Earth's Seasonal Heartbeat

Combine a dozen crystal clear satellite mosaic images of Earth, one from each month over the course of a year, and turn them into an animated GIF. What would you see? If your angle of view was directly over the north pole, you’d see the seasonal changes of vegetation and ice as they advance and recede, and they would appear to pulsate—like a heartbeat. It’s a pretty remarkable image made by designer/cartographer/data-visualizer John Nelson of NASA’s Visible Earth team. It’s the kind of thing that we never would have seen a decade ago, reminding me yet again what an amazing era of images in which we’re living.
