  • Water on Earth predates the solar system, and even the sun

    Water on Earth predates the solar system, and even the sun
    Some of the water molecules in your drinking glass were created more than 4.5 billion years ago, according to new research. That makes them older than the Earth, older than the solar system — even older than the sun itself. In a study...
  • Fall starts Monday? Sez who?

    Monday is the first day of autumn. This is according to the chart of astronomical seasons and the little calendar here at my desk. Sept. 22, astronomers believe, is the first day of the fall season this year. Astronomers also believe, ridiculously, that...
  • Water vapor detected in clear skies on Neptune-sized exoplanet

    Water vapor detected in clear skies on Neptune-sized exoplanet
    Eureka! Astronomers say they’ve discovered clear skies and water vapor on a Neptune-sized exoplanet named HAT-P-11b -- which, at roughly four times the Earth's radius, is the smallest planet yet known to host water in its atmosphere. The...
  • Astronomers find gigantic black hole -- in a teeny tiny galaxy

    Astronomers find gigantic black hole -- in a teeny tiny galaxy
    Sometimes big surprises come wrapped in tiny galactic packages. That’s the strange find from a team of astronomers who discovered an enormous supermassive black hole in a very unlikely place: at the center of an ultracompact dwarf galaxy. The...
  • Northern lights sightings possible in Chicago Friday

    The northern lights might be coming to Chicago tonight and they're not playing at Riot Fest.  A large "coronal mass ejection"—the technical term for a bunch of charged photons from the sun jetting toward earth—that occured Wednesday will hit...
  • Boynton artist selected for 63rd annual All Florida Exhibition

    Since relocating to Boynton Beach this year from Lexington, Ky., to begin her new position as assistant professor of art at Florida Atlantic University, Sharon Lee Hart has become fascinated by the sea. "Not as in fun in the sun," the photographer is...
  • At last! Cassini spies methane clouds on Saturn's moon Titan

    At last! Cassini spies methane clouds on Saturn's moon Titan
    Flying past Saturn’s moon Titan, NASA’s Cassini spacecraft has caught a few glimpses of methane clouds speeding over the enormous moon’s hydrocarbon seas in its northern polar region. Clouds developed and dissipated over Ligeia Mare, a...
  • Specks of star dust likely first from beyond solar system

    A NASA spacecraft dispatched 15 years ago to collect samples from a comet also snared what scientists suspect are the first dust specks from interstellar space. The Stardust robotic spacecraft was launched in 1999 to fly by a comet and collect samples...
  • Scientists think they have dust specks from outside our solar system

    Scientists think they have dust specks from outside our solar system
    Call them the seven wonders of interstellar space: Tiny specks of dust captured by a NASA spacecraft may be the first material from outside the solar system ever caught and brought to Earth. Researchers studying the contents of a capsule returned to...
  • See the supermoon at Mammoth Mountain

    For the first time, Mammoth Mountain will host a Supermoon Viewing Party on Saturday from 6 to 10:30 p.m. Guests can take an evening gondola ride to the summit and enjoy live music, food and drink and one of nature's most spectacular scenes. The cost is...
  • NASA's flying saucer takes a supersonic flight, and you can tag along

    NASA's flying saucer takes a supersonic flight, and you can tag along
    By the time NASA’s flying saucer splashed down in the Pacific in June, the engineers who designed it already knew their experiment had been a huge success. From the control tower at Kauai’s Pacific Missile Range Facility, they had watched...
