GoogleWatch writes "Google's all excited for Earth day, and just in time there's a new version of Google Earth available. 4.3 offers up revamped navigation controls, 3-D photo-realistic buildings in major cities, and time-lapse views of sunsets and sunrises. Also new in Google Earth 4.3 is access to the street view movies found in Google Maps. Just click any of the camera icons and the familiar street view window will pop up. The sunrise and sunset movies are also quite impressive. Fly to a location you'd like to see and click the "sun" button in the toolbar. That will bring up a small timeline graphic and you can either hit play or drag the timeline slider to watch the day unfold."
