*This is no joke. If you’ve ever thought about saving the planet, this may be the job for you! According to reports, NASA is taking applications for its ‘Planetary Protection Officer’ position. There’s just one small catch: Whoever gets the job is expected to save life on planet earth (and planets everywhere else) from extraterrestrials.

More than two millennia ago, the philosopher Anaxagoras was the first to publish on panspermia, but it’s current interest goes back only a century or so, to experiments by the Swedish chemist Svante Arrhenius, who theorized that microorganisms might be moved from one planet to another by the radiation pressure of stars.
I almost flunked out of engineering school in college, so all of this is a bit over my head, but stay with me. Continue reading →
