Fact of the Day: Many Planets

The Milky Way Galaxy has an estimated 200-400 billion stars, and it's assumed that for each star that there's at least one planet. Another estimate is that about 1% of those planets are in their Goldilocks zone (i.e. not too cold, not too hot) and if that was true then there would be at least 2 billion planets suitable for some form of life.
