The Aladin sky atlas is available in two modes: Aladin Desktop, a regular application and Aladin Lite an HTML5 javascript web widget.

Aladin Desktop 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...) Aladin lite 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...)

Available data

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 185+ HiPS surveys available for 48TB of pixels provided by 3 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.
