Out of the total 50 billion planets, around 500 million are assumed to be placed in a key zone near their specific stars, which can also prove to be favorable for the sustenance of life.
Revelation was made by the American Association
This disclosure was made by the researchers at the annual meeting of the American Association, for the Advancement of Science.
The scientists revealed that the estimate was made after examining a small portion of the sky, with the help of Kepler.
On the basis of that, the researchers inferred about the number of planets which could be present in the galaxy.
In an announcement made by NASA in the beginning of this month, it informed about the discovery of 1,235 planet candidates by the researchers, out of which 68 planets were found to be similar to the size of the Earth.
These 68 planets are assumed to revolve around more than 156,000 stars.
