Chromoscope is an accessible, easy tool that anyone can use to explore and understand the sky at multiple wavelengths.
View the Universe
Chromoscope has been created using public-domain datasets from a number of all-sky astronomy projects. It lets you easily move around the sky and fade between wavelengths using a simple user-interface to illustrate the similarities and differences between what is visible at each wavelength.
There are currently seven included: gamma ray (Fermi), X-ray (ROSAT), H-alpha (WHAM), optical (DSS), infrared (IRAS), microwave (WMAP) and radio (Haslam). You can click on the credit information, shown at the bottom-right of the Chromoscope screen, to learn more about each survey.
Control the sky
To move the map around, simply ‘grab’ it with the cursor and drag around the screen. You can double-click (or use the plus and minus keys on your keyboard or a scroll wheel) to zoom in and out. A simple slider (or a set of keyboard shortcuts) allows you to fade gradually along the spectrum and to see structures and features change as they go. A set of labels can be toggled on and off (with the ‘L’ key) to guide people around the sky and, if an Internet connection is present, users can search for named objects and jump right to them. No installation needed
A standard, modern, web browser is all that you need to use Chromoscope so there is no need to install any extra software, plugins or learn a new interface. Being platform independent means that whether you use Windows, Mac or Linux, it should still be accessible.
