A flurry of announcements last week related to Silverlight, Microsoft’s rich media browser plugin. Some will be of interest largely to geospatial professionals or web developers, like the public beta of the ArcGIS API for Silverlight or the Virtual Earth Silverlight Map Control.

Me, I’m delighted to see that Microsoft has ported WorldWide Telescope to Silverlight, making it available in a Web client — which means that, as a Mac user, since Silverlight is cross-platform, I can finally have a look at WorldWide Telescope!
