Our ever changing earth.

As mentioned in the video below, green is the colour of life. However, this colour isn't always a constant, with plants dying and being reborn with each change in the season. Whilst this is easy enough to say, new technology has allowed us to visualize this process like never before. A new instrument on the NASA-NOAA Suomi satellite has spent the last year capturing the changing levels in plant cover. 

This was done through measuring the different levels of visible light that was reflected back towards to satellite, which would be absorbed by higher levels of plants, and infrared light which plants reflect. This technology, whilst producing something that could be considered visually stunning, could also act as an early warning system for a number of global events. Watch the video below to see the end result.
