NASA has captured 20 years of seasonal changes in a striking new global map of the home planet.
The data visualization, released this week, shows two decades’ worth of Earth’s biosphere.
Several satellites were used between September 1997 and September of this year, to compile the data. The polar ice caps can be seen expanding and shrinking with the alternating seasons. In addition, the varying shades of blue, green, red and purple in the oceans depict the abundance _ or lack thereof _ of undersea life.
Programmer Alex Kekesi of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, says it took three months to compile the visualization. He says it will be updated over time, as computer systems for combining numerous data sets like this improve.

NASA video shows Earth ‘breathing’ as seasons cycle, climate changes
US space agency NASA has compiled the most complete picture of life on Earth. Scientists used imagery from satellites that circle the planet 14 times every day to create a timelapse that some say shows the planet “breathing” as the seasons cycle and climate changes. Compton Tucker, the top Earth Scientist at NASA, discusses with CGTN’s Asieh Namdar.
