Begun in 2007 as a research project led from within Microsoft Research with collaboration from astronomers and educators from Caltech, Harvard, Johns Hopkins, Northwestern, the University of Chicago, and several NASA facilities, WWT has reached its goal of creating a free unified contextual visualization of the Universe with global reach that lets users explore multispectral imagery, all of which is deeply connected to scholarly publications and online research databases.
