http://www.msnbc.msn.com/id/12837988/ As described in the upcoming issue of Nature, scientists have recently discovered what appears to be a habitable planetary system with 3 Neptune-sized planets surrounding a single star. The two innermost planets are close enough to the sun-like star to resemble Mercury's rocky, hot terrain, while the outermost planet is within range of liquid water formation.
Except for that giant gas cloud surrounding it.
So we can at least breathe a little easier knowing that the aliens led by Xthlu will have to wait and invade us until they have properly engineered stinky-gas tanks to breathe from.
