Study: At least 17B Earth-size planets

Astronomers estimate one in six stars in our Milky Way galaxy has a planet the size of Earth orbiting it.

It's not just the size of these other planets. It's also their distance from their star(s) and the type of star(s)(how hot they burn) that they rotate around.

The optimum distance from the type of star(s) these planets rotate around is known as being "in the Goldilocks zone" (not too hot...not too cold), as I recall.

Let's face it, it's a dream and we are not going to get there anytime soon unless we terraform Mars.

Wonder how the real estate boom will go? lol

Even if it were the right size and right temperature range, that does not necessarily translate into being inhabitable. The same size does not always mean the same density which can effect the degree of gravitational pull as well. Our planet may indeed be the only inhabitable planet in the universe for life as we know it.

I am sure you meant habitable there..just sayin'

but regardless...

We are going to really be lucky to ever know if we are not alone in this...which is why we should really be treating the whole thing a bit better...

Oo.... um no way. lol
How could you say that!? Even conceive the idea when we see less then 10 percent of the sky!?

BTW Hi hello. Nice to meet you.

I only intended this as a possibility and not anything definite. To sustain life as we know it, we need the right atmospheric composition, the right blend of elements and compounds, conditions favorable for precipitation, The right medium to grow plants, the right temperature, and the right gravity just for starters. Life on other planets? Possible, but I am not counting on it.

My son has done that. But he's having a bit of trouble getting a ride back to Earth.

Pretty well, I think. Starbucks is already investing in site selection.

Maybe we can set one up for the 'muslim extremists' so they have their own little pure, infidel free place to pray to Allah all day long if they want.

With millons of galaxies, we can 't just be the only life of this immense universe.

Just think, humans could be the duckbilled platypus of the 'sentient beings universe'.

[Tiger Lilly]

17 billion, we had better start naming them now....it's going to take awhile and if we leave it up the the scientists they will just have a lot of stupid names full of numbers.....

GOT THAT RIGHT!! Look at ALL the different cultures of the Earth. WHY do Asians have slanted eyes and Afro-Americans are dark skinned? Ever wonder WHY each one of us was born in said Country??

[Old Sam]

...reckon all 17B places have politicians as goofed up as ours?.......or are as PC as this poor country is?.....

[winfredable]

scientists are very curious to find planet like our.

I don't think we need any more Subaru driving lesbians and queers or Birkenstock wearing wifi liberals in the Universe. Thet're already plenty abundant here on Earth.

To make them feel at home,,,, I think Mars would be perfect in topography and temperature.
