Planetarium-Friendly Versions of Planck All-Sky Maps Available

Planck is a space observatory of the European Space Agency (ESA) designed to observe the anisotropies of the cosmic microwave background over the entire sky. Planck's all sky maps showing the oldest light in our universe, as well as the calculated distribution of mass of the universe, are now available in a format suitable for use in planetarium systems and other 3D software. These maps are in an equirectangular projection suitable for projection onto a sphere, useful for full-dome presentations. The projection is in galactic coordinates with the galactic plane running horizontally along the midpoint of the image. Note that most generic 3D graphics software will map images to the outside of a sphere; since this is the inside projection looking outwards the image should be flipped horizontally when used with such software to create a sky dome to be viewed from the inside.

Both datasets are also available as layered Photoshop-compatible TIFF files. These include the sky maps in greyscale, allowing users to assign their own color maps. The mass map also includes a separate layer for the foreground mask.
