    Exploring Time

    This new educational site offers time-lapse and high-speed video clips, 3D scientific animations, and other visually stunning features that reveal how events unfold on different timescales—from billionths of seconds to billions of years—and take place too quickly or too slowly for the human senses to perceive.
