"The first planets beyond our solar system were discovered in 1995. Up to today there were just over 500 known extrasolar planets.
We have found over twelve hundred candidate planets – that’s more than all the people have found so far in history.
Even more significant is that 54 of the planet candidates are located within the ‘habitable zone’ of their host stars and 5 of those are Earth-sized. Before today we knew of exactly ZERO Earth-sized planets within the habitable zone. Now there are 5."
