It’s Official: Astronomers Have Discovered another Earth

10

NASA’s Kepler Space Telescope discovered an Earth-like planet circling a nearby star within the Goldilocks zone of our galaxy. Kepler-186f is around 500 light-years from Earth in the Cygnus constellation. The habitable zone, also identified as the Goldilocks zone, is the area around a star within which planetary-mass objects with enough atmospheric pressure can sustain liquid water at their surfaces.

While it has been projected that there are at least 40 billion Earth-sized planets circling in our Milky Way Galaxy, this specific finding is labelled the first Earth-sized planet to be discovered in the habitable zone of another star.

In addition to Kepler-186f, there are 4 other planets that circle a nearby star within the Kepler-186f system. What this means is that if the neighbouring star to this planet is just like our Sun, then the likelihood of life on this planet exponentially increases.

“We know of only one planet where life survives – Earth. When we hunt for life outside our solar system, we emphasis on discovering planets with features that mimic that of Earth,” said Elisa Quintana, research scientist at the SETI Institute at NASA’s Ames Research Center in Moffett Field, Calif., and lead author of the paper published in the journal Science. “Discovering a habitable zone planet similar to Earth in size is a major breakthrough.”

The neighboring star to Kepler-186f has half the mass and size as our solar system’s Sun and only gets one-third of the energy that we get from our Sun. Kepler-186f circles its star once every 130 days

  1. .. at something like 600 light years from Earth what are the possibilities of ever communicating with Keper?
    I appreciate in terms of galactic distances this is relatively small none the less significant in human terms.
    Thanks.

  2. 1000 years to ask one question and get a reply. Millions of years to travel there. We won’t be going there any time soon…. like thousands and thousands of years to develop that kind of technology. 80,000 years to travel to our nearest star system and its only four ly’s away. I think we are bound to our solar system and may never reach the stars unless an advance race shares their technology with us.

    • I gotta say, I think your wrong. There really is allot of work being done around the earth right now, has been for a long time. If we can find a theory of everything, or most things anyway, who’s to say there is not a way to do this. If u believe out there there is probily a race that can travel anywhere, or at least huge distances, what’s to say we can’t. The hadron collider is looking at new as yet unfound particles we have not detected before. These things could tell us soo much about the universe it’s crazy. Two hundred years ago, a mobile phone would be seen as magic. Not possible? But hear it is. And now not very tech at all. Easy to make. As soon as something new is found, the human mind expands and tec explodes. I would bet my children will see some crazy shit in there life time, and I’d bet there kids will see other planets on tv, wether a human goes there or just something we send to find out, it’ll happen, and it won’t take thousands of years ether. Technology is growing faster than ever, if it keeps growing at this rate, wow, we will see the stars believe me!! Peace

  3. Very valid answer Jack, one that had put a stopper on theorists throughout the last 100yrs.
    What we need is to rethink physics. Specifically travelling from A-B. Thinking of their coordinates in 4D. Instead of 3D where the fastest travel between them is a straight line.
    Quantum Physics suggests time lines, bending space and anti-gravity.
    NASA and the world’s elite are already producing element 112 ununpentium in the Hadron Collider at CERN, this is the most likely way to achieve anything close to the speed of light 186,000 miles per second.
    But you are correct we are a long way off, but not that long.

  4. The secret is save the earth and not go to another earth like planet we have to understand this. Earth is our home in this univerce and is the most beutifull planet
    thats it

    • Bravo John! I like the dream of Inter galactic travel, hell I would love interplanetary easy jet travel. But being realistic, Kepler, though pretty in mock-up is just a fantasy. We ain’t goin there, no way no how.

      I am of the early years of sci-fi stories and fantasies gang who dreamed of being on the moon in bases and small colonies by now. Heinlein, Norton, Asimov, Bradbury all gave us kids of the 50’s, 60’s the hope that might happen. When we took that first step on the moon, our dreams were truly coming true.

      But it all failed and the Rich just got richer and the whole thing turned into a scam. Hate overcame science, greed overwhelmed mankind need to escape to our sister moon, and eventually planets and we are now facing extinction by our own hand. Sad end to a great bunch of dreams.

  5. If it doesn’t have an orbiting moon, then it’s not going to be like Earth. Our moon creates the tides, which drive the wind, and creates weather here. The goldilocks zone is only a part of the equation.
