    The Improbability Principle

    Incredible things happen routinely. People win the lottery — twice. Golfers hit holes-in-one several days in a row. Basketball players appear to get a “hot hand” (SN: 2/12/11, p. 26; SN Online: 10/29/13).

    Do these chance events validate superstition or suggest a hidden influence in our world — a higher power, perhaps? Absolutely not, argues Imperial College London...

    See the sky in a different light

    Gazing at the vast sky on a dark, clear night is humbling. But what if your eyes could see infrared light? The view might look something like NASA’s new interactive map of the galaxy. GLIMPSE360 is a night-sky atlas assembled from over 2 million images taken by the Spitzer Space Telescope.

    Because interstellar clouds block visible light, the infrared maps allow you to peer through...

    Narwhal has the strangest tooth in the sea

    View slideshow

    Sometimes called the unicorn of the sea, the male narwhal’s tusk is actually a tooth, and it grows directly through the whale’s upper lip instead of pushing the lip aside. It’s an exuberantly large version of a canine tooth that grows in a spiral; the only tooth known to do so. Otherwise narwhals are practically toothless, with only vestigial stubs that stop growing during...

    Gravity’s Ghost and Big Dog

    Roughly 50 kilometers east of Baton Rouge, La., lasers ricochet off mirrors that dangle at the ends of a 4-kilometer-long, L-shaped vacuum tube. A nearly identical facility sits almost 3,000 kilometers away in Washington state. The research stations — part of the Laser Interferometer Gravitational-Wave Observatory, or LIGO — are designed to sense gravitational waves, minuscule...

    Illuminating a dark universe

    A hundred years ago, astronomers knew of just one galaxy: our own. Today they know the universe hosts billions. What’s more, the visible stuff of galaxies is dwarfed by dark matter, and each galaxy is racing away from the others due to an even more mysterious entity: dark energy. Dark Universe, developed by the American Museum of Natural History’s Hayden Planetarium in New York City,...
