Just saw an atricle about Lisa Kaltenegger stating that Pandora like moons (rock that can support life) might soon become a reality...something about a new telescope (James Webb Space Telescope) planed to be set in space in 2014, which is to be able to find such objects...
They are practically stating that life is out there....how much disclosure does one need?
