  • Earth-like planets may be quite common, relatively close, study says

    Is the Earth a “cosmic freak” or a planetary average Joe around our galactic neighborhood? UC Berkeley astronomer Geoff Marcy says we’re in good company. With some clever sleight of hand, scientists using Kepler data have calculated...
  • Milky Way may host billions of Earth-size planets

    There's no place like home, but scientists now say that Earth-size planets orbiting sun-like stars in a so-called habitable zone are so common that there could be as many as 11 billion in the Milky Way alone. Using a clever method to detect Earth-size...
  • 28 solar flares in the last seven days, and more may be coming

    28 solar flares in the last seven days, and more may be coming
    The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming. This shouldn't be unusual. After all, we are technically at solar maximum,...
  • Don't mourn comet ISON yet: Sun-grazer may well survive, experts say

    Don't mourn comet ISON yet: Sun-grazer may well survive, experts say
    Will comet ISON survive its plunge into the sun's atmosphere or will it perish, like Icarus, for venturing too close? Astronomers say that reports of its looming demise are greatly exaggerated. ISON, known officially as C/2012 S1, is a sun-grazing comet...
  • Kepler-78b: This scorched planet is more like Earth than you think

    Kepler-78b: This scorched planet is more like Earth than you think
    Astronomers have discovered a world that is incredibly close to Earth-sized and may also be made of rock and iron, like our own planet. The only problem? It’s a scorched hellscape of molten lava that sits less than a million miles from its star&...
  • 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...

    A lunar eclipse last Friday? Not so fast ...
    Was that a lunar eclipse last Friday? Not so fast … A Hampton Roads resident thought she saw a lunar eclipse last Friday just after dusk. She told the Daily Press she even pulled off the road and stopped to get a better look. But … was...
  • 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...
  • 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...
