Rocky planets with conditions suitable for life may be more common than previously thought, and they may be right here, in our own galaxy. More than half the Sun-like stars in the Milky Way could have planetary systems like ours. Are they calling us? Can we communicate with them? Are their inhabitants here on earth, interacting with us? In BBC News, Helen Briggs quotes US astronomer Michael Meyer as saying, "Our observations suggest that between 20% and 60% of Sun-like stars have evidence for the formation of rocky planets not unlike the processes we think led to planet Earth. That is very exciting."

They may not just be calling us, they may be here! And sometimes they bring us messages we need to hear.
