The Kepler observatory was launched into orbit in early 2009. Its mission: to search for planets in solar systems other than our own. Their recent results point to a staggering number of planets that share the galaxy with us, many of which orbit their sun in a habitable temperature zone: between 0 and 100 °C. This means that water-based life such as ourselves would neither freeze nor boil away, assuming that the planet has atmospheric pressure similar to Earth. (…)
Based on the approximate value of 100 billion stars in our galaxy, scientists with Kepler estimate at least 50 billion planets (one out of every two stars is expected to have a planet). And 500 million or so of those planets are in the habitable temperature zone.
