Opening moment.

Recent data has suggested that about twenty percent of stars in the Milky Way have a planet that 
is roughly earth sized and orbits in the habitable zone. This zone is the distance from the star where
 liquid water can exist, meaning that twenty percent of the stars in our galaxy could have life. This 
has enormous implications. One hundred billion stars exist in our galaxy, meaning twenty billion 
could potentially have life bearing planets. Despite that many more things are required for life to 
succeed on a planet as we know it, such as a magnetosphere, this still means that there could be 
billions of planets out there that are habitable. In terms of ourselves, this can spur future space 
Exploration, along with proving to people that life almost certainly exist off of our planet.
