NASA scientists have released a stunning time-lapse video showing our planet's eastern hemisphere from January 18th to July 25th, 2014. Viewed from this perspective, the Earth is seen as a shimmering, swirling orb of hyperactivity.
Looking at the time-lapse, titled "Blue Marble, Eastern Hemisphere," you can see subtle changes in the snow and vegetation cover on the land. The quick-changing cloud cover zips around at a frenetic pace.
"After having the privilege of flying shuttle missions and seeing Earth from the vantage point of space, I'll never forget observing our fragile planet from above with no visible political borders, only those established by the oceans and mountains and other geography," noted NASA Administrator Charles Bolden in a statement. "It's a reminder that our planet belongs to everyone, and we each have a responsibility to help protect it. For NASA, that means making Earth science a priority investment. It's one of the cornerstones of our work."
The composite image was compiled from eight orbits of the Suomi NPP satellite and 10 imaging channels which were stitched together to blend the edges of each satellite pass.
