Wasn't another earth like plante already found before this one, and everyone kinda just forgot about it?

Gliese 876 d? Ya. We ignore it now. 'Cause it's HUGE.

There were many planets similar to the Earth. Even certain moons in our local solar system are suitable (Titan, Europa, Triton)

Just Here For The Pie

Isn't one of the moons of Jupiter a host of clean, unfrozen water? I remember talk about that in the 90s.

Hey, you think if humans lived on Earth II (Needs A Cooler Name) that they would learn history of Earth or not? I say nay.

Jupitors moon, Europa has oceans that many believed to be under a massive block of ice, but now believe they are under a massive block of ice and under ground. (If you ask me it sounds a little strange.) Anyway, it supposedly has both oceans of water and of ammonia.

No, they're still under ice. But it's methane ice, not water ice...

a) So nobody really knows if there is a planet here, it's just a guess?

b) It would not be Earth's twin. It might be a similarly sized planet a similar distance from a similar sun. To be a twin, it would need to have exactly the right atmospheric conditions to support life like our special planet does.

c) I'm rather skeptical of the whole "we think life should be here" thing. It's never proved to be the case, and I doubt it ever will.

a) As is the state with every single extrasolar planet. We can only observe them indirectly.

b) True

c) We've never explored somewhere there /should/ be life.
c) We probably never will either. Another reason I'm not a fan of this area of space exploration and astronomy.

Europa.
Oh sorry, I didn't know life was already discovered on Europa. Silly me.

Isn't it more of a conjecture than a discovery?

No, based on the type of star and its distance from the planet, we can pretty much exactly know what it's like.
Maybe we can know what shape or size it is, to a reasonable accuracy. If this is the closest planet to Earth ever "found" though, we don't really have a premise to work off of, besides Earth itself, and there's only one of those.
I just think it's not right to say that it's "Earth's Twin," because that implies so much more than we really know. We don't even know if there's any water there.

Silly me, I forgot to write should. Oh wait? I didn't?! Reading comprehension, smartass.

Water is a wholly insignificant part of Earth's chemical composition, density, and location in the solar system.
I really have no idea what you're talking about with that first statement. Is that in regards to Europa? Please clarify.

Somebody already replied to your water statement.

However, colonization of certain moons on Jupiter are not reccomended as there are strong levels of radiation.
The Saturnian system is a much better place to look, as they do have as intense radiation levels.

Why would the Saturnian system be a much better place to look if it has intense radiation levels?

That it would.

You have to actually consider how much radiation actually gets through the atmosphere of a moon/planet.
*Certain amounts are required in order to sustain life.

Why are people so afraid of radiation? Surely the cold war iodine fiasco in the pacific NW has something to do with it, but most of the fear is entirely baseless.

Oh... awesome. A ship of 20,000 people in Cyrogenic Sleep arrive on a moon of Saturn, Uranus or Neptune only to realize that 95% of the human payload is dead. Welcome to the world of Starcraft my friend. This is not Tarsonis. This is life.

20, 000 x (1.00 - 0.95) = 1000 Survivors
1000 Survivors x (Chance of Cyrogenic Survival) = 1 Survivor.
1 Survivor = Un-reproducable.
= Death
= Pissed of people on Earth.

Duh.

This my friend, is random statistics. We obviously don't live on random statistics.

That depends on the radiation ammount. Hiroshima and Nagasaki population wouldn't probably agree.

Earth itself is being bombarded with solar/UV radiation 60/60/24/7/4/12. What keeps us alive is our good old magnetic field and the atmosphere.
Our solution is an artificial atmosphere and a giant magnet that is similar to the size of the Earth's core. :shifty:

Its an estimate. THink about it. Can we HUMANS survive at this time of age in Cyrogenic Sleep, no, why? ITS NOT INVENTED (or maybe it is, Ill have to look that up). But the chances of a human surviving on such unrealistic levels of radition are unimaginable. Perhaps you do what Hat said and create a giant magnet (somehow...) and it works. Now you have to move that magnet there and hope that the moon orbits well enough that that magnet does not get pulled into orbit by Jupiter. And even before that, HOW DO you get a magnet that big to revolve around a moon?

NudeRaider -- PSA: ASUS apparently decided their RMA department needs to "become profitable" and for a while now outright tries to scam customers. They were called out on it a year ago, promised to change, but didn't. https://www.youtube.com/watch?v=7pMrssIrKcY so my recommendation: Stop buying ASUS, and if you already have and need something RMA'd, make sure to not let them bully you into paying.
