It will use the giant Hobby-Eberly Telescope at McDonald Observatory and a set of spectrographs to map the three-dimensional positions of one million galaxies. The companion website features video interviews with the key astronomers leading the investigation, informational podcasts and downloadable audio, and interactive timelines and diagrams to help explain the quest to understand this hidden aspect of nature. http://stardate.org/hetdex/ http://stardate.org/hetdex/ Thu, 8 May 2008 18:04:51 -0500
