    The Earth-Bashers

    Mars isn't the only planet with awe-inspiring craters. Here on Earth, we've been pummeled by space rocks in the not-so-distant past, and our planet has the scars to prove it. A new photo essay in National Geographic by Stephen Alvarez tells the story of planetary impacts like this one (above) in Arizona, U.S., called simply Meteor Crater. It's almost a mile wide. Check out an even more awesome one below. More »

    The Pale Beauty of a Martian Salt Mine

    Vernor Vinge has said that he drew inspiration for the planet of the Tines from a visit to Norway, and Amy Thomson told me recently that she traveled to Mongolia to get a feel for the planet where her recently-finished novel is set. If the otherworldly photographs George Steinmetz recently took in Bolivia are any indication, this cold, arid, beautiful country could easily inspire a novel about life on a terraformed Mars. Here, in the massive salt flats of Uyuni, you can see the pale piles of mineral that miners have chipped from the ground with pickaxes. A very thin layer of water over the salt creates a reflective surface. More uncanny images below. More »

    Top Ten Most Realistic Planets in Science Fiction

    One of the worst examples of unrealistic science in movies is the overly simple alien planet. Oftentimes, our heroes will visit the desert planet, or the Irish planet. But the best extraterrestrial worlds in science fiction are the ones with variety and a realistic ecosystem. They have cities as well as countryside, and a range of environments. Here's our guide to the most realistic — and interesting — planets in science fiction. More »

    Comet Vs. Comet Around A Dead Star

    A planetary system seems to have survived the death of its star, judging photos released last August from NASA's Spitzer Space Telescope. The Helix Nebula, 700 light years from Earth, is the unraveling remains of a star not unlike our sun. It's also one of the few nebulae to show any evidence of bodies that survived that disaster. More nebula pics, including one that shows battling comets that outlasted the sun's death, after the jump. More »
