And it"s in the habitable zone too, road trip anyone?

If there is life there, we wont find it by telescope.

--Personally I always took the fact that we have *never* been visited by an extraterestrial race as proof that there *is* intellegent life out there...

[quote]Gleise 581g`s orbit is only 37 Earth days long. Also, it`s in a tidal lock with Gleise 581, meaning that one side is day, and the other is night all the time. The day side would have scorching temperatures, while the night would be frigid. The only habitable zone of the planet would be the thin strip of twilight zone.[/quote]

That would almost certainly rule out terraforming it. Even if we could, we`d have to create an entire ecosystem of plants and animals that could function in permanent twilight without seasons and feed humans. Could we even get a suitable atmosphere? The temperature differential between dayside and nightside would be pretty extreme and constant - what would that do to weather?

"Lets call the planet "Hera" (After the Greek queen of the Heaven, wife of Zeus)"

or we could call it Eileithyia....the greek god of relieving birth-pains....

look out adlin...your perky boobs seem to be about to be pervtacked by hamman1!

i would agree with planet vulcan but that name has already been applied to a hypothetical planet in our solar system in the 1800s and then again in the 70s

"...don`t you think we should give it a proper name?"

Agreed, I propose Vulcan.

very cool. although the article doesn`t mention if the orbit is always in the inhabitable zone— that`s the turd in the punchbowl for most of these planets, that their orbit is too elliptical (or oval shaped) so half the time they are freezing and the other half of the time they are in `the habitable zone`, making life impossible.

Since Gliese 581 is now such an important star system, being a possible candidate for life, don`t you think we should give it a proper name?

Ya the Swiss, French and Portuguese made this discovery in 2007 it looks like. Mainstream media in the states didn`t think it was news worthy unless they found it, I guess. Lame

Whoever gets there first gets official dibs, so I vote IAB makes a spaceship out of beer cans and duct tape and we set off.

Wasn`t Gliese 581g discovered to be habitable to life about a year ago?

>>mass meant size/weight, NOT GRAVITY. <<<


Mass means mass, the amount of something, it does not change with location.

The gravitational constant is proportional to mass and inversely proportional to the square of the distance.

[quote]You are wrong.

They are wrong, but you are wrong too.

Mass is not weight. Mass is a measurement of the quantity of matter. Weight is a measurement of the force acting on a mass. People slop the two together in common usage, but they`re actually different things.

So, for example, a person with a mass of 70Kg who is standing on the surface of the Earth will have a weight of about 685N towards the centre of the Earth.

[quote]last time i checked mass meant size/weight, NOT GRAVITY.

correct me if i am wrong.[/quote]

OK, I will.

Mass does not mean either size, weight or size divided by weight.

Gravity is a function of mass, so although mass isn`t gravity it is very strongly related. More mass = more gravity.

Trello isn`t necessarily right either, though. Gravity on the surface of a body would depend on the body`s mass *and size*. If I recall correctly, it`s an inverse square law. So a planet 4 times as massive as Earth and with a radius twice as large would have the same gravity on the surface. Something like that. Probably.

You are wrong.
Mass is weight.
Volume is size. (more or less)
Density is mass/volume.

IMO every time a new planet is discovered...we should send a probe in its general direction.

Sure we wont get any information for quite a while and the cost would be enormous, but every new probe we would get better at it and it would eventually improve our rockets and our way of life.

I also think that if we had hundreds of probes going out into space it could act as a network and actually improve the speed of the data we receive. Like right now, if we sent a single probe to a planet, and it takes 20 years to get there, it would prolly take another 20 to get the information but if the data was sent to other probes closer to Earth across the network..something that would take 20 years could be shortened to a year or two.

Gravity is mass `A` times mass `B` / distance squared. A planet 4 times as massive will make your weight 4 times higher. Your weight is the measure of the earth`s gravity on your mass. I doubt any person would have the bone structure or muscle strength to even stand on a planet 4x as massive.

"Now if we could just defy the laws of relativity and fly at the speed of light for 20 freaking years. Yeah I could see those leaping for that chance. All the mere time (no pun) that we don`t slam into a small space rock. Get blasted by a lethal dose of radiation or have a major system malfunction. We can`t even sustain a reliable shuttle system without one falling apart every decade. Going to another planet is going to take a monumental effort in leaping forward in technology for just a few to spread our seed. "
By the time we can do this our civilization will be thousands of times more advanced than ours. It`s either that or we basically kill ourselves first.

We don`t understand gravity very much yet. All we really know right now as to how it works is that the gravitational pull of an object increases with its mass.

Get real. Even if it`s earth like in appearance it still may be more hostile in environment than we are evolved to live in for our own planet alone.

doesn`t the gravity depend on the core of the planet? like iron vs some lighter metal? I don`t know... all I know about science I learned on Star Trek so I think they could handle it. :)

@trello- The solution is simple: we just blow 3/4 of the planet into smithereens using nukes, and live on the remaining chunk of spacerock.

MY PLAN HAS NO FLAWS AND WILL BEGIN TOMORROW

/sigh

Why did I read the comments on that...somewhere in the back of my mind, I thought, "It`s TIME magazine...there are going to be some really insightful comments I bet."


Of course, it degenerated into a religous conversation...one guy actually reminded me of the evolution and jar of peanut butter video that was posted recently.

Problem is that the mass is 3-4 times that of earth. Any human visiting would be 4 times as heavy due to the change in gravity, & doing something as simple as jumping would lead to broken bones.
Still, as far as finding potential alien life outside of earth, it`s a great contender!
