Google announced yesterday the release of the new Google Earth Browser Plug-in, which brings the full power of Google Earth to the web, embeddable within your own web site. Driven by an extensive JavaScript API, you can control the camera; create lines, markers, and polygons; import 3D models from the web and overlay them anywhere on the planet. In fact, you can even overlay your content over different planets, stars, and galaxies by toggling Sky mode, letting you build 3D Google Sky mashups. You can also enable 3D buildings with a single line of JavaScript, attach JavaScript callbacks to mouse events, fetch KML data from the web, and more.
