NASA’s Kepler space telescope has discovered more than one hundred Earth-like exoplanets. Nine of them are liveable because there is a possibility of water availability in a liquid state on these planets. The discoveries are a part of 1284 new planets.
For the first time in the history, a massive number of planets are found. NASA is very hopeful that they will soon find a planet that will be the carbon-copy of the planet where we currently live in.
Scientists studied 4302 celestial bodies which were discovered by the Kepler space telescope in between 2009 and 2013. 1284 bodies out of them are most likely the planets.
Dr. Natalie Batalha, a great investigator, an astrophysicist at NASA Ames Research Center and the Mission Scientist for NASA’s Kepler Mission, says that “So by my back of the envelope calculation there are tens of billions of potentially habitable planets in the galaxy.”
She said that more than 24% of the stars are possibly in the habitable zones and they are 1.6% smaller than the size of the earth.
Dr. Batalha further stated that “If you ask yourself where is the next habitable planet possibly to be, it’s not further off than about 11 light-years, which is very near.”
Among the discoveries, two planets (Kepler 186-F and Kepler 452-F) are very similar to the planet Earth, on the basis of size, temperature, and the energy they get from their star.
Paul Hertz, Astrophysics Division director at NASA says that their final target is to observe the light of a habitable planet and examine it for the water vapors, oxygen, methane, and carbon dioxide.
These gases can hint us about the presence of living community system on these planets. Dr. Timothy Morton, from Princeton University in New Jersey, says that most of the discovered planets are 1.2 to 1.9 percent larger than the size of the earth.
