Description
A system of seven Earth-sized planets has been observed orbiting a (relatively) nearby star. At least three of these planets are in the habitable zone, or as Top Astroquark Jim Cooney would say, the haBITable zone. That's where there may be liquid water on the surface of the planet. The star for these planets is tiny and not so hot, so the planets are huddled around it like campers around the embers of a dying fire. Tune it for that plus: Star Wars! Note to Star Wars and Star Trek: next movie have some planets that are, like these, so close to their star that they have synchronous rotation, with a permanent dayside and a permanent nightside!

Fear and Loathing
If you're taking a walkabout the galaxy, you're going to run into black holes, pulsars, asteroids. I'm hearing a lot of things about black holes. They're hiding in the shadows, they're sucking up all our matter, all our light. And let me tell you something, asteroids are coming, they're coming, folks. Take a look around you, they have minerals, they have metals, I'm hearing that they may have water. And when they come, it's not going to be pretty, I can tell you that. You should be very afraid of the asteroids. And don't get me started on the comets. Have you seen these things? You call those tails? That's not what I call a tail, I'm just saying.
