Since the 1970’s, earth observation satellites have greatly advanced our understanding in science. Google Earth is a free program that allows users to explore the Earth. It is able to access satellite imagery, elevation data, ocean bathymetry (underwater topography) and other geographic information. It can be used online in google chrome or it can be downloaded on your computer (Windows, Mac or Linux).

You can use the program as a virtual time machine and browse through historical imagery. You can witness the growth of cities, deforestation and impacts of climate change. You can watch glaciers disappear, witness the Aral Sea drying up in Central Asia or observe the disintegration of the Larsen ice shelf in Antarctica. Simply zoom to your region of interest and click on ‘show historical imagery’.
