It used to be billions and billions, but now it’s in the trillions!

“There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe.” –Carl Sagan

Come get the science behind this amazing story, including how we know, what it means and what we’ll even have the potential to learn in the near future. Enjoy the latest Starts With A Bang podcast!
