18w many planets are there in our galaxy? That's a tricky question to answer. Are there other planets that
support life? That's exactly what the Kepler mission hopes to discover.NASA launched the Kepler space
telescope, designed to find habitable planets, in 2009. So far it has discovered five new Earth-sized planets
beyond our Solar System. These planets are hotter than the Earth - much too hot for life as we know it. The
Kepler team predict that they will need at least three years to find an Earth-like planet.
letter A, B, C or D on your answer sheet to indicate the correct
The simplest requirement for a planet to have life is for there to be liquid water so the distance from the
planet's sun and therefore temperature is important. There also needs to be the correct amount of air. If a
planet is as small as Mars (half the size of Earth) its weak gravity means that it can't hold on to air
molecules. If a planet is Neptune-sized (four times bigger than Earth) it has very strong gravity and too
much air. So size matters too. The cost of the mission is approximately six hundred million dollars. It is
scheduled to observe until 2013 but this could be extended. Will we be sad if we discover we are alone in
our galaxy or happy if we find that we share it with other life forms?
