The Milky Way might host over two hundred planets orbiting around a star, planets that are believed to be able to support human life and any other earth like life, stated a study based on a mathematic calculation of two hundred years old.
Studies of Australian researchers, reported that each star of the Universe has orbiting around it, about two planets that can sustain life. The Milky Way, might host over 200 billion of planets which would allow the survival of human life.
According to the scientists, our galaxy contains around 100 billion stars. Until now, astronomers have discovered 1,000 exoplanets in the Milky Way, but only a few of them could offer possibilities for survival. While in search of planets similar to Earth, Australian researchers, seem optimist, stating that our galaxy might host alone, over 200 billion planets that can support life.
Scientists from the National University of Australia, have used a 200 year old method, called “the las Titius Bode”, which puts the existence of planets on the laws that governed their moving around stars. This practice turned out to be effective, for the researches which lead to the discovery of the dwarf planet Ceres and the giant planet Uranus.
Still, the exactness of this procedure, has been questioned several times. When talking about the Solar System, this method hasn’t been able to detect the asteroids belt, the planet Pluto and many other celestial corps located beyond Neptune’s orbit.
For this specific study, researchers have focused on the multi planetary stelar systems which are hosting at least three planets, detected with the help of the Kepler, spatial telescope.
They have used the law of Titius-Bode to foresee, the orbits, followed by 228 extra planets. This procedure has helped scientists to reach the conclusion that around each star from the Milky Way, there are orbiting at least two planets capable of supporting life.
The areas of the Universe which are called to be earthly life friendly, are the ones that are dependent of the presence of water in liquid state. For the development of life, it is mandatory that an exoplanet receives as much light form its star like Earth receives from the Sun, this would allow the existence of water in liquid form.
