Google Earth Pro (the desktop version of Google Earth) has offered historical imagery for many years. You can access that imagery by selecting the timeslider icon in the menu at the top of Google Earth when it is open on your desktop. Today, Google unveiled some updates to their Google Earth Engine Timelapse website that offers historical imagery in an online version of Google Earth. The timelapses are animations that play 35 years of satellite imagery. In the following video I demonstrate how to access the timelapses and the historical imagery in Google Earth.

Applications for Education
The timelapse and historical imagery could be useful in a science class to help students see how coastlines and other features of landscapes change over time.
