Oldest Planetary System Discovered, Improving the Chances for
Intelligent Life Everywhere

Using data from the Kepler space telescope, an international group of
astronomers has discovered the oldest known planetary system in the
galaxy - an 11 billion-year-old system of five rocky planets that are
all smaller than Earth. The team says this discovery suggests that
Earth-size planets have formed throughout most of the Universe's
13.8-billion-year history, increasing the possibility for the
existence of ancient life - and potentially advanced intelligent life
-- in our galaxy.
"The fact that rocky planets were already forming in the galaxy 11
billion years ago suggests that habitable Earth-like planets have
probably been around for a very long time, much longer than the age of
our Solar System," said Dr. Travis Metcalfe.
