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. A little disingenuous to present this as breaking news. The discovery was announced almost exactly 4 years ago.

  2. Wow! I'm 154 in Kepler-186f years!! (I look pretty darn good for my age)

  3. LOL did you read this news from Internet Explorer?

  4. The rendering of the picture is questionable. 500 light years away and showing features on the surface! Waiting for rainfall totals in next 'episode'.

  7. This article is in DIRE need of an editor.

    "NASA’s Kepler Space Telescope discovered an Earth-like planet circling a nearby star within the Goldilocks zone of our galaxy." - makes it seem that position in the Galaxy has bearing on the Goldilocks / habitable zone of the star. It might, but not out here in the spiral-arms. "of our galaxy" needs deletion and the rest of this sentence, rearrangement.

    "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." - The STAR gets energy? Maybe the star gives off this much energy. And then there's the question of what energy the planet gets from its own star (insolation). I assume you mainly mean the former. So say that!

    These popped up at first glance. There are certainly other errors. Send this article back to its writer.

  8. Circling a red dwarf. Frequent flares. No atmosphere. Try again.

  9. Until we have warp drive I suggest using molten-salt Nuke reactors and the EM drive. It ought to not take us 750 years to make it. No problem! But best bring lots of molten fluoride salt fuel!

    Suspended animation anyone?

  10. Awesome post. Very helpful article I am a regular visitor of your blog and appreciate you taking the time to maintain the excellent site.

    Recording a quickbooks refund from vendor Online is one of the confusing bookkeeping tasks. Lots of people overthink it. This video demonstrates the steps.
