Found! 3 Super-Earth Planets That Could Support Alien Life

This article is for all the non-believers who are waiting for absolute proof of life beyond Earth. Disclosure is slowly trickling out…

If scientists have confirmed one example, how many other hundreds or thousands of other similar solar systems are in our galaxy?

The habitable zone of a nearby star is filled to the brim with planets that could support alien life, scientists announced today (June 25).

An international team of scientists found a record-breaking three potentially habitable planets around the star Gliese 667C, a star 22 light-years from Earth that is orbited by at least six planets, and possibly as many as seven, researchers said. The three planet contenders for alien life are in the star’s “habitable zone” — the temperature region around the star where liquid water could exist. Gliese 667C is part of a three-star system, so the planets could see three suns in their daytime skies.

The three potentially rocky planets in Gliese 667C’s habitable zone are known as super-Earths — exoplanets that are less massive than Neptune but more massive than Earth. Their orbits make them possible candidates for hosting life, officials from the European Southern Observatory said in a statement.

“We knew that the star had three planets from previous studies, so we wanted to see whether there were any more,” co-leader of the study Mikko Tuomi of the University of Hertfordshire, U.K. said in a statement. “By adding some new observations and revisiting existing data we were able to confirm these three and confidently reveal several more. Finding three low-mass planets in the star’s habitable zone is very exciting!”

This is the first time three low-mass planets have been spotted in the habitable zone of the same star system, and it’s unlikely that astronomers will find any more around Gliese 667C. The star’s habitable zone is packed full, making it impossible for another planet to orbit stably within the zone, the researchers said.

“The number of potentially habitable planets in our galaxy is much greater if we can expect to find several of them around each low-mass star — instead of looking at 10 stars to look for a single potentially habitable planet, we now know we can look at just one star and find several of them,” team member Rory Barnes of the University of Washington said in a statement.

Gliese 667C is the faintest star in the three-star system. From the surface of the planets in orbit around Gliese 667C, the two brighter stars would be as bright as the full moon by night and shine visibly during the day, ESO scientists said.

Gliese 667C is cooler and dimmer than the sun, making it possible for planets that have very close-in orbits to remain habitable. This star’s habitable zone lies within an orbit the size of Mercury’s around the sun, ESO officials said.

    “This discovery single-handedly demonstrates that low-mass stars can be hosts of several potentially habitable planets,” explained Dr. Tuomi.

    “In practice, it means that we might have to double or triple our estimates for the occurrence rate of habitable-zone planets around M-dwarf stars.

    “There might, in fact, be more habitable-zone planets in the Universe than there are stars, which makes it much easier for the future space missions to obtain images of these planets.

    “So, although only a rather simple discovery, its implications might force us to re-think how common habitable-zone planets are in the Universe.”

    I read this piece of writing fully about the comparison of newest and preceding technologies, it’s remarkable article.
