Planets in the habitable zone around most stars, calculate researchers

Astronomers have discovered thousands of exoplanets using the Kepler satellite. By analyzing these planetary systems, researchers have calculated the probability for the number of stars that might have planets in the habitable zone. The calculations show that billions of stars in the Milky Way will have one to three planets in the habitable zone, where there is the potential for liquid water and where life could exist. ...read more
