  • 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...
  • Mystery object in Saturn's ring may be a new baby moon: Peggy

    Mystery object in Saturn's ring may be a new baby moon: Peggy
    The moons that orbit Saturn may be increasing by one -- an icy, pint-sized object that astronomers have named “Peggy.” NASA’s Cassini spacecraft has spotted evidence that a mysterious object measuring perhaps half a mile across is...
  • In a first, scientists find an asteroid with rings

    In a first, scientists find an asteroid with rings
    In a first, scientists have detected rings encircling an M&M-shaped asteroid known as Chariklo. Until now, only the solar system's four gas planets — Jupiter, Neptune, Uranus and especially Saturn — were known to have rings. "It was an...
  • NASA would get $17.5 billion for 2015 under White House budget plan

    NASA would get $17.5 billion for 2015 under White House budget plan
    NASA’s budget for the 2015 fiscal year wouldn’t budge much from last year under the White House’s proposal for nearly $17.5 billion, as officials reaffirmed the commitment to extending the life of the International Space Station, funding...
  • Schiff says planetary science funding insufficient

    Schiff says planetary science funding insufficient
    Earlier this month, President Barack Obama released his $3.9 trillion budget proposal for fiscal year 2015. The plan sets aside $1.28 billion for planetary exploration — an amount one elected official is calling a far cry from what will be...

    Explore the site of one of the moon's newest impact craters -- live
    ) The largest lunar impact ever caught on camera took place last Sept. 11, when a small asteroid 2 to 4.5 feet in length slammed into our moon's pockmarked surface at 37,900 mph. The resulting explosion caused a flash of light that briefly burned as...

     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...
  • Weird wobbly planet? Kepler-413b may have speedy seasons

    Weird wobbly planet? Kepler-413b may have speedy seasons
    Imagine a planet that wobbles so wildly that its seasons are constantly shifting and its constellations speed across the sky. Astronomers using data from the planet-hunting Kepler Space Telescope have found just such a weird world, twirling like a top...
  • Asteroid the length of 3 football fields eludes sky-watchers

    Asteroid the length of 3 football fields eludes sky-watchers
    An asteroid the length of three football fields has eluded astronomers once again. "If we see it, that will be historic because we've reacquired a potentially hazardous asteroid," astronomer Bob Berman said Monday night. "If it turns out we can't see...
  • Watch: X-rays from a star's corpse reveal supernova secrets

    Watch: X-rays from a star's corpse reveal supernova secrets
    Staring into the dramatic corpse of a dead star known as Cassiopeia A, astronomers using NASA's NuSTAR X-ray telescope have for the first time mapped out radioactive titanium in a supernova. Charting this astrophysical frontier, as described in the...
  • Kepler's comeback? New K2 mission could chase wilder targets

    Kepler's comeback? New K2 mission could chase wilder targets
    Don't call it a comeback just yet. Astronomers mourned the Kepler Space Telescope after it was crippled last year. But NASA’s planet hunter may be getting a second chance at life — with an ingenious, just-so-crazy-it-might-work plan that would...
