The principle is “the more you zoom in, the more details you see” and “you only download the data you need.” 2005) tessellation of the sky, with data organised into HEALPix cells. 2015), which is a multiresolution data format to store and visualise (all-sky) images, 3D cubes, and/or catalogues. How does this work without clogging your network? The underlying data structure are Hierarchical Progressive Surveys (HiPS, Fernique et al. In the screenshot, we show the field around the Coma Cluster of galaxies but if you find the star gamma Cas more interesting, just enter its name in the search field. This button opens a search field where you can search for your favourite object, resolved by the Sesame service (the service that transforms an object name to its coordinates on the sky).

The website has a full list of the HiPS available. The default view is the Digitised Sky Survey, but many more are available at wavelengths between radio and gamma rays (e.g., Pan-STARRS, XMM-Newton, or NVSS). This button allows you to set the look of the sky map (e.g., choose which survey to display, which colour scheme to use, and which layers to show).

The two buttons in the top left corner allow you to interact with the widget as you would with any other implementations of Aladin Lite (e.g., on the SIMBAD webpage or the ESO Archive Science Portal):
You can zoom in and out by scrolling and move the image by clicking and dragging. An example is shown in the animation below. The ipyaladin package for Python is an interactive Aladin Lite widget that can be used in your Jupyter notebook. There are a number of HiPS viewers, including the ones developed by the CDS: Aladin desktop and Aladin Lite. The HiPS of many large image surveys and some 3D cube surveys, as well as large catalogues, are available through Virtual Observatory protocols via a network of 20 HiPS nodes around the world. One method of note is the Hierarchical Progressive Surveys (HiPS), which is a tiling mechanism for viewing image and cube data. Many image and cube surveys are already at your disposal. Have you ever worked on a sample of interesting sources and wanted to quickly visualise what these sources look like at different wavelengths without going through a gazillion archives? Curtain up for ipyaladin! ipyaladin allows you to embed an Aladin Lite widget in your Jupyter notebook, look at any of the 550+ available (all) sky maps, and even overlay catalogues and tables.

This is the first article in a series of four posts where we will show how Aladin Lite can be embedded in Jupyter notebooks and used to explore images of the sky at all wavelengths using Python scripts.
The Centre de Données astronomiques de Strasbourg (CDS) provides services and tools - SIMBAD, VizieR, Aladin, and X-Match - that are designed to provide astronomers with the reference data they need. This post is the first in a series of articles on services offered by the CDS, and was written in collaboration with the CDS Python developers, who are currently working on further MOCpy and astroquery developments, and the CDS dissemination team, who are preparing for the next VO training events. This involves maintaining and developing tutorials, and mentoring at VO Schools. She works on gas and star formation in nearby galaxies, and the dissemination of the Virtual Observatory (VO) and the CDS services.
