Earth-Like Planets

Introduction
Do you believe that there is life on other planets? Better yet, do you believe that there is another planet that looks like earth? As far as I can remember, there has always been the question of “is there life in outer space? I remember being in grade school wondering if there were humans or aliens on other planets and if they were trying to communicate with us. Around January 1986 the Space Shuttle Challenger exploded during takeoff in front of the entire world. As a teenager, this event was tragic and amazing at the same time because I felt that we were on our way to

However, this information does suggest to the public that we are getting closer and closer to discovering other earth like planets. “We can’t be alone”
The science community is getting very close to discovering earth-like planets and extraterrestrial life in outer space. This is considered a valued assumption among many researchers and astronomers. To date, they have actually discovered more than 800 of these exoplanets amongst the billions and billions of stars in our galaxy. The more planets found like HD40307g, the more they resemble earth with earth-like characteristics (the spinning on its axis, having a night and a day, and orbiting in the habitable zone). Astronomers are also finding them closer to our solar system. Another assumption of these findings are that humans are developing and advancing technology to communicate, navigate, and live in outer space in the near future. NASA said no candidate planet discovered thus far by Kepler "is exactly like Earth," but noted that the spacecraft "has collected enough data to begin finding true sun-Earth analogs—Earth-size planets with a one-year orbit around stars similar to the sun." (Poeter, 2012)
According to space.com, private companies and NASA are working together to take the next step forward of launching humans into outer space. Entering the term space settlement, suggest that
