  • Did two planets around nearby star collide? Toxic gas holds hints

    Did two planets around nearby star collide? Toxic gas holds hints
    In a young, nearby solar system, scientists have discovered giant clouds of poison gas -- the smoking gun from a violent encounter, astronomers say. Based on massive amounts of carbon monoxide gas around the star Beta Pictoris, either two Mars-sized...

    'Cosmos' recap: Starts with a big bang
    Science geeks whipped themselves into a veritable frenzy of anticipation over the weekend for the premiere of "Cosmos," the much-touted reboot of the classic series created by astronomer Carl Sagan in the 1970s. You have to understand: Sagan and his...
  • 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

    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...
  • Video: Watch this space rock crash and flash on the moon's surface

    Video: Watch this space rock crash and flash on the moon's surface
    For a brief moment last September, a flash on the moon shone about as bright as the North Star, Polaris,  giving away the biggest crash from a space rock hitting the lunar surface ever caught on camera, astronomers say. The discovery -- "the brightest...
  • 'Magic Island' may show Titan's oceans are hardly pacific

    'Magic Island' may show Titan's oceans are hardly pacific
    The sudden disappearance of a bright spot on a methane sea on Titan could add more proof that Saturn’s largest moon is a lot like Earth – just colder and gasier. Astronomers at Cornell University were flipping between radar images of...
  • Hopkins scientists pursue origins of the universe

    Hopkins scientists pursue origins of the universe
    Johns Hopkins University scientists are building a telescope meant to look at space in a way no one has before, hoping to probe the blackness between planets, stars and galaxies, into deep time and the mystery of how it all began. For decades,...
  • Solar flares expected to 'shockwave' Earth today

    Solar flares expected to 'shockwave' Earth today
    Feelin’ the heat? Three massive solar flares could “shockwave” Earth today. That’s the upshot from NASA and NOAA, after powerful plasma ejections erupted from the sun earlier this week. The flares pose no danger to humans,...

    Teens launch balloons to edge of space, and so the adventure begins
    High in the Eastern Sierra, a pack of huskies is howling in the shadow of snow-covered peaks. Drawn by their song, 10 teenage members of the Earth to Sky Calculus club break from their work and gather on a cabin deck. Before long, they're howling too....

    Hubble peers deep into the universe, reveals teenage galaxies
    Astronomers using the Hubble Space Telescope have released one of the most comprehensive images of the universe ever taken, and it is awesome. The image you see below is not wide, but it is so deep that it stretches back to just a few hundred million...
  • Two ancient worlds found just 13 light-years from Earth

    Two ancient worlds found just 13 light-years from Earth
    Scientists have discovered two ancient planets orbiting a strange old star right in our stellar backyard. One of the newly found planets is perhaps five times the mass of Earth, and astronomers believe it is the right distance from the host star to...
