Now There Are Two

Mark Swain and his team have discovered a second exoplanet that contains the chemical building blocks of life-as-we-know-it in its atmosphere. Both worlds are gas giants, however, and therefore unlikely to support life.

Still, the fact that the building blocks exist in these two worlds suggest they might exist in many Earth-like worlds, as well. The Kepler spacecraft is already looking for such worlds. NASA is anticipating making some amazing announcements through the next decade.
