The Aladin sky atlas is available in two modes:

  • Aladin Desktop, a regular Desktop application
  • Aladin Lite a Javascript Web application.

Aladin Desktop

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.

Aladin Lite

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 WebGL 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.

We also offer an experimental viewer to visualize planetary surfaces HiPS datasets

If you are you a developer interested in integrating Aladin Lite in your project, have a look at the dedicated documentation.

Aladin Lite is also available as a widget for Python notebooks: ipyaladin.

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 1100+ HiPS surveys available for 500TB 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, CADきゃどC, MAST, HEASARC, NRAO, ROE, IMCCE, etc), and obviously, local user data.
