Found! 2 Earth-Size Alien Planets, the Smallest Exoplanets Yet

I'm sorry but I can't help but find these stories somewhat humorous. You mean to tell me that 950 MILLION LIGHT YEARS away they can tell how big a planet is and how close it is but yet they can't provide us with good photos to our nearest planets? Point that god damn Keplar telescope at one of them damn it.

It's not about distance, it's about light. If there is not enough light on the object it cannot be visible to us.

Yeah Kepler doesn't care about distance, it can see if a planet is in a certain zone (hot, habitable, cold, frozen ect) by watching the planet pass in front of it parent star. Then it depicts the light and how much light is visible when it passes. It actually a pretty accurate way to see size, mass and what zone it is in.

While I am excited about this new find, I am so tired of scientist making the claim that a planet has to be in the "Goldie locks" zone in order to be habital.

WE feel that WE are in the "Goldie locks Zone" because WE live here....

I am certain that the inhabitants of Venus feel that THEY are in the Goldie Locks Zone because THEY live there...
Earth could be viewed as too cold.


I am certain that the inhabitants of Neptune feel that THEY are in the Goldie Locks Zone because THEY live there...
Earth could be viewed as too hot.

We will never progress as a society and expand our knowledge and acceptance of the universe as long as we remain undoubtedly ARROGANT= "Life can only exist where it has what WE have...blah blah blah".

Earthlike Planet, Gliese 581 (Gliza) habitable zone?

Hello Gliese 581d inhabitant. Can you help us humans travel through space and become smart like you. Please do not eat us we are a friendly race. Angus Pigott Canberra, Australia

Did they say that was a habitable planet or a goldielock?

you must know something about venus & neptune the rest of us dont

reply to post by SloAnPainful


its another quite bad planet being hyped by astronomers notice the words "could be" etc . Although that youtube clip doesn't state which of the gliese planets its talking about. But theyre all pretty far away from being an earth analogue.

Not 950 million, loose the million.

Wow, amazing. Thank you for posting and all the informative information.

You should all realize, Kepler only sees planets that occlude their parent star.

In other words, the plane of the orbits of any planted I'm the system have to be edge on when viewed from earth.

Any systems whose planets are orbiting with top down ( or bottom up) view will not be detected


I believe this to be a significant number that we are blind to.

yeah but we know the chance of the correct alignment something like 0.5% ( for earth size in earth orbit) so we can figure how many we dont see.

Yes.

That our earthly human life is not the only life form in the universe...

that we are not the supreme creatures of the universe.... and

that life MOST DEFINITELY can exist outside of Earth, irregardless of its ability to sustain human life....

Funny though a few years ago skeptics were saying that planets were a rare thing, now they are common, and as pointed out we are only seeing a small percent as they move in front of the home sun... But even those few that we do see, as of 27 April 2010, 453 planets have been discovered.

Gliese system is cool because it is only 20ish light years away, just around the corner

reply to post by zorgon


well in the 1950s astronomers thought planets were rare because they thought planets were created when stars collided into each other. Which would be a rare event. But since the 1970s astronomers have thought planets to be common. Its detecting them that is hard.

Looks like G is our best bet for life and habitility (sorry I know thats spelled wrong >.

reply to post by SloAnPainful


i dont think gliese G has been confirmed. Its still controversial because of this. It might be there it might not.

habitability? not good i think. The tidal forces exerted by the star at that distance are likely to cause great internal and surface disruption- not a good place to build a house . Its more likely to have oceans of magma than water like earth. Then you've got the problem of tidal locking and the light spectrum of the star. (mainly UV)

Still it makes me wonder what these places are like.

Ah thank you sir...not sure why I put MILLION in there, lol.

I've been thinking the same thing too. How do they know that another species can't live off purely methane or hydrogen? They keep stating that water is the gateway to all life. Well if it's human then more than likely yes but I have to think that many species have the ability to adapt to it's environment.

reply to post by HawkeyeNation

How do they know that another species can't live off purely methane or hydrogen?

they dont but they do know complex life & large animals can live off oxygen.

tell me this : if we detected a planet with a hydrogen atmosphere how would we know it had this hydrogen breathing life there? we wouldn't because we have no reference for that kind of life.

But if we detect an earth-size planet with a lot of oxygen in the atmopshere, the only way we know to produce oxygen is from plants & some microbes. So we have either discovered a planet with life or a planet that has a new way to produce oxygen continuesly without life. . Our bets would be on life in this scenario

this is the goal of future planet hunting telescopes. To detect earth-size planets with oxygen in the atmosphere. The holy grail Earth 2.0
