It’s Official: Astronomers Have Discovered another Earth

22

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

      • Can’t agree more with you. I think this is really a matter of time or as Jack Wagoner says we might be bound to our solar system.
        Taking into account that the universe is still expanding at approximately 160,000 mph (74kps) we might never leave our galactic backyard unless we become a type 2 civilization and have enough energy management to play with space/time, wormholes, anti-gravity, or teleportation totems.
        Anything less, will take us eons just to visit our entire solar system.

        • That is why I feel that we aren’t being visited by aliens from outer space. I this we are being visited from people in the future. Just my theory.

    • That’s a very sceptical way of looking at it. In the last 50 years technology has improved exponentially, so imagine 500 years, then a 1000, I think by then we will at least be travelling outside our solar system if not further.

  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.

      • …Except maybe for that one decent-sized asteroid that collides with Earth. We have a lot to make better on Earth for sure, but I really don’t think it’s wise to keep all our eggs in one basket..

    • Who says it needs to be either or? There are enough people and enough resources to potentially do both, as long as we respect and properly manage the resources that we have. Of course since we don’t know what potential future solutions to speed of light limitations of travel there might be (assuming they can be found), we cannot really specify what resources that will require.

      Google from wiki page (not the most reliable of information resources, but…) “NASA’s budget for financial year (FY) 2020 is $22.6 billion. It represents 0.48% of the $4.7 trillion the United States plans to spend in the fiscal year.” Even if you include other potentially relevant non-NASA research only in the US, and bump it to 1% that’s still an incredibly small amount of the total money spent in the US every year. I’d say investing in it is money well spent. I’d also say there is likely room to invest the rest of the money better, change our lives and ways of industry, and our capitalistic economy often immediately to the exclusion of sustainability etc to `save Earth’ — by which of course we mean to keep it habitable and pleasant for humans, the planet itself will after all do perfectly well without us!

  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.

    • Lots of folks keep trying to make that point in all its various forms, but it is simply incorrect. There are no disposable planets. There is no easy Plan B. We can’t reach any similar planet outside our solar system and it could be centuries or never before we are. Have you even considered those the best nearby exoplanets may already be occupied? Because it will be so incredibly difficult, terraforming Mars will teach us how precious Earth really is, not disposable at all, because the struggle to terraform Mars will teach us to appreciate Earth far more profoundly.

  6. I love love this thread. I wish we could all be sitting around the table having this discussion. HOWEVER, my reality today, I am sad to say, we cannot even bother ourselves (as a species) to work on ending a pandemic, sustainable living, etc.. We are a selfish greedy bunch of aliens. If increased technology and intelligence is indeed a fact, we havn’t gained much since, say…1918. Thank God for think tanks such as yourselves… Keep the dreams alive….and always remember that Dreams cannot come true without actions….

    • It just the way one thinks. All the statement made are based on the outside progress we see, give a break and think differently. Instead of taking matter from point A to point B think of creating same matter. Just go in details of how matter is created but not by the traditional way, go in deep in your own hierarchy start from womb. What we are saying is already achieved, we lack in awareness as the facts and findings are not in main stream

  7. Comment: great topic here, y’all heroes who will be remembered for saving this beautiful planet, may Gods favour be upon us to live life to our full potential🙏🙏
