Hi Waspie

What about the claims of "Earth Like Planet Found"? Such as the recent KOI 172.02?
Speak to the L. He's the one making statements about there being no Earth like planets, not me.

Even if the planet is not 'Earth-like', their still could be some form of life there. I just hope when we first find life it not very advanced because of how stupid we are still.

just 13 light-years away.
Is that all? what are we waiting for, I`m packing already.


This is not really surprising to the likes of many, myself included who believes there is life out there. And as life, I mean life, not necessarily as we know it. Now it has been found, with the way technology is progressing, it will not be long before we are sending crafts to make some form of contact (if they are not doing it already ), or should I say, it will not belong before we have some form of contact?
In an ideal World a law would be passed were NO guns were allowed and all those out there destroyed, trouble is the law makers are not going to take a risk of trying to pass that without making sure they are armed first.

Why do we have to find these planets anyway? Doesn't anyone think we humans have enough problems of our own? Why don't we try and fix our own society and ecosystem's problems before we go and destroy another one?...

Stupid me: I had red dwarfs and white dwarfs confused.  Thanks for the clarification.

Interesting, i bet there are lots of planets out there with humans.
We cant be the only human planet in this hugs universe..

I think you mean other intelligent lifeforms...

If we went to another planet and found other humans, well...

Find it weird that with technology nowadays astronomers could still miss out so many nearby planets...

If you all could see the size of the lady who lives next door to me you'd think that the title of this article makes soooooooooooo much more sense.

I do agree we must take it seriously when it comes to extraterrestrial life.

We do, not sure why anyone would think otherwise.

Around Proxima Centauri? I would not expect something to have a major head-start on us there because It is believed that the Centauri star system formed about the same time as our own Sun at 4.85 × 109 years.

Well we wasted a few billion years; other systems may have evolved intelligence much more quickly.

Agreed, and if Troodon wasnt wiped out in the dinosaur extinction 65 millions years ago, then our planet may well now have an intelligent grey skinned reptillian
race running it. And with 65 millions years jump on us, they couldve been into intestellar travel for millions of years already.

I have a couple of problems with the red dwarf earth-like planet idea.  To be in the comfort zone of such a star, you have to be close to it -- so close that in less than a billion years or so there will be a tidal lock, so that the planet always keeps the same face pointed at the sun.

Also, I understand that red dwarfs are far more prone to violent flaring and that such flares are much worse than on the sun.  If my understanding here is right, doesn't that kinda make all this talk about so many earth-like planets being so close to us a bit (actually way) premature?

Not all red dwarf stars are prone to flaring. Even in those that do, their severity seems to be linked to their size. Those at the high end of their mass scale are less a problem in this regard. It has also been discussed that a dense atmosphere, and strong magnetic field might protect some such planets from too extreme effects of flares.
The main problem with tidally locked planets, seems to be the accumulation of heat on one side, and the freezing of the opposite. It appears possible that powerful convective cells of winds, or the heat distributing effects of oceans, or both, might make substantial portions of such planets livable. They could transport heat from the hot side to the cold side of these planets, moderating the temperature extremes to a substantial degree.
There is also the possibility of terrestrial-sized moons of a Jovian planets near a red dwarf. Some of these moons would also be in the star's habitable zone. Their 'day' would be the period of the moon's orbit about the planet. This could be a fairly rapid cycle-- on the order of several Earth days.
By the way, Proxima Centauri is about 280 million years older than our Sun. Supposing that the flares' effects on a planet of this star are not too severe, life could have had a 280 million year head start on us. I wonder how far we will have evolved in another 280 million years.
