    The Hunt for Antihelium

    Scientists have been searching about 30 years for a single nucleus of helium made from antimatter, and although the discovery would imply that whole antimatter galaxies exist, the researchers' time could be running out.

    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.
