We are all in the gutter, but some of us are looking at the stars.

Comet rain took life's to Jupiter's moons
Dust made from pulverised comets may have seeded Jupiter's moons with the raw ingredients for life. That includes Europa, which is thought to harbour a liquid ocean beneath its icy crust.
Jupiter has two kinds of natural satellites: large spherical moons and smaller lumpy bodies that follow elongated orbits. Chemical analysis of the irregular bodies suggests they are made of the same stuff as asteroids and comets. This means they are probably rich in the carbon-containing compounds that are key to life on Earth.
"Space is big. Really big. You just won't believe how vastly, hugely, mind-boggingly big it is. I mean, you may think it's a long way down the street to the chemist, but that's just peanuts to space." - The Hitch-Hikers Guide to the Galaxy - Douglas Adams 1952 - 2001
