Earth like Planets Are Yet to be Born

NASA has been using the Kepler observatory for almost 7 years to survey the region of the Milky Way hoping to find a planet with the same characteristics  to Earth. Apparently the agency has had some luck with its search, the most notable discovery is the Earth bigger cousin, Kepler 452.

According to the data collected by NASA's Hubble telescope and the intensive planet searching of Kepler's observatory, in 4.6 billion years ago where researchers theorized that during the creation of our solar system only eight percent of the planet created were potentially capable of becoming a habitat will form in the universe. 

"The main motivation was to understand the Earth's place in the context of the Universe," Peter Behroozi of Space Telescope Science Institute (STScI) stated. "Compared to all the planets that will ever form in the universe, the Earth is actually quite early." 

The universe was making stars at a very fast rate Ten billion years ago. However, only a small fraction of hydrogen and helium gas was involved in the creation. Today the birth of star occurs in a very slow rate, although the universe will continue to cook stars for a very long time since there is a very large amount of hydrogen and helium gas present in the universe. All of the data are shown from the information gathered by the Hubble Telescope,   

"There is enough remaining material [after the big bang] to produce even more planets in the future, in the Milky Way and beyond," Molly Peeples of STScI said. The survey of Kepler's planet shows that earth sized planets in a habitable zone are ubiquitous in our galaxy.

Scientist believe that there are almost 1 billion Earth-sized planet present in the Milky Way. A portion of that planets are presumed to be rocky based on the survey data gathered.  

NASA noted that one of our biggest advantages of rising early in the Universe is our ability to trace our lineage by using the Hubble telescope. The evidences of the big bang and cosmic evolution will be wiped away 1 trillion years from now by the runaway expansion of space.
