NASA reported that our galaxy is filled with potentially habitable planets, around three-hundred-million of them. The Kepler Space Telescope of an American space agency consumed 9 years on a planet searching mission, progressively detecting thousands of exoplanets in our galaxy before finishing the fuel in 2018.
That figure is a rough estimate on the conservative side, and “there could be many more,” says NASA. https://t.co/92TOO04Zvi

Mission’s primary question is still unanswered, which is ‘how many planets are habitable?’
Scientists all across the world studied Kepler Space Telescope’s data for many years, and they believe that they have obtained the answer. There are around three-hundred-million habitable planets in our galaxy, which means that the rocky worlds that are capable of holding liquid water on their surface, a study published in The Astronomical Journal.
In a news press, NASA described that the number is a rough calculation on the conservative side, and there could be several more. Moreover, several of those planets could be considered as interstellar neighbors; the closest is near to twenty light years away.
A good portion of planets might be habitable
In a press release, Steve Bryson (lead author) and NASA researcher said that Kepler already told them there were billions of more planets, but now they know a good portion of those planets might be habitable.
Although this outcome is far from the final value, and water on the surface of the planet is one of many other factors to support life, and it is enormously exciting that they counted these planets are this common with such precision and confidence.
This research was global teamwork between scientists of NASA who operated on the Kepler mission and researchers and scientists from international firms from Brazil to Denmark.
According to NASA’s estimates, there are around a hundred to four-hundred billion stars in our galaxy (Milky Way). It means that each star in the sky likely hosts one planet minimum, which in turn describes that there are probably trillions of worlds out there, from which they have just confirmed and founded a few thousand.
There are many factors that determine whether a world or planet is habitable, including its chemical composition and its atmosphere. Moreover, scientists searched for those start that is similar to our Sun in temperature and age. Scientists even searched for exoplanets that have a similar radius to Earth, and they cited those that were probably to be rocky.
