While Google continues to pull ahead with a healthy share of planetary images, Microsoft announced this week that they signed a deal that gives them access to 100TB worth of NASA’s images, that will ultimately find their way onto the WorldWide Telescope website.

Microsoft has announced that they plan on working with NASA in order to develop “the technology and infrastructure necessary to make the most interesting NASA content.” The content, which will be available on Microsoft’s virtual telescope for exploring the universe, WorldWide Telescope, should be available later this year.

And, for those keeping tabs on just how big 100TB of data is, that’s enough to fill 20,000 DVDs.
