Have you ever wondered what is out in space that has yet to be discovered? Over the last century alone, we have put a man on the moon and launched a global partnership in the International Space Station that is opening up the possibilities for future exploration.
Thanks to advances in technology, scientists and researchers have been able to gather more information about stars, planets and other celestial objects in the universe. Scientists estimate that there are between 20 and 40 billion inhabitable planets that are within our Milky Way galaxy. The Kepler Project, NASA Discovery mission #10, has confirmed 167 planets in the galaxy and over 3,500 planet candidates. Kepler has led to a 78 percent increase in the number of Earth-sized planets that have been identified. Humanity has made a number of significant steps when it comes to astronomy over time and the future is still bright for what is still to be discovered.
