In a few days -- barring cloud cover -- the night skies will present one of the more arresting displays of meteors streaking through space. Known as the Lyrids, the shower of light has appeared in mid-April for about 2,600 years. When the meteors peak before dawn April 22, as many as 100 of them an hour will arc across the sky. Anticipation for the showers was heightened last week after a shooting star lighted up the sky with an impressive bright green light. "I've seen pretty bright meteors ... but nothing like this one," said astronomer Dan Joyce, 64. Of the increased interest in the Lyrids after the impressive meteor shower, Joyce said: "That would be a big plus. Not enough people look at the sky."
CHICAGO TRIBUNEPhew! Killer asteroids aren't in your future If you're worried about a killer asteroid wiping out Earth, NASA has some good news. The space agency said Thursday that it has identified more than 90 percent of giant, potentially Earth-threatening asteroids, including some as big as the one thought to have killed the dinosaurs. "We know now where most of them are and where most of them are going. That really has reduced our risk." Photo: Wide-field Infrared Survey Explorer, which is tracking huge asteroids
