A study to be published next month in Monthly Notices of the Royal Astronomical Society has unveiled that many more earth-like planets are yet to be born. The study claimed that when earth was formed 4.6 billion years ago, at that time just 8% of the possible habitable planets that will ever exist were formed and 92% of such planets are waiting to be born.

The researchers have based their findings on the assessment of data gathered from Kepler and Hubble space telescopes. Though star creation process is reduced now, there is enough hydrogen and helium gas present that star and planet formation will keep on taking place for quite a long time now.

As per estimates of scientists, around one billion earth-size planets are present in the Milky Way galaxy. There will be as many as earth-like planets in each of the 100 billion galaxies in the visible universe. The researchers' theory claims that these planets are nothing more than a fraction of the universe's total to be attained in next 100 trillion years.

"Our main motivation was understanding the Earth's place in the context of the rest of the universe. Compared to all the planets that will ever form in the universe, the Earth is actually quite early", said Peter Behroozi of the Space Telescope Science Institute.
