# Multi-Wavelength, Multi-Platform, Multi-Device, Multi-Screen  Today, amateur astronomers are blessed with a wealth of so-called  "planetarium" programs software  to choose from and some program runs on nearly any device. Like much of the other software available for free or at low cost to amateurs, WorldWide Telescope is an astrometrically correct 3D model of the Universe populated by the highest resolution imagery from ground and space based telescopes. But, WWT's imagery is unique in its quality, and in its ability to show the sky at 85 different wavelengths, most of which are beyond the spectral window of the human eye. WWT features a seamless visible light view (based on imaging from the Palomar Digitized Sky Survey) of the night sky that is a _trillion_ pixels in size, allowing users to zoom from a 60-degree wide field view of the Milky Way to a close up view of features as tiny as the wisps of the Veil nebula. WWT also has 85 different multispectral sky views that are all precisely registered to allow for cross fading between them.
