It's Official: Astronomers Discovered Another Earth


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.
What does this mean?
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. I'm calling BS on the photos. There's no way we have that detailed a picture of an object 500 light years away. They used to be careful to put "Artist's Rendition" under such photos. They need to go back to doing that.

    1. It is designed to keep the funding going.... they need a supply of bigger and better stories, lots of sensational pictures, to show that the last billion dollars was money well spent..... the next billion dollars will give more bang for the buck...... and the billion dollars after that is gonna be the one that really does the trick. It's like an election.... we are always 1 election away from good times... but no matter how many decades go by and how many times people believe it.....it still remains one election away.

  2. I can not believe, how many people, take the things that Men in Labcoats tell them as fact, without even thinking critically about what they are being told.
    I pointed a telescope at a star so far away... that all it looks likes is a little white blob... and I can see that this tiny smear of light grows .0001 of a percent dimmer about every 12 months as a planet, that I can not see... orbits it..... and this planet is just like Earth, which implies blue skies, cute little furry animals.... oceans and lakes with lil fishies swimming around......... and if you just give us the cash to make this uber telescope... boy oh boy will we have some new stories to tell you.
    So, one day they are saying that they hardly know a thing about the planet right next to us........ with rovers and orbiters in abundance...... but can tell you all about a planet, they can not see.... circling a star billions and billions and billions of miles away..... a star that might not even be there right now... it could have went nova 100 years ago and we wont even know for another 400 years. Stop worshiping men in labcoats..... They dont like to remind people they are guessing and that their guesses often turn out to be wrong. If they can not even tell us if the planet right nextdoor was ever inhabitable without analyzing a scoop of dirt to see if there are any traces of past life in the soil..... why on Earth would you believe they can tell you with certainty that any story like the one in this article is factual.

  3. You thought that was a real picture of it?

  4. Ничего удивительного и придёт время, когда люди будут удивляться тому, что не догадались раньше каким образом можно получать нужную информацию.
