One of the questions that get asked most often when it comes to space is, 'Does life in space exist?' The thing is, that it is hard to believe that there is no life in space. Due to the fact that there are so many different planets in the galaxy alone, there has to be at least one or two other planets that support life like Earth does. Astronomers have only scratched the surface when it comes to exploring other planets in space.
The people who study different stars and look for different planets haven't even discovered a fraction of the stars that are in the universe. In 2016 scientist have discovered around 2000 of the billions of planets in the galaxy. But we're not just limited to the Milky Way, there are trillions of other galaxies in the universe, each one could possibly harbor a planet that is able to support life like our home, the Earth. The process of finding planets is also getting quicker as time goes on, any day could be the day when we find like in outer space.
There are a lot of requirements for a planet to be deemed habitable for life. One of the biggest requirements is that the planet needs to be big enough, so it has its own atmosphere. Another requirement is that the planet is in the habitable zone, meaning it isn't too close or far from the sun. The reason why this is, is because of water. If a planet with water is too close to the sun, all the water will evaporate away, and if the planet is too far from the sun, all of the water will freeze over. Even with requirements like these to be met for a planet to be habitable, space is so large that there must be other planets that can support life. It might take a while, but scientists will eventually find another planet that can support life.
