Our Milky Way Galaxy may be home to 2 billion planets that have the right conditions to support life. These planets have the correct temperature for liquid water. While no one knows what alien life would look like, if it is anything like life on earth, it would need water to keep alive...
Scientists now estimate that there are as many as 50 billion planets in our own Milky Way galaxy, reports theAP. More interesting, 500 million of them may be in zones where life could exist. These numbers come, of course, from NASA’s Kepler telescope, which was launched specifically for ...

Extrapolating to the Milky Way as a whole, the researchers predict that at least 500 million of the galaxy's probable 50 billion planets reside in the habitable zone. That certainly offers a hopeful sign for the existence of life beyond Earth. Kepler has also identified 68 Earth-size planet ...

Our Milky Way galaxy is home to at least 100 billion alien planets, and possibly many more, a new study suggests. "It's a staggering number, if you think about it," lead author Jonathan Swift, of Caltech in Pasadena, said in a statement. "Basically there's one of these planets per...
