Gotcha'

I figured it was going to happen soon, but not this soon: astronomers have discovered an earth-like planet outside our solar system, in orbit of the red dwarf Gliese 581, only 20.5 light-years away (that's actually pretty close). The planet, 581 c, is about five times heavier than Earth and may have liquid water on it surface. Suh-weet.

Also, astronomers have picked up on a interesting connection between two cycles: the extinctions on Earth, and the Earth's journey through the galactic plane of the Milky Way. Both occur every 64 millions years or so. Hmm.
