At least Michael Bay won't be directing...

In the year 2182 -- 172 years time -- there's a 1 in 1000 chance that we might be hit by a very large asteroid. With two centuries advance notice, will we be able to develop effective asteroid deflection techniques? [more inside]

Bad news for the Martian dinosaurs...

There's a slight chance that an asteroid could impact Mars at the end of this month. Usually, collisions between heavenly bodies have vanishingly small odds (a million to one, say), but the chances on this one have been steadily improving, from 350-to-1 to 75-to-1 to 25-to-1 (link to Washington Post). Scientists say that this could be comprable to the famous Tunguska blast in Siberia a hundred years ago (not to be confused with this other Tunguska blast). [more inside]

There can be no escape. . .

NASA's Chandra X-Ray Observatory recently detected [reg required] the largest explosion ever detected in the universe: an eruption releasing the energy of hundreds of millions of gamma ray bursts. Just to put it in perspective, a single GRB releases enough radiation to wipe out just about everything human beings would require for survival in a 1000 light year radius. (The Milky Way spans ~100,000 light years, while the United Federation of Planets spans about 8,000). Arthur C. Clarke has gone so far as suggesting that GRBs might be one of the reasons for Extra-Terrestrial silence: Gamma Ray Bursts are so large and inescapable, a single one would wipe out even an enormous galactic empire. Makes killer asteroids seem downright quaint.
