"We've found it! we've finally found it!! A planet with Life, Liquid water and intelligent life! Do you know what this means?!" *Looks out the window, then turns around* "BEER!"
Studies indicate the planet is situated near the middle of the habitable zone of its parent star, where temperatures are neither too hot nor too cold to sustain earth-like life. If it is a rocky planet, favorable atmospheric conditions could permit the presence of liquid water, a necessity for most known life, on its surface. With a mass 3.1 to 4.3 times Earth's, Gliese 581 g is considered a super-Earth and is the planet closest in size to Earth known in a habitable zone.
@joncl1 I think I understand: Yes, gravity's force does fall off as you recede from the mass creating it, and density determines many different properties of how the force of gravity distributes itself around the object. Hence the disparity in gravity's behavior around our gas cloud and mini-black hole. I hope I've answered your questions adequately.
@joncl1 No. An event horizon is a spherical region around a superdense object where the escape velocity exceeds the speed of light, hiding the object behind it forever since no light or matter can ever escape it. It is this phenomenon that makes black holes "black". If you're at the surface of the cloud, much of the matter is far away and pulls you less, if you touch the previously mentioned object, all the matter is close at hand and can pull on you with it's full force.
@LordSlag I'm saying the effect of event horizons scaled down on levels the further away you get from the center of the density in the mass. Not actual event horizons. That's why I said "it's like"
@xmangosaintx Hello again! Like I said, antimatter has been found in the microscopic quantum level in CERN and in other labs. However, the quest to build an antimatter Ion - propelled spaceship, is beyond current technological standards. Cheers.
i think life in the universe is a matter of combinations. you get a proper star to provide heat, and a proper planet at the right distance, and there is potential for life. of course there is more to it, but when you consider the size of the universe, the possibilities are almost infinite. for instance, if you want to get a glimpse of perspective... check "vy canis majoris", the largest start known to man. but even it is nothing relative to the universe itself. fascinating stuff indeed.
For those who keep asking about how they know if it a rocky planet or what... u sure need to watch or read more about the universe... the explaination is easy... U can ether break up the light... or messure it when it passes it's sun...
@Bigjakestudios there are four proven planets currently. due to lack of data, we just don't know how many there actually are, but the data we have right now suggests that there might be an additional two.
@skimowhite586 simple arithmetic shows that assuming that the planet is as dense as earth, (not an entirely unreasonable assumption) the gravity on the surface would be, I think, though I am quite tired and something tells me I may have made a mistake, 2.83 times the earth's gravitational pull.
@UNSCful What are you talking about, Gliese 581 D is on the verge of the habitable zone, it's further than Gliese 581 G... Gliese 581 D would be equivilent of mars on terms of habitabilty. I would have to say if i compare the two, Gliese 581 D would range from -80 celsius to -30 celsius min.
@joncl1 I don't know why I had to unspam your comment above but, oh well. Gravity IS proportional to mass but local effects change with density. It's the difference between being at the surface of a huge gas cloud with one solar mass and touching an object the size of a molecule with one solar mass. The gas cloud will slowly accelerate you towards it's center of mass while that tiny black hole will crush you through it's event horizon one subatomic particle at a time.
@joncl1 8X the mass doesn't mean 8X the gravity of Earth since it doesn't take into account it's density and the force of gravitation at the surface is also dependen upon this value as well. It might be more, it could be less. Also, "The Habitable Zone" refers to a band of orbits around the star where temperatures are conducive to the existence of liquid water, not that a planet is automatically livable by humans. Still....intriguing.
@maxinator53 just for the record, some people say that something bad will happen because the Sun, The Earth and the center of the Milkeyway will be aligned, and they WILL be on december 21 2012. What they forget to mention is that this happens every year on december 21st... actually also on june 21st, but that's besides the point. *smile*
Gliese 581 apparently doesn't rotate like the Earth and we need to find out if it has a moon. If it does, it must of been captured. If only one side always faces the sun, the always dark side must be solid ice. This was a good milestone for astronomers, but we need to keep looking.
@skimowhite586 Unles smy maths is incorrect, (as it was in my earlier comment), the gravitational pull would be about twice that of the earth, for a planet 8 times the mass. Actually, the minimum mass for gleise 581d is about 5.6 earth masses, so the gravity may well be lower still, about 1.78 times earth's.
why is everyone all like "naw the planet will get destroyed humanity sucks." As far as we know, we have no precedent. So whatever, we're terrible. We use resources, we kill for resources, we often abandon the moral codes we set for ourselves. But my god, does the universe have any better? We are something unlike anything else, even if there are other lifeforms out there or on Gliese. Don't we want the universe to know that? To make a richer and more knowledgeable life for future generations?
"But there's another one, about 8 times the mass of earth..." Too bad we can't go there. Everything would weigh 8x as much as it does on Earth. So if you weigh 200 lbs, over there you'd weigh 1600 lbs. You be crushed by your own weight.
@coolair00 I don't think the gravity is going to be that strong. The planet has 8x the size of Earth, that means 2x the diameter. The gravity would be 8x stronger AT THE SAME DISTANCE, but since you're twice as far away from the core, that number decreases by factor 4 (gravity is reversed proportional to the square of distance). So in the end, you'll only have 8/4=2g's, which is still very uncomfortable, but endurable. But again, the chance of actually finding life there is quite low
I am 18 and we barely got a robot to mars. I see more shit happening on Earth and it seems like its pulling humanity back. One step forward and two steps back, I dont think I'll get my hopes up on witnessing this planet in my life time or generation.
Now having said all that (wiki) , 3 to 4 g's would be very rough. Imagine a 180 lb person on this world wieghing 600 to 700 ilbs. Simple rocks would be very heavy. If there is a civilation that is humanoid, they would possibly be very short and strong, as a fall would likely kill a human.
@LordSlag I'm saying that the further away you get from the center in density of mass, irrelevant to the volume, you encounter decreasing effects of gravity. Like a black hole event horizon there's levels of gravity. The event horizon describes the level of gravity matter cannot escape. I'm using that ideology reduced by orders of magnitude as you get further away from the center of density in volume of mass
@EvilMatty12 Oh I'm certain we'll try at some point. Humans are curious explorers and the instant it becomes feasible to explore other stellar systems with probes or, dare I hope within my lifetime, manned missions: We WILL! :)
Lets go buy property now for our great,great,great,great grand children to thrive there where they can thank their grandparents ahead of time buying a land on another planet. Yea!!
@xmangosaintx You see? It's all Relative. It took 4 months for you to reply, whereas I do in 30 minutes. Which means I am about ~5000 times faster. That's an analogy that can apply to conventional spaceships that currently fly with 5 miles per second, to boost them 5000-fold by wrap antimatter beams in order to reach 25 thousand miles per second which is nearly 2/15 of the speed of light. Thus I need 'only' 150 years to get there, that can be bypassed by hybernating myself in cryo-preservation
common there is more patern for life then the Earth form of life, that narrow way of thinking really close possibilities of finding new life form even on earth
There is no doubt there is life maybe not that far form earth (20 years light) but... it is a pity we will probably never be able to reach that distance. Maybe throw some satellite right now and receive some pictures of that planet 500 years later.
the biggest country in the world if one colonized gilese581d... anyways... im pretty sure that gilese 581d would be able to hold about 5 times as more people on the planet instead of earth.. so lots of small countries in the planet... i wonder what mineral is in there... and life?... wow this discovery makes me want to be a scientist and/ or astronomer
@Neueregel sorry man not that easy even if their was intelligent life on that planet we still don't know if their is a necessary amount of oxygen for us to live
and when exactly did I say there was something wrong with learning? If it was up to me, I'd fund NASA just for the hell of it cause I like the discoveries they tell us. But average people need reasons to spend money like that other than just "For curiosity's sake" I was pointing out to him the benefits of simple curiosity
Why do we want to screw other planets when we aren't even able to live in peace in this one because of our own greed? Oh... because of our own greed. Now I get it.
well it sounds cool BUT what the point? we won't be able to find out more till the yr 3000. & not even attempt to visit it till yr 5000 & its gonna take how long to travel 120 trillion miles?! way too LONG!. I would LOVE to see what it looks like & what in store for mankind, but unfortunelty we won't ever see it.
"We've found it! we've finally found it!! A planet with Life, Liquid water and intelligent life!
Do you know what this means?!"
*Looks out the window, then turns around*
"BEER!"
@Helge129 did you measure that by diameaatater what ever its spelled diameter or volume
Studies indicate the planet is situated near the middle of the habitable zone of its parent star, where temperatures are neither too hot nor too cold to sustain earth-like life. If it is a rocky planet, favorable atmospheric conditions could permit the presence of liquid water, a necessity for most known life, on its surface.

Hence the disparity in gravity's behavior around our gas cloud and mini-black hole. I hope I've answered your questions adequately.
@xmangosaintx Antimatter has been found on laboratories. The technology to use it on spaceships is not available yet though
yeah i have heard from different doco's that it was 2 times the mass of earth in the habital zone or goldilocks
@joncl1 No. An event horizon is a spherical region around a superdense object where the escape velocity exceeds the speed of light, hiding the object behind it forever since no light or matter can ever escape it. It is this phenomenon that makes black holes "black". If you're at the surface of the cloud, much of the matter is far away and pulls you less, if you touch the previously mentioned object, all the matter is close at hand and can pull on you with it's full force.
@joncl1 I was happy to help increase your understanding. :)
@LordSlag kk thanks.. lol was just a joke any way... but some time will we be able to reach futher planets or are we never gonna try?
In how the universe works... Which episode is this?
can we get an update on the gliese 581?
@LordSlag I'm saying the effect of event horizons scaled down on levels the further away you get from the center of the density in the mass. Not actual event horizons. That's why I said "it's like"
wow... sometimes you forget how cool astronomy is
@Genomaza9 Wrong. The surface-gravity of a celestial object also depends on the diameter. 8x mass doesn't mean 8x gravity if it's bigger.
@xmangosaintx Hello again! Like I said, antimatter has been found in the microscopic quantum level in CERN and in other labs. However, the quest to build an antimatter Ion - propelled spaceship, is beyond current technological standards. Cheers.
instaBlaster
@Azza1070 I care, where can I get that?
i think life in the universe is a matter of combinations. you get a proper star to provide heat, and a proper planet at the right distance, and there is potential for life. of course there is more to it, but when you consider the size of the universe, the possibilities are almost infinite. for instance, if you want to get a glimpse of perspective... check "vy canis majoris", the largest start known to man. but even it is nothing relative to the universe itself. fascinating stuff indeed.

@Bigjakestudios there are four proven planets currently. due to lack of data, we just don't know how many there actually are, but the data we have right now suggests that there might be an additional two.
Earth would win a beauty contest, hands down!
What is the other pattern for life?
@skimowhite586 simple arithmetic shows that assuming that the planet is as dense as earth, (not an entirely unreasonable assumption) the gravity on the surface would be, I think, though I am quite tired and something tells me I may have made a mistake, 2.83 times the earth's gravitational pull.
Great! now only left to discover are there any life forms on thaty planet!
@UNSCful What are you talking about, Gliese 581 D is on the verge of the habitable zone, it's further than Gliese 581 G... Gliese 581 D would be equivilent of mars on terms of habitabilty. I would have to say if i compare the two, Gliese 581 D would range from -80 celsius to -30 celsius min.

@LordSlag similar to the levels of pressure in water / atmosphere as you get closer / further away from to the center of the earth
@LordSlag i understand... it's like levels of event horizons?
@maxinator53 just for the record, some people say that something bad will happen because the Sun, The Earth and the center of the Milkeyway will be aligned, and they WILL be on december 21 2012.

At 1:18 he says there is four planets going around gliese 581. But there is a program called celestia and that says there is 6!
@MetalHeart8787 300 years away from our solar system, so by 3000 we might be able to get there
@ViktorDieZiege
I don't think they actually have proven that, they just speculated what may or may not be.
why is everyone all like "naw the planet will get destroyed humanity sucks." As far as we know, we have no precedent. So whatever, we're terrible.

@patrickledford420 i thought they meant it could be habitable by us...
420 blazing the stars
I know that planet, i went to a rave on it once, best pills i eva had
this video is before they discovered the gliese 581 G.....gliese 581 G was discovered in september 2010 .
@coolair00 I don't think the gravity is going to be that strong. The planet has 8x the size of Earth, that means 2x the diameter. The gravity would be 8x stronger AT THE SAME DISTANCE, but since you're twice as far away from the core, that number decreases by factor 4 (gravity is reversed proportional to the square of distance). So in the end, you'll only have 8/4=2g's, which is still very uncomfortable, but endurable.
But again, the chance of actually finding life there is quite low
If we go 11000 miles every second it would take 70 years to get to this planet :'(
@Ehnzo18 As Mr. Spock would say: fascinating. :-)
I am 18 and we barely got a robot to mars. I see more shit happening on Earth and it seems like its pulling humanity back. One step forward and two steps back, I dont think I'll get my hopes up on witnessing this planet in my life time or generation.
What *I* wanna know is when they're gonna invent a RUclips in which I can scroll through the comments and keep watching THE VIDEO.
@tomsCOOLdancing and you sir are what astronomers call, " awesome! :D "
@mutanTV131
You know that valve can't count to 3
@Boogyman4050 Gliese 581 is the name of the star, and you cant assume it has water
@Fartzine Hmm, it actually is on the news all over the world. I just read it on a Peruvian News Website and came to youtube to find out more.
@InySsaI
lol there are like milion Glieses, it's just a name depending with which tool they discover them.
Now having said all that (wiki) , 3 to 4 g's would be very rough. Imagine a 180 lb person on this world wieghing 600 to 700 ilbs. Simple rocks would be very heavy. If there is a civilation that is humanoid, they would possibly be very short and strong, as a fall would likely kill a human.

The Gliese 581 system lies 20.3 lightyears away from us.
@EvilMatty12 Oh I'm certain we'll try at some point. Humans are curious explorers and the instant it becomes feasible to explore other stellar systems with probes or, dare I hope within my lifetime, manned missions: We WILL! :)
@LaxBboys That truly is our reach.
8 times the size of earth? Guess were still gonna fight for a piece of land...
You mean the 7 planets we know of, and the last one orbits a little further than Venus.
Lets go buy property now for our great,great,great,great grand children to thrive there where they can thank their grandparents ahead of time buying a land on another planet. Yea!!
@Boogyman4050 but when it orbits around the sun the sides switch
let's go.. I already packed my stuff!!
Why do I want to play spore now...
@xmangosaintx You see? It's all Relative. It took 4 months for you to reply, whereas I do in 30 minutes. Which means I am about ~5000 times faster.

@maxinator53 its aligning with the black hole and the sun not the planets
I'M GOING THERE FOR HOLIDAYS! :D
@LordSlag indeed, thank you
common there is more patern for life then the Earth form of life, that narrow way of thinking really close possibilities of finding new life form even on earth
hold on a sec, how far away is this, lets fly to it and see if we can live on it.. ^_^
I wonder what kind of living creature lives there, maybe my future wife ... xD
@KOstriker1 Because that's just not how life works
There is no doubt there is life maybe not that far form earth (20 years light) but... it is a pity we will probably never be able to reach that distance. Maybe throw some satellite right now and receive some pictures of that planet 500 years later.
the biggest country in the world if one colonized gilese581d...

@maxinator53 It's not going to happen. The Mayans believed it was the end of an era, not the end of the World.
an interesting thought..
@Neueregel sorry man not that easy even if their was intelligent life on that planet we still don't know if their is a necessary amount of oxygen for us to live
and when exactly did I say there was something wrong with learning?

I was pointing out to him the benefits of simple curiosity
@skimowhite586 What comment were you replying to? I posted several...
Let''s migrate then!!! I wanna buy property there
The more videos I watch, the bigger the planet is. Last video it was 7 times. a few minutes ago it was 3 times bigger. wtf. Give the right details!
@LordSlag I will say wait 300-400 years and we will be exploring the vast Universe.
how could it be habitable at 8X the mass of earth. That's 8X the gravity. We wouldn't even be able to stand up...
but maybe it so far that when we see it ,its actually millions years ago and now it might be gone
Why do we want to screw other planets when we aren't even able to live in peace in this one because of our own greed?
Oh... because of our own greed. Now I get it.
@Kvnblmr lmao no....definitely not. I can see what you mean though.
Planet Reach?
well it sounds cool BUT what the point? we won't be able to find out more till the yr 3000. & not even attempt to visit it till yr 5000 & its gonna take how long to travel
120 trillion miles?! way too LONG!. I would LOVE to see what it looks like & what in store for mankind, but unfortunelty we won't ever see it.
@Genomaza9 As far as I know, both G and D may support live, although D is the most likely.
i wanna go there... :)
we need a anywhere door....
So if you want to move there, just be prepared to weigh 8 times your weight on earth.
@EvilMatty12 we haven't even made it to mars yet...
@elmalacopa I intended too thank you so much for noticing what i did there Hahaha :)
@skimowhite586 Mars is 0.533 times the size of Earth, and has 0.37 times its surface gravity.
I mean in the outer planet of Gliese 581. Earth is quite saturated :DDDD
@tomsCOOL plus mars has 1/3 the size of earth and thus 1/3 the gravity or its just a coincident.
@pingshiyu That one person lives in that planet, dislike how we earthians found his planet and someday to colonize their land.
Interesting
@AmyK007
Agreed.
@another505 its not millions of years ago its 20.5 light years away...that means were seeing it as it was 20.5 years ago...not millions lol
Science saves earth from asteroids by detecting them and negating them.
2:12 It looks like Planet Reach!!!
