How Kepler Has Profoundly Changed The Perception Of The Universe

Kepler has opened up a whole new universe in the understanding of our place in the cosmos. Only about 20 years ago, we didn’t know if there were any other planets around any other stars besides our own, now we know we live in a galaxy that contains more planets than stars. Every star in our galaxy has on average 1.6 planets in orbit around it.

Our own galaxy contains over 200 billion stars, with approximately 40 billion much like our own sun. Now, according to Kepler, there are nearly 9 billion planets roughly the same size as Earth. These planets will have the same potential as having liquid water on their surface, provided they are located in the circumstellar habitable zone.
