    Astronomers have discovered the darkest known exoplanet -- a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on it, making it blacker than coal or any planet or moon in our solar system.

    "its exotic atmosphere contains light-absorbing chemicals like vaporized sodium and potassium, or gaseous titanium oxide." Plus the stuff they don't know yet.

    Arch, do they say what type of sun it revolves around?

    It seems like a good design for footballs at the next world cup, we can name it umm, 'Dark and Deadly' :p
     
  9. I wonder if any Xenomorphs live there. And yes, I mean to capitalize that "X". This planet is probably too hot for anything we've conceived of, but it is nice to imagine.
