Chromscope in the Wild

There are a number of other instances of Chromoscope being used “in the wild”, including by people other than the original developers.



Planckoscope is a bespoke version of Chromoscope designed to show images from the Planck satellite. It includes an additional “menu” in the lower right, and a number of overlay layers. There are two views, one (the default) showing the various “components” (dust, synchrotron, carbon monoxide etc.), and another showing a range of frequencies. There is also a “Polarisation” check box, which shows a polarisation view for frequencies/components for which there is polarisation information.

Planckscope was created for an exhibit at the 2015 Royal Society Summer Science Exhibition. The source code is available on GitHub, and the tilesets and full-sky images for Planckoscope can be downloaded here.

The same all-sky images are displayed, shown as a 3D sphere which can be rotated, at This site was created by Damien George.

Herschel Space Observatory


The Online Showcase of Herschel Images (OSHI), which was hosted and maintained by ESA, was based on Chromoscope (though doesn’t show multiple wavelengths). Note that OSHI is no longer available

UK Herschel website

A range of the results from the Herschel Space Observatory are shown on the UK Herschel website. It uses “KML markers” to generate and display icons for the results, which link to the original news stories.


The GLEAM (GaLactic and Extragalactic All-sky MWA Survey) collaboration displayed their data on GLEAMoscope, which shows a multi-wavelength view of the sky at radio wavelengths – at least those that are visible from Australia – from the Murchison Widefield Array. The images are also available as an Android app. Developed by Natasha Hurley-Walker, with input from the Chromoscope team, Gleamoscope even made the New York Times!

Gravitational Waves

The localisations of sources detected by the LIGO detectors are presented on Gravoscope, using the overlay method developed for Planckoscope. Gravoscope is available on GitHub.


The H2O Southern Galactic Plane Survey (HOPS) used Chromoscope to display their data. Chromoscope was cited in Walsh et al. (2011). Unfortunately the HOPS version is no longer available.


This website uses Chromoscope to mad “Diffuse Interstellar Bands” and corrrelate diffuse interstellar bands and correlate with other information, such as interstellar dust, atomic hydrogen and molecules.

Educational Resources

As a simple and effective way to view the sky across the electromagnetic spectrum, Chromoscope has been used by many teachers. It is used in the “Multiwavelength Universe” resource developed by Cardiff University.
