Another earth Kepler-186F found, life probable.

Only 500 light years from us in the Cygnus constellation:
This is a big breakthrough:
NASA has discovered another Earth-like planet orbiting a nearby star within the habitable zone using the Kepler Space Telescope. Labeled as Kepler-186f, it is about 500 light-years away from us in the Cygnus constellation.
“The habitable zone” has also been referred to as the goldilocks zone. This zone is the region around a star, within which planets with proper atmospheric pressure are capable of supporting liquid water on their surfaces. It is estimated that there are at least 40 billion Earth-sized planets within the Milky Way, but this planet they’ve just discovered is the first Earth-sized planet to be discovered in the goldilocks zone of another nearby star.
Besides Kepler-186f, there is also 4 other planets that orbit the same star. This means that if the nearby star is similar to our Sun, the potential for life on Kepler-186f exponentially increases.
“We know of just one planet where life exists – Earth. When we search for life outside our solar system we focus on finding planets with characteristics 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. “Finding a habitable zone planet comparable to Earth in size is a major step forward.”
The nearby star is half the size and mass as our sun and Kepler-186f only receives 1/3 of the energy we get from our sun. Kepler-186f orbits its star once every 130 days.
Pretty exciting advancement:
and only 500 light years away! :)
only 2,939,249,910,000,000 miles or so...
That's almost 3 quadrillion miles. A number so high I don't know what to compare it to.
it's like... a lot.
my calculator doesn't have room for more than 100 million.
my brain stops at about a thousand!
Yeah, as humans it's hard for us to count past a thousand.
So 3 trillion thousands are really hard to conceive. :)
Reddit comments on Kepler 186-f:
*Note this discovery happened in April 2014.
There are some gigantic assumptions to concluding that the Great Filter is inevitably the solution to the Fermi paradox. We've just now, in the last 0.002% of human civilization, been able to even detect potentially habitable exoplanets. Is it more likely that: 1) All civilizations wipe themselves out, thus we detect no life.or
2) We, thus far, have insufficient instrumentation to effectively detect life, or potentially improper assumptions of what life looks like throughout the universe. (Methane based vs. Oxygen based, for example)?
I think #2 is more likely, but we'll see.
A SETI researcher says there's greater than 50% chance Kepler 186-F contains life:
