Texas-size asteroids make for exciting summer blockbusters, but when
it comes to long-term damage, they're not the most menacing threat
out there. Lurking at the edge of our galaxy are giant molecular dust
clouds -- agglomerations of hydrogen gas, small organic molecules and
minerals -- roughly 150 light-years across. If our solar system hit
one, it would take 100,000 years to pop out on the other side.
