO projects from Armenia, Australia, Canada, China, | ||
Europe, France, Germany, Hungary, India, Italy, Japan, Korea, Russia, Spain, the | ||
United Kingdom, and the United States. Membership is open to other national and | ||
international projects according to the IVOA Guidelines for Participation. You | ||
can read more about the IVOA and what we do at <http://www.ivoa.net/pub/info/>. | ||

# VO applications highlights | ||
|
||
### AstroGrid VO Desktop Suite | ||
|
||
{{< side-image image="astrogrid_sh_thumb.jpg" >}} | ||
|
||
This newly released suite includes several interlinked tools including an | ||
iTunes-inspired browser, VOExplorer, which allows you to search, filter, save | ||
and bookmark your favourite VO resources. You can search for data by position, | ||
or run more complex queries where available. AstroRuntime software runs in the | ||
background and allows seamless visualization of selected catalogues, images, | ||
spectra, and time domain datasets in VO enabled tools. You can also save and | ||
share files in VOSpace and invoke remote applications. For those wanting | ||
command-line access, all the functionality of the VODesktop is available using | ||
python scripting, with IDL to follow. | ||
|
||

|
||
### VirGO v1.3.1 | ||
|
||
{{< side-image image="VirGOLogo.png" >}} | ||
|
||
VirGO is the next generation visual browser for the ESO Science Archive | ||
Facility. VirGO provides an easy access to millions of raw frames in a visual | ||
and intuitive way. Its main feature is the performance of real-time access and | ||
graphical display of a large number of observations by showing instrumental | ||
footprints and image previews, and the selection and filtering for subsequent | ||
retrieval. It uses the DSS as background images and allows the user to view the | ||
sky in a "real-life mode" as seen from the main ESO sites. Data interfaces are | ||
based on VO standards, enabling access to images and spectra hosted by other | ||
data centers. VirGO can also exchange data with other VO applications through | ||
the PLASTIC messaging system. A large fraction of ESO's non proprietary science | ||
products are already accessible through VirGO and more are to come, including | ||
the data products from the ESO Public Surveys. | ||
|

||
### VO-CLI - Command Line Tools for the VO | ||
|
||
{{< side-image image="m33_vocli.png" >}} | ||
|
||
VO-CLI is a package of command-line tools that provides familiar unix-like | ||
access to VO services while hiding much of the complexity of the underlying VO | ||
framework from novice users. These tools can be used from the desktop, in | ||
various scripting environments, or in back-end CGI scripting to support web | ||
applications, and have the ability to output results in a variety of formats. | ||
Another key feature of the package is the ability to optionally use "common" | ||
names for both objects and VO resources; these names are resolved internally to | ||
sky positions or service URLs. "Power users" will quickly become proficient | ||
using the command-line interface; a web interface to the tasks is also available | ||
for novice users or those wishing to experiment. | ||

|
||
### Large Images in Aladin | ||
|
||
{{< side-image image="aladin_small.jpg" >}} | ||
|
||
The latest version of the Aladin software provided by CDS in Strasbourg now | ||
supports use of large images, unlimited by the local computer memory. Other | ||
changes include image transparency, automatic scale and orientation adjustment, | ||
Russian & traditional Chinese translation, and more. Aladin is an interactive | ||
software sky atlas allowing the user to visualize digitized astronomical images, | ||
superimpose entries from astronomical catalogues or databases, and interactively | ||
access related data and information from the Simbad database, the VizieR service | ||
and other archives for all known sources in the field | ||
|
