According to a recent issue in the Journal of astronomy(The Astronomical Journal)There are about 300 million potential human habitable planets in the Milky way, according to the research paper published on. The study is the result of a survey of exoplanets from 2009 to 2018, suggesting that liquid water exists on these potentially habitable planets. NASA also said in a press release that this is only a conservative estimate, the actual number may be more.


This scientific research mainly uses NASA's Kepler exoplanet Hunter satellite to provide scientists with a lot of information about the composition of distant planets and stars in orbit. The researchers used this information to figure out how common earth like planets are.

If that number is even close to real, it means that there are millions of habitable worlds lurking in other parts of the galaxy. Of course, whether these planets have life is another question that we can't answer in a short time.
