      Pixar's Lovable Robot Has Important Lessons For Us

      (Newser) - Yes, Wall-E has environmental themes, but its main point is a moral one, writes Michael Gerson in the Washington Post . Not simply a critique of capitalism, as some conservatives have suggested, the movie sets its satirical sights on our self-imprisoning culture of consumption—and the snacking, reclining consumers in the audience. It offers us an alternative of hope, beauty, and joy. More »

    • Mercury Is Shrinking

      Mercury Is Shrinking

      (Newser) - The planet Mercury is shrinking, the LA Times reports. Data from NASA’s Mercury Messenger spacecraft reveal that the planet’s diameter has shrunk by a mile over its history, probably because its core is cooling. Messenger flew in for a close-up in January, and scientists are now piecing together the new information and re-evaluating some long-held beliefs about the planet. More »

      Earth Hits Cosmic Pitch

      (Newser) - Earth’s atmosphere produces a natural sound and beams it off into the universe, Space.com reports. The sound—a painful series of chirps and whistles—is made by the collision of charged particles from the solar wind with Earth’s magnetic field. More »

      There's a Huge Moon on the Rise

      (Newser) - Northern Hemisphere residents, check out the night sky tomorrow for an extra-large-looking moon. The moon illusion—a trick our brain plays on us—is enhanced by the summer solstice, and when Earth's satellite rises close to the horizon, conditions are perfect, LiveScience notes. More »

      'Incredible' Final Walk for Shuttle Astronauts

      (Newser) - Two shuttle astronauts completed their third and final spacewalk yesterday outside the International Space Station, racking up more than 20 hours floating in space. The pair completed maintenance on the station's cooling system and Japanese lab, taking time out to admire spectacular views, reports Space.com. More »

    • Asteroids Could Reseed a Devastated Earth

      Asteroids Could Reseed a Devastated Earth

      (Newser) - If a comet ever obliterates life on Earth, don't worry—space rocks could later fall in and reseed a few basic life forms. A new study shows that organisms can survive being hit by a meteor, ejected into space, and hurtled back to Earth on the face of a rock—which is good news should we ever go the way of the dinosaurs, Astrobiology reports.

      New Notes in Earth's Hum

      (Newser) - Scientists have discovered a new dimension to the sub-aural sound emanating from our planet’s crust, dubbed “Earth’s hum.” Researchers have known about the hum, detectable only by seismometers, for a decade, though its ultimate cause is unclear. They expected to find hidden oscillations, but the amplitude of the new “ring-like waves” dwarfed expectations, LiveScience reports. More »

      Top 10 Planet Earth Puzzlers

      (Newser) - Forget deep-space exploration; even basic questions about Earth still have scientists scratching their heads, LiveScience reports. A panel of geologists and planetary scientists lists its top lingering mysteries. How did Earth form into such a distinct body? What happened during Earth's first 500 million years? How did life start on this planet? What’s happening inside Earth and how does this affect the surface? More »

      Saturn Moon Rings Detected

      (Newser) - Saturn’s second-largest moon, Rhea, could be the first known moon with rings. The spacecraft Cassini detected apparent evidence of rings when it spotted debris around Rhea as it flew by in 2005, reports space.com. The set of rings has not been directly seen, but scientists inferred that the rings existed because the spacecraft measured a drop in electrons on both sides of the moon. More »

      Take a Peek at Lunar Eclipse

      (Newser) - The sky is putting on a show tonight. The last total eclipse of the moon until 2010 got under way about 8:45pm ET, Space.com reports. The moon went into full eclipse at 10:01, and the show will be over at 12:09. The spectacle should be visible from all points in the US, astronomers say. No special equipment is needed, except maybe some warm clothes. More »

      Want Oil? Try Saturn's Titan

      (Newser) - Titan, one of Saturn's dozens of moons, has supplies of natural gas and liquid hydrocarbons hundreds of times greater than Earth’s oil reserves, Space.com reports. The unmanned Cassini spacecraft has mapped only 20% of Titan’s surface with radar, and has already discovered dozens of bodies of hydrocarbon liquid, each one of which more volume than Earth’s entire oil supply.

    • Earth's Mystery Core Plumbed

      Earth's Mystery Core Plumbed

      (Newser) - Climate change has sparked heated debate about the Earth’s surface, but a controversial new theory is directing scientists to its core, Der Spiegel reports. To explain why contintental plates drift on the surface of the Earth's molten mantle, Maruyama Shigenori, a leading geophysicist, argues that continents actually have life cycles. Old, cold plates on continental fringes sink to “plate graveyards” deep in the Earth’s mantle, and then rise again, creating volcanoes. More »

      Old Spy Satellite Falling to Earth

      (Newser) - A dead US spy satellite will likely tumble out of space and hit Earth late next month or early March, the AP reports. Unnamed officials admitted it may contain toxic material but refused to say where it might land or whether it could be shot from the sky. "We are looking at potential options to mitigate any possible damage this satellite may cause," said a National Security Council rep. More »

      Asteroid to Whiz Past Earth

      (Newser) - A big asteroid is set to speed past Earth on Tuesday night, and those with amateur telescopes will get a peek. NASA discovered the object in October, and scientists believe it's between 500 and 2,000 feet in diameter, LiveScience reports. It won't come closer than 334,000 miles to Earth; the impact of
