Microsoft has added a WorldWide Telescope application to Bing Maps. The new application allows users of Bing Maps to view real time information about the night sky.
The application allows users to seamlessly switch from Streetside View to a view of the night sky just by panning the Streetside View to look at the sky.
When you click the “Start Here” button you can drag the telescope mouse pointer to any location on the map. You will then be shown a view of the night sky and the stars overhead as it looks right now (if dark).
The WorldWide Telescope application also allows you to query any point of the night sky to identify what is there. To query the map click on the question make and then drag the circle icon to any location on the map.
