First Earth Twin that's Habitable to be Announced By NASA on Wednesday?

There is a special encounter session planned for tomorrow at Lockheed Martin.

All the bigwigs are going to gather in a circle, join hands and pray to whatever higher power they might believe in, to please send us a hostile planet.

statistically, red dwarfs have a 1/6 chance of having an earth sized planet in it's rather snug life zone.
alpha proxima; the closest star to us is a red dwarf. as are Barnard's star and wolf 359. We have Three of them within 6 light years with the closest one being just 4.26 ly away. and within ten LY there are even more.

Hmmm... actually there's research indicating close to half of red dwarfs could have a planet in the habitable zone:


Statistics of Nearby Earth-like Planets Around M-dwarfs Stars

94% likelihood of a habitable planet around an M-dwarf within 10 light years of Earth.

Yup you are right

Thanks for the heads up JadeStar. Realistically, the universe is too vast and it's probably not too far off in our distant future that we find out there are many Earth-Twins, and not too far off from that time, we may find they are booming with life. Interesting times indeed!

I agree with you, I bet the Galaxy is teeming with life. I hope that soon or they may already have, developed some type of wormhole generator or FTL translator that can get us to said system in minutes or seconds instead of eons. I truly think that the wormhole will be the key.

kinda off topic for the thread but here: www.youtube.com...

pay attention to the bit where he says you can change the resistance of space to being warped which reduces the energy requirements and removes the need for exotic matter or energy. but any further discussion should be in an appropriate thread of which i think there are two recent ones.

in fact i linked the warp video into one of those threads just now. www.abovetopsecret.com...

I believe it's more likely to exist a planet exactly like earth in size and "earth-sun" distance than no habitable planets at all. There are simply too many planets out there, the possibilities are too big.

SIGN ME UP! Let's go!

I'd be pumped to travel to this place for the first time. What a great way to die...Going down in the history books as one of the first people to embark on this new world and explore as much of it as possible...

...One can only dream

So has the announcement been made?

Have I missed it?

Sorry to burst your bubbles guys, but that index that is supposedly new which was posted in the OP is in fact over 2 months old. I wouldn't be surprised if there was no announcement...

The index wasn't the OP of this OP, the OP is the news teleconference coming up in about 90 minutes.

EDIT: In two minutes!

CONFIRMED: They just said they found an Earth 2.0

I called it


CORRECTION: They did NOT say they found an Earth 2.0. They said the new verification technique gets them 'significantly closer" to finding one among the candidates.

They did highlight Kepler 296 f which is what I thought they were referring to as Earth 2.0 but it is not an Earth Analog as its radius is nearly twice that of Earth.

Nice work. They've also announced the confirmation of 715 exoplanets (ah, see you've got the chart up, thanks, I couldn't figure out where to find the graphics).

That list was of planet CANDIDATES which had high ESI (Earth Similarity Index) numbers. It was not 'old' it was from the latest Kepler data release until today.

My prediction based on murmurs was that one of those planet candidates that had a high Earth Similarity number would be announced as confirmed.

So a bunch of those candidates may so be confirmed planets. They aren't yet though. Sometime this year one probably will be, based on the speed at which this new verification process works. They will have gone through half of the candidates by the end of the year.

I hope this clarifies things. Stay tuned for a bunch of news stories about the new Earths.

No they didn't. They said this new validation method will bring them closer to finding an Earth 2.0.

Im still uneasy about calling them new "earths".

Until we get a picture of there atmosphere they could be very inhospitibal.


Not to say this isnt big news or very important and I certainly think there are some twin earths out there.

But arnt some of you (especialy ones that should know better ) getting abit ahead of yourselfs?

So to sum up, they're announcing a new method to validate exoplanets in solar systems with multiple planets. By going through the first two years of Kepler data with this new method, they can verify 715 additional planets. Of the 3,601 planet candidates Kepler had found previously, only 246 had been verified because the verification relied on observations from other telescopes and methods. Now, as long as the planets are part of a multi-planet system, the verification can be done entirely with Kepler data.

So of the 715 new planets are orbiting 305 stars. 94% of the newly verified planets are smaller than Neptune. And 4 of newly verified planets are inside the habitable zone of their stars (no info yet on the size of those four planets, so I don't know how Earth-like they may be).

You're right.

To me it seemed that he was referring to Kepler 296 f as it. But at around 2 Earth radii clearly its not an analog.

The takeaway is that they should be able to verify many of the high ESI candidates.

They expect 90% of the planet candidates to be verified. This new technique can help verify the ones around K and M dwarfs a lot faster than previous techniques.

I expect the Planetary Habitability Lab at Arecibo to update their graphics in the next week or so.

The guy from SETI gave the radius of each of the 4 and the smallest was around 2 Earth radii. (~1.91 Earth radii)

Yes. Only have radii, do not have masses yet. With both we can get density.

Anyone who missed the presentation all the stuff (graphics, animations) used are on this page.

No you didn't. Saying they have a better way of finding Earth 2.0 is not quite the same as actually FINDING Earth 2.0. Stop patting yourself on the back; no one else is.
