Kepler-452b Kepler Announcement 23 July

[Techpriest93]

Who knows what they could of found?

Earth type planet in our back yard?

Maybe a new type of exotic planet?

Maybe a replica of our solar system?

Maybe an open cluster with each star having 1-2 earth sized planets?

Maybe they have finally been looking long enough that they are finding Jupiters, Jupiters everywhere! Oh, or Neptunes too...

Maybe they have found a star with 2 orbital planets at 90 degree angles to one another?

... Maybe kepler is dead? In that case, this would be a final farewell and a ceremony to look back on the achievements of the little sat.

(Or many they got funding for spaceX to launch another satalight!)

me neither, is there any alternative source? or could someone keep updating this thread? and add some sarcasm signs to my Tsoukalos post? done

ANNOUNCEMENTE - Kepler-452b: Earth's Bigger, Older Cousin

[_Augustus_]

They found another earth! Woot!

[Frida Space]

HERE IT IS http://www.nature.com/news/earth-sized-exoplanet-found-orbiting-sun-like-star-1.18048

[_Augustus_]

Well, it's a new Earth.

Sweet!

[Aethon]

On now.

Wow!!

[Aethon]

Close Earth analogue found around a G2 (sol like) sun with a 385 day length. Kepler 452 b. Slightly older than Earth, it has spent 6 Billion years in it's habitable zone.

Probably 5x(+ or - 2) the mass of Earth and only an even money chance of it being rocky. (meh)

1400ly away.... star estimated 1.5 billion years older than our sun...

Fermi paradoxed his way into this discussion again... :-/

[Mitchz95]

Guess it's a good thing we kept Kepler going.

EDIT: Just got cut off.

[AngelLestat]

it said that it is 5 times more massive than earth, so not sure if the density will change or not...

Surface gravity?

The most probably with that mass and even a bit lower light pressure, that it will have a more dense atmosphere.

How much it will be hard to know.. but if the atmosphere is very dense, then it will have high surface temperatures as venus.

[_Augustus_]

Well, assuming that Alcubierre drives are possible, and that the IXS could get to Alpha Centauri in 2 weeks, the IXS warp ship could get to this place in 13 to 14 years.

[Albert VDS]

Wow, great news.

Add another target for JWST to look at.

Edited July 23, 2015 by Albert VDS

[Thomassino]

We will know more when JWST will be launched. It can perform spectrographic analysis of exoplanet's atmosphere.

[Mitchz95]

Its ESI is only 0.69? That seems a bit low. I guess they're waiting for more data before they update it.

[LordFerret]

Interesting news!

Someone mentioned Kepler not being able to detect planet atmospheres, but I've seen several scholarly articles related to transit detection to the contrary. I'll guess this announcement is the proof in that pudding.

[Loerelau]

NASA website was full for me.

Well, it's much larger than earth. In terms of size, there have been better candidates.

Arent they just detecting that there are atmospheres, rather than actually seeing what the atmospheres are made of?

It's been updated, Kepler-452b is now the second most earthlike exoplanet known.

[_Augustus_]

Kepler-452b was announced just 2 hours ago at a NASA press conference.

It's ESI? Originally calculated to be 0.69, Kepler-452b's ESI is now 0.862. This makes it the second most earthlike planet to date.

So what else do we know about this planet? Well, read the Wikipedia article. (I contributed to it!)

[Mitchz95]

Very exciting! Let's not get ahead of ourselves, though. By current definitions, Venus is Earth-like as well.
