Kako li izgleda venerijanski ječam i hmelj. Pa još kad se to natopi u H2SO4. Samo, da bi pri tom pritisku pjenilo, morali bi dodati malo pur-pena.

Posto sam dosta citala o toj planeti ( Gliese 581), da vas ispravim, njen precnik je 2x veci od Zemljinog, a po svemu sudeci postoji voda na njoj. Verujem i NASA strucnjaku koji je rekao da kada bi postojala mapa planeta za istrazivanje ( zivog sveta na njima )- ova bi bila obelezena velikim X.

Naravno...eko sistem je slican zemljinom, citao sam cak da je jaaako slican.

Da mio lepo uperimo antene tamo, mozda uhvatimo nesto sa njihovog ekvivalenta Exit-a ili Beer festa.

WASHINGTON – Astronomers say they have for the first time spotted a planet beyond our own in what is sometimes called the Goldilocks zone for life: Not too hot, not too cold. Juuuust right.
Not too far from its star, not too close. So it could contain liquid water. The planet itself is neither too big nor too small for the proper surface, gravity and atmosphere.
It's just right. Just like Earth.
"This really is the first Goldilocks planet," said co-discoverer R. Paul Butler of the Carnegie Institution of Washington.
The new planet sits smack in the middle of what astronomers refer to as the habitable zone, unlike any of the nearly 500 other planets astronomers have found outside our solar system. And it is in our galactic neighborhood, suggesting that plenty of Earth-like planets circle other stars.
Finding a planet that could potentially support life is a major step toward answering the timeless question: Are we alone?
Scientists have jumped the gun before on proclaiming that planets outside our solar system were habitable only to have them turn out to be not quite so conducive to life. But this one is so clearly in the right zone that five outside astronomers told The Associated Press it seems to be the real thing.
"This is the first one I'm truly excited about," said Penn State University's Jim Kasting. He said this planet is a "pretty prime candidate" for harboring life.
Life on other planets doesn't mean E.T. Even a simple single-cell bacteria or the equivalent of shower mold would shake perceptions about the uniqueness of life on Earth.
But there are still many unanswered questions about this strange planet. It is about three times the mass of Earth, slightly larger in width and much closer to its star — 14 million miles away versus 93 million. It's so close to its version of the sun that it orbits every 37 days. And it doesn't rotate much, so one side is almost always bright, the other dark.
Temperatures can be as hot as 160 degrees or as frigid as 25 degrees below zero, but in between — in the land of constant sunrise — it would be "shirt-sleeve weather," said co-discoverer Steven Vogt of the University of California at Santa Cruz.
It's unknown whether water actually exists on the planet, and what kind of atmosphere it has. But because conditions are ideal for liquid water, and because there always seems to be life on Earth where there is water, Vogt believes "that chances for life on this planet are 100 percent."
The astronomers' findings are being published in Astrophysical Journal and were announced by the National Science Foundation on Wednesday.
The planet circles a star called Gliese 581. It's about 120 trillion miles away, so it would take several generations for a spaceship to get there. It may seem like a long distance, but in the scheme of the vast universe, this planet is "like right in our face, right next door to us," Vogt said in an interview.
That close proximity and the way it was found so early in astronomers' search for habitable planets hints to scientists that planets like Earth are probably not that rare.
Vogt and Butler ran some calculations, with giant fudge factors built in, and figured that as much as one out of five to 10 stars in the universe have planets that are Earth-sized and in the habitable zone.
With an estimated 200 billion stars in the universe, that means maybe 40 billion planets that have the potential for life, Vogt said. However, Ohio State University's Scott Gaudi cautioned that is too speculative about how common these planets are.
Vogt and Butler used ground-based telescopes to track the star's precise movements over 11 years and watch for wobbles that indicate planets are circling it. The newly discovered planet is actually the sixth found circling Gliese 581. Two looked promising for habitability for a while, another turned out to be too hot and the fifth is likely too cold. This sixth one bracketed right in the sweet spot in between, Vogt said.
With the star designated "a," its sixth planet is called Gliese 581g.
"It's not a very interesting name and it's a beautiful planet," Vogt said. Unofficially, he's named it after his wife: "I call it Zarmina's World."
The star Gliese 581 is a dwarf, about one-third the strength of our sun. Because of that, it can't be seen without a telescope from Earth, although it is in the Libra constellation, Vogt said.
But if you were standing on this new planet, you could easily see our sun, Butler said.
The low-energy dwarf star will live on for billions of years, much longer than our sun, he said. And that just increases the likelihood of life developing on the planet, the discoverers said.
"It's pretty hard to stop life once you give it the right conditions," Vogt said.

Isto, samo na srpskom...

Otkrivena planeta nalik Zemlji

Astronomi su otkrili novu planetu koja verovatno ima vodu i atmosferu, i na kojoj je veoma moguće postojanje života, prenosi britanski “Gardijan”.


Ilustracija planete Gliese 581 g

Planeta nazvana Gliese 581g otkrivena je kako kruži oko zvezde poznate pod imenom Gliese 581 u sazvežđu Vage, a uslovi na njoj su takvi da astronomi smatraju da skoro sigurno postoji neki oblik života na njoj.

Gliese 581 g ima masu trostruko veću od zemlje, a godina na njoj traje 37 dana.
Astronomi veruju da se radi o stenovitoj planeti koja ima dovoljno jaku gravitaciju da bi oko sebe imala atmosferu.

Radi se o prvoj planeti otkrivenoj izvan Sunčevog sistema, na kojoj su uslovi veoma slični uslovima na Zemlji.
Ona je udaljena od Zemlje samo 20 svetlosnih godina.

“Naša istraživanja su pokazala da se radi o planeti na kojoj može postojati život. Činjenica da smo uspeli tako brzo da detektujemo ovu planetu koja je veoma blizu našeg sistema ukazuje na to da se radi o veoma bitnom otkriću”, izjavio je Stiven Vogt, astronom sa univerziteta u Santa Kruzu u Kaliforniji.

Ukoliko dalje istraživanje potvrdi pretpostavke naučnika, to će značiti da je izvan Sunčevog sistema pronađena prva naseljiva planeta.
Astronomi su do sada pronašli više od 400 egzoplaneta (planete izvan našeg sistema), ali su većina njih “negostoljubivi džinovi” poput Jupitera.
Planeta se nalazi u takozvanoj “Zlatokosinoj zoni”, odnosno orbitira u određenom delu oko zvezde tako da temperatura na površini nije ni preniska, ni previsoka.

Prosečna temperatura na planeti varira od -31 do -12 stepeni celzijusovih.
Jedna strana novootkrivene planete je uvek okrenuta ka zvezdi, kao što je jedna strana Meseca uvek okrenuta ka Zemlji, a naučnici smatraju da bi za život najpristupačnija mogla da bude zona između osvetljene i tamne strane.

Ma nisam ni ja preveo nego sa Blica...

A što se tiče susreta...joj...jedva čekam, makar nas sažvakali i posle ispljunuli (u šta sumnjam, ipak smo mi fenomen u ovoj galaksiji)
