Scientists have estimated the first cosmic census of planets in our galaxy and the numbers are astronomical – at least 50 billion planets in the Milky Way.
And some 500 million of those planets are in what is known as the Goldilocks zone, where the climate is thought to be not-too-hot and not-too-cold, and life could exist.
