  • Meet Kepler-186f, the most 'Earth-like' planet ever found

    Meet Kepler-186f, the most 'Earth-like' planet ever found
    Sifting through observations from tens of thousands of distant stars, astronomers say they have discovered the first definitive Earth-sized planet that orbits in a habitable zone where water could exist in liquid form — a necessary condition for...
  • Earth-sized planet found orbiting in a habitable zone

    Sifting through observations from more than 100,000 distant stars, astronomers say they have discovered the first definitive Earth-sized planet that orbits in a habitable zone where water could exist in liquid form — a necessary condition for life...
  • Suburban teachers picked for NASA astronomy program

    Suburban teachers picked for NASA astronomy program
    A high school science teacher from Mundelein and a retired teacher from Long Grove were chosen by NASA to become airborne astronomy ambassadors for a program in California this spring. In a few months, Marcella Linahan, a science teacher at Carmel...
  • Concern grows over possibility of a massive power surge

     Concern grows over possibility of a massive power surge
    FREDERICK, Md. — Roscoe Bartlett was rattling off the prices of giant bags of rice, wheat and corn, sold cheaply at Sam's Club. The former congressman from rural, western Maryland expressed bewilderment that every American doesn't stockpile such...
  • Trailing Christopher Columbus and a total eclipse in the Atlantic

    Trailing Christopher Columbus and a total eclipse in the Atlantic
    MÁLAGA, Spain — When I was 8 years old, I wanted to run away to sea and be a cabin boy on a clipper ship. Sixty years later — gender, age and vocation notwithstanding — I finally got the chance. As I packed to meet the Star Flyer on...
  • 2014 stargazing calendar: Catch three eclipses, new meteor shower

    2014 stargazing calendar: Catch three eclipses, new meteor shower
    Unique celestial events in 2014 include two full lunar eclipses visible from Maryland and a partial solar eclipse that will begin just before sunset one October afternoon. A new meteor shower could be a bonus. Here’s what stargazers have to look...
  • Hubble Space Telescope finds clouds on super-Earth, Neptune-sized planets

    Hubble Space Telescope finds clouds on super-Earth, Neptune-sized planets
    Using NASA’s Hubble Space Telescope, two research teams have discovered thick layers of high-altitude clouds covering the atmospheres of two relatively nearby exoplanets: a super-Earth and a "warm Neptune." Scientists are beginning to get a handle...
  • Supernova dust factory seen at last; may explain early galaxy formation

    Supernova dust factory seen at last; may explain early galaxy formation
    Using a powerful radio telescope, scientists have spotted an enormous cloud of dust billowing in the center of a supernova - finally. The discovery, announced at the American Astronomical Society, helps to confirm what scientists have long thought -...
  • Bright ancient galaxies offer rare glimpse of early universe

    A quartet of galaxies spied with NASA's Hubble Space Telescope are among the oldest yet discovered — more than 13 billion years old, born just 500 million years after the big bang. They're also incredibly bright, so luminous that they offer a new...
  • Hubble harnesses gravity to find dim, ancient galaxies near big bang

    Hubble harnesses gravity to find dim, ancient galaxies near big bang
    If you’re a giant space telescope squinting into the far reaches of the cosmos, gravity is your best friend. Using the magnifying powers of massive galaxy clusters, three of NASA’s Great Observatories – the Hubble, Spitzer and Chandra...
  • Northern lights may make rare appearance in parts of U.S.

    A solar storm may cast colored lights – known as the Aurora Borealis or Northern lights – in the sky over parts of the northern Plains, the Great Lakes region and Northeast on Thursday and Friday, forecasters say. “It’s a very...
