Aladin is an interactive sky atlas allowing the user
to visualize digitized astronomical images or full surveys,
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 astronomical objects in the field.
The Aladin sky atlas is available in two modes:
Aladin Desktop, a regular application
is a widely-used java tool capable of addressing challenges such as locating data of interest, accessing and exploring distributed datasets, visualizing multi-wavelength data. Compliance with existing or emerging VO
standards, interconnection with other visualisation or analysis tools, ability to easily compare heterogeneous data are key topics allowing Aladin to be a powerful data exploration and integration tool as well as a science enabler. Aladin Desktop is based on Java techonology. It requires a classical installation on the user machine. (→ more)
is a lightweight version of the Aladin tool, running in the browser and geared towards simple visualization of a sky region. Aladin lite is powered by the HTML5 canvas technology, currently supported by any modern browser. Aladin lite is easily embeddable on any web page
and can also be controlled through a Javacript API
. It is dedicated to replace the previous Aladin Java applet
technology in the medium term. (→ more)
Aladin Desktop & Aladin Lite use reprocessed data based on
HiPS technology (Hierarchical Progressive
Survey) with the capability to zoom and pan on any regions of the
surveys. There are about 250+ HiPS surveys available for
50TB of pixels provided by several collaborative servers.
Aladin Desktop provides direct data access to most of the astronomical servers over the world (CDS, NED, ESO, CADC, MAST, HEASARC, NRAO, ROE, IMCCE, etc), and obviously, local user data.
