Google Earth Virtual Tourism Layer
Google Earth 4.3 was released two days ago. The new release includes lots of new features like street view and night and day lighting effects.
More importantly there is now also a Virtual Tourism layer.
The layer is available in the Sky section of Google Earth in the Education Center folder. The layer is more or less what you can see in our Star Viewer map.
The Google Earth layer does not have quite as many videos as our Star Viewer map because the Hubblecast videos have been removed. Hubblecast also now have their own layer in Google Earth so to have included them in the Virtual Tourism layer would have led to unnecessary replication.
