The Earth may have survived its close encounters with an asteroid and a meteor Friday, but the episodes focused new attention on gaps in astronomers' ability to identify smaller space rocks like these capable of inflicting widespread destruction.

A meteor streaked across the sky and exploded over Russia's Ural Mountains with the power of an atomic bomb Friday, its sonic blasts shattering countless windows and injuring nearly 1,000 people. The spectacle deeply frightened many Russians, with some elderly women declaring that the world was coming to an end.

A sonic boom heard in California last week had an out-of-this world origin as ”a large meteoric event” according to NASA’s Meteoroid Environment Office. Scientists now estimate the blast measured in near 5 kilotons or roughly 1/3 the power of the atomic bomb dropped on Hiroshima, Japan during World War II. Bill Cooke of the Meteoroid Environment Office at NASA’s Marshall Space Flight Center, estimates the object was about the size of a minivan, weighed in at around 154,300 pounds.

Scientists are confirming a recent and rare invasion from Mars: meteorite chunks from the red planet that fell in Morocco last July. This is only the fifth time scientists have chemically confirmed Martian meteorites that people witnessed falling. The small rock refugees were seen in a fireball in the sky six months ago, but they weren't discovered on the ground in North Africa until the end of December.

The night sky will put on a show in the coming days – and you don't need a telescope to appreciate it, according to University of Virginia astronomer Ed Murphy. The annual Perseid Meteor Shower, which typically produces 50 to 60 ...
