NASA admits that there are many earth like planets in the universe – The number will take your breath.
If got might have created only one Universe then it is believed that our galaxy alone can have a habitable planet if around 100 billion. Then according to the number of galaxies estimated we can expect to have 50,000,000,000,000,000,000,000 i.e (5 x 10^22) planets where life is possible.
Scientists believe that there are almost 400 billion stars in our milky way, some say that its trillion but my god knows this. So, according to them, it is not less than 100 billion human habitat planets. Moreover, people don’t know the exact number but it’s just an estimation.
Some other calculation shows that Milkyway alone has a lot of possibilities to habitat 3.2 trillion planets. The calculation is done according to the weight calculation of all galaxies, by doing this we can calculate a number of stars and the number of the same and calculated that our galaxy has 400 billion stars but, the number has a chance to increase drastically.
There is a special research from NASA that they have found 1500 planets that are located within 50 light years from earth. This observation took over six years PLANET—Probing Lensing Anomalies NETwork—collaboration, founded in 1995.
In the year 2013, Dr.Phil Yock from University of Auckland said
“Kepler finds Earth-sized planets that are quite close to their host stars, and astronomers estimate that there are around 17 billion such planets in the Milky Way. These worlds are hotter than our planet, although some could be of a comparable temperature (and could, therefore, be habitable) if they are orbiting a cool star called a red dwarf.”
He continued saying that by estimating Kepler’s law and MOA we can clearly estimate the total number of earth like habitat planets in our galaxy that is Milky Way, and it is predicted that it may contain in the order of 100 billion.
It will, Of course, be a long path from this estimation to actually finding inhabited planets, but it’s not too far to find out. This number will be increasing every year.
If we take a look at the data provided by the Kepler, we’ll know how astronomers believe roughly 40 BILLION Earth-sized planets orbiting habitable planet of Sun-like stars and red dwarfs in our galaxy alone.
Eventually, some astronomical scientists say that there are around 11 billion planets orbiting Sun-like Stars, while some others believe this number is more like 100(one hundred) billion.
