I will introduce and describe Aladin Lite1, a lightweight interactive sky viewer running natively in the browser. For convenience, you can export it to a HEALPix map, or share it with the community through Aladin from your web site or eventually from the CDS image collection.Īladin Lite: Embed your Sky in the Browser From the images you have selected, it will compose a mosaic with several resolutions (HEALPix tessellation), and organize them to allow their progressive display in Aladin. Now, we provide a new tool to build an all- sky view with your own images. The maps are constructed by mosaicing individual images. To improve on this capability, some catalogs and maps have been built from many surveys (e.g., DSS, IRIS, GLIMPSE, SDSS, 2MASS) in mixed resolutions, allowing progressive display. This all- sky view is particularly useful for visualization of very large objects and, with coverage of the whole sky, maps from the Planck satellite. Bonnarel, F.įrom the need to extend the display outside the boundaries of a single image, the Aladin team recently developed a new feature to visualize wide areas or even all of the sky. Aladin Lite is powered by HTML5 canvas technology and is easily embeddable on any web page and can also be controlled through a Javacript API. It allows visualization of image surveys (JPEG multi-resolution HEALPix all- sky surveys) and permits superimposing tabular (VOTable) and footprints (STC-S) data. These improvements will also benefit to ipyaladin, the widget enabling the usage of Aladin Lite in Jupyter notebooks.Aladin Lite: Lightweight sky atlas for browsersĪladin Lite is a lightweight version of the Aladin tool, running in the browser and geared towards simple visualization of a sky region. Short video footage sequences will demonstrate the existing prototype throughout the presentation. We will also outline the technical challenges and limitations we encountered.

We will give an overview on the architecture used to develop these new functionalities, based on existing Rust code transpiled to WebAssembly, a portable high-performance low-level bytecode for the web supported in all modern browsers. While keeping the strengths of the original code, Aladin version 3 will introduce several new features: support of multiple projections (Aitoff, Mollweide, Orthographic, Mercator), support of FITS tiles, display of FITS images, heatmaps visualisation of catalogue data, improved rendering pipeline and coordinates grids.
We present a major overhaul of Aladin Lite taking advantage of the GPU with WebGL, and which responds to requests of users, developers and integrators in a context where browser-based applications and science analysis platforms are increasingly important.

Aladin Lite has been adopted as the sky visualisation component of popular applications: ESA Sky, ESO Science Archive or ALMA Science Archive.

Designed to be easy to embed, it is now used in more than fifty websites and portals in the professional astronomy community. Since its first version in 2013, Aladin Lite has gained significant traction and usage as an HiPS viewer running in the browser.
