• Habitable planet may not exist

[quote=Science Mag]Two weeks ago, U.S.-based astronomers announced the discovery of the first Goldilocks planet circling another star: just the right size and just the right temperature to harbor alien life. But yesterday at an exoplanet meeting in Turin, Italy, Switzerland-based astronomers announced that they could find no trace of the prized planet in their observations of the same planetary system. All the excitement has been over the subtlest of wiggles in the motion of the star Gliese 581 that lies just 20 light-years from the sun in the direction of the constellation Libra. A consortium of institutions led by the Observatory of Geneva in Switzerland had already discovered four planets circling Gliese 581 by sorting out the subtle motions of the star that are induced by the gravitational tugs of any orbiting planets. On 29 September, a U.S.-based team led by astronomer Steven Vogt of the University of California, Santa Cruz, announced that it had discovered a fifth planet. The American team used a combined set of observations: One 11-year-long set consisted of 122 measurements made by the team, while the other set was 4.3 years long and consisted of 119 measurements published by the consortium. Designated Gliese 581g, the new planet has at least three times the mass of Earth—large enough to hold on to a watery atmosphere—and orbits at a distance from its star that would allow any water to remain liquid. That would make 581g a happy home for life as we know it. But at this week's Astrophysics of Planetary Systems meeting, astronomer Francesco Pepe of the Geneva Observatory and the Swiss group reported that he and his colleagues could find no reliable sign of a fifth planet in Gliese 581's habitable zone. They used only their own observations, but they expanded their published data set from what the U.S. group included in its analysis to a length of 6.5 years and 180 measurements. "We do not see any evidence for a fifth planet ... as announced by Vogt et al.," Pepe wrote Science in an e-mail from the meeting. On the other hand, "we can't prove there is no fifth planet." No one yet has the required precision in their observations to prove the absence of such a small exoplanet, he notes. Astronomer Paul Butler, a member of the U.S. team who is at the Carnegie Institution for Science in Washington, D.C., says he can't comment on the Swiss work because he wasn't at the meeting and the data are unpublished. He notes, however, that more observations will likely be needed to solidify the existence of Gliese 581g. "I would expect that on the time scale of a year or two this should be settled."

Awwwm that sucks. I bet it'll be 100 years before we find any habitable planet.
I'm gonna start a company called Weyland Yutani, we will Build Better Worlds just you wait!
[QUOTE=Amic;25383982]Awwwm that sucks. I bet it'll be 100 years before we find any habitable planet.[/QUOTE] It'll be 200 before we can pull an accurate date out of our ass.
I hear this theory, that theory. All say something different. Some say there's radio signals being sensed somewhere in the universe. Some say they found a planet that could harbor life. Now you tell me that a habitable planet may not exist. Fuck it then. I want proof. All they're saying is :words:
God damnit space, make up your mind already
This friggin planet is a joke. It's twice to thrice earths weigh. People COULD NOT live there permanently, no matter what the temperatures are like. And it's also 20 light years far. That's a ridiculous. We don't have any chance of getting there, even with mutli-generation ship.
never say never

Think of the disappointed War Generals, they can't have their bug-alien wars now!
I heard the UN appointed a Space Ambassador.
[QUOTE=Canuhearme?;25385664]You'll need a company to supply those worlds, I'll ironically call it Blue Sun because Gliese is a Red Dwarf.[/QUOTE] You renegade!
I had a feeling it was a lie for money.
Ill make a company that will build a planet from scratch. Then ill launch it into your planets.
[QUOTE=FoxMeister;25385897]I heard the UN appointed a Space Ambassador.[/QUOTE] I remember that from a thread around here somewhere... Alot of "shit's" been floating through space nowadays.

Wow, that is really Chinese for blue sun.
Who would have guessed?
I guess Destiny is searching the wrong planet.
So no Pandora? ;(

[QUOTE=aurum481;25395024]So no Pandora? ;([/QUOTE] If all goes well there never will be, and if there ever is, we will orbitally bombard the son of a bitch until the surface is nothing but glass and you can see the core glowing inside it.

Do none of you understand how gravity works? Three times the mass with the same volume means you weigh three times as much. Weigh 150 lbs? Now you weigh 450. The human heart simply cannot withstand that kind of pressure over any sort of period. Moreover it isn't even normal weight. Rather than fat being packed on and compressing your organs, EVERY MOLECULE in your body is now being pulled down at three times the force. Your heart, assuming it can keep you alive for more than an hour or two under such stress, would give out extremely quick. Your entire body would need substantial biological or mechanical modification in order to be able to withstand gravity on this planet. A HABITABLE PLANET IS INCONCEIVABLY RARE. Space colonization, barring some ridiculous advances in technology and total planetary terraforming, will predominately need to be done using space stations in orbit around resource hubs. Space stations can mine for materials to fuel themselves as well as potentially mimic near perfect earth gravity and conditions.
I don't really want to move to another planet, this one is okay for now.

Media and wanna be science kids go all like HURRR, HABITABLE PLANET, MAN THE SPACESHIPS, WE ARE MOVING TO ANOTHER PLANET, while it's pretty much useless for us.

It was more about them creatures that might be living there.
