NASA creates ultimate time-lapse of life on Earth


THIS wonderful NASA map of earth from multiple satellites shows climate change has altered the face of our planet in the past 20 years.

NASA has been continuously monitoring physical properties of Earth from space since 1997.

Programmer Alex Kekesi of NASA's Goddard Space Flight Center in Maryland said it took three months to complete the visualisation, using satellite imagery. The specific satellite used for the timelapse, called the Sea-Viewing Wide Field-of-view Sensor, was launched in 1997, allowing for 20 years of space-view footage. "That's the Earth, that is it breathing every single day, changing with the seasons, responding to the Sun, to the changing winds, ocean currents and temperatures".

You can see the changes in the video above. Thanks to the data, scientists are able to monitor forests, crops, fisheries and more around the world. These observations not only provide a much clearer picture of Earth physical features but they can also help address questions about the impact of global warming and the response of local ecosystems to a changing climate.

The two and a half minute data visualisation released by Nasa covers a period starting from September that year up to this past September 2017.

In a tweet shared by the aeronautic giant, where in they posted a.GIF with the caption, "We're going to have a great view of the state of the biosphere on our planet", it can be seen how over the period the portions under ice has increased (or at least that is what it looks like)".

Employee of the jet propulsion laboratory of NASA renyu Hu said that on one of the exoplanets in the star system 55 Cancer can be the atmosphere, its composition and characteristics similar to earth. "And we watched it happen in real time", said Feldman. Meanwhile, the changing colours of the ocean show undersea life thriving - or dying.
