Knock, knock. It's humanity.

If you follow space news at all, you're probably aware that humanity has a doohickey called the Rosetta probe orbiting a comet, specifically comet 67P/Churyumov–Gerasimenko, or "67 Pikachu" for short (not really, I made that up). This was a pretty big deal, since people don't put space probes into orbit around a comet every day...or ever, since it was our first time. Even more groundbreaking, we shot an even smaller doohickey—the Philae lander—onto the comet's surface.

In space, no one can hear comets burp. (via ESA)
