    The Earth’s Seasonal “Heartbeat” as Seen from Space



    We all know that as the seasons change on Earth, temperatures rise and fall, plants grow or die, ice forms or melts away. Perhaps nobody is more aware of this than NASA’s Visible Earth team who provide a vast catalog of images of our home planet as seen from space. Last month designer, cartographer, and dataviz expert John Nelson download a sequence of twelve cloud-free satellite imagery mosaics of Earth, one from each month, and then created a number of vivid animated gifs showing the seasonal changes in vegetation and land ice around the world.

    Despite having encountered numerous seasonal timelapse videos shot here on Earth, this is the first time I’ve ever seen anything like this visualized on such a large scale from space. It really looks like a heartbeat or the action of breathing. Read more over on Nelson’s blog, or see a much larger version of the gif here.

    "A still more glorious dawn awaits
    Not a sunrise, but a galaxy rise
    A morning filled with 400 billion suns
    The rising of the milky way"

    "The sky calls to us
    If we do not destroy ourselves
    We will one day venture to the stars" -Carl Sagan
