    Deep network

    Gas bubbles effervesce from a mound of muck on the seafloor in a deep submarine canyon off the west coast of Canada. Microbes beneath the sediment belch the bubbles after feasting on the ancient remains of algae, sea critters and their poop: a primordial stew that’s been simmering since long before humans walked the Earth.

    This gassy oasis attracts an odd collection of critters. Worms...

    Images from the Edge

    David Schiminovich stared at a gallery of spiral galaxies as though he had never seen anything like them before. Indeed, no one had. He sat downloading the newly collected images in a narrow room overlooking a cavernous space at the California Institute of Technology in Pasadena.

    Infrasonic Symphony

    "Let me start off with a riddle," says NASA scientist Allan J. Zuckerwar. In his office in Hampton, Va., he rattles off items as dissimilar as rhinoceroses, supersonic aircraft, and hurricanes. "Now, what do they have in common?" The answer, Zuckerwar explains, is that each one generates silent infrasound—long sound waves at a frequency below 20 hertz. People can't hear anything below that...
