Scientists predict earth-like planets around most stars
Canberra, Australia (SPX) Feb 06, 2015
Planetary scientists have calculated that there are hundreds of billions of Earth-like planets in our galaxy which might support life. The new research, led by PhD student Tim Bovaird and Associate Professor Charley Lineweaver from The Australian National University (ANU), made the finding by applying a 200 year old idea to the thousands of exo-planets discovered by the Kepler space telescope. They found the standard star has about two planets in the so-called goldilocks zone, the distance f ... read more
