The beauty of the Earth from space: Incredible Nasa animation shows how forest fires scar the land and rivers give it new life

  • Nasa collected the data using satellites and infra-red imaging technology that orbits 512 miles above the Earth
  • A computer program was used to find cloudless areas so the image wasn’t obscured
  • The data will be used to help with environmental monitoring, predicting global changes in the weather and tracking the damage caused by drought

A year’s worth of changes to vegetation across the world have been plotted during a fascinating animation by Nasa.

The space agency spent a year collecting satellite images using its Suomi National Polar-orbiting Partnership technology and the photos provide a vivid, at-a-glance depiction of the Earth’s natural landscape.

They highlight the stark contrast between the plush green lands of Europe next to the dry, arid regions of Africa. The images also show how forest fires can physically scar the landscape in places such as Australia and how rivers, in dry areas such as Egypt, can replenish the land and provide a life source for its inhabitants.
