Dinosaur-killing impact set Earth to broil, not burn - 0 views

  •  
    The asteroid impact that ended the age of dinosaurs 65 million years ago didn't incinerate life on our planet's surface - it just broiled it, a new study suggests. The work resolves nagging questions about a theory that the impact triggered deadly wildfires around the world, but it also raises new questions about just what led to the mass extinction at the end of the Cretaceous period.

NASA - The Impact and Recovery of Asteroid 2008 TC3 - 0 views

  •  
    The Impact and Recovery of Asteroid 2008 TC3.\nNASA detects and tracks asteroids and comets passing close to Earth. The Near-Earth Object Observation Program, commonly called "Spaceguard," discovers, characterizes and computes trajectories for these objects to determine if any could be potentially hazardous to our planet. \n\n

Renewed Challenge to the Dinosaur Killer - 0 views

  •  
    Gerta Keller (Princeton University) and Thierry Adatte (University of Lausanne) believe the Chicxulub crater in northern Yucatan was formed some 300,000 years before the mass extinction occurred. Moreover, Keller argues in the upcoming Journal of the Geological Society that not a single species went extinct as a result of the impact.

Small Asteroid 2009 VA Whizzes By The Earth - 0 views

  •  
    A newly discovered asteroid designated 2009 VA, which is only about 7 meters in size, passed about 2 Earth radii (14,000 km) from the Earth's surface Nov. 6 at around 16:30 EST. This is the third-closest known (non-impacting) Earth approach on record for a cataloged asteroid.
