The people at NASA don’t always have their heads above the clouds, looking outwards. They just as often use their incredible technology and expertise to get a bit introspective and gaze down onto Earth.
Using data received from numerous satellites, this incredible animation shows the 12-month cycle of Earth’s seasons. As well as showing the vegetative plant life on land, it also shows the chlorophyll concentration from microscopic organisms called phytoplankton in the ocean.
The parts where the land looks brown and barren are regions of Earth experiencing their winter months, whereas during summer you'll see a lush green.
Enjoy.
