Thread: First Planet in Habitable Zone Confirmed

Planet confirmed that could have water – Light Years - CNN.com Blogs

Sweeeet.

I just can't wait until we are able to actually get to other planet and go see ourself. I am really hoping that we advance medice quick enough that people will have vastly larger life spans, so that it is possible.

We also need a fuel source to travel 600 light years, and be able to travel near (or beyond) the speed of light while keeping said people alive and sustained for that many years... the ship itself would take such huge quantities of resources for fuel, living requirements, etc...

I'm not saying it's impossible, but it's highly improbable without resources (plus China is stockpiling all of the precious metals they can to be used for energy production, solar cells, wind turbines, etc.) It would be a neat idea, though.

I seriously hope you guys don't do this.

Well the two ways that I see it as being possible would be either freezing yourself, or you upload your mind into a computer. Obviously both takes technology we don't have. However if a person became a robot or uploaded their mind into a computer or something of that nature, they could turn themself off and use no energy and then turn themself back on when they reach the destination. Or if we prefected cryonics you could freeze yourself, and space is cold enough that you don't need power to remain frozen, then when you arrive you could unfreeze yourself.

The cryonics approach is probably easier technology wise. Of course finding a way to bend space for faster than light travel is a much nicer way to travel. Either way, I don't think it will happen in my life time unless they drasticlly increase human life spans within my life time. Then my life time might be far longer and it may be possible. Which is my hope.

Fuel as in energy... for which to keep systems aboard the ship running... I presume you cannot use solar power, since you'd be traveling outside of star systems...

Take, for example, the humble aluminum can; the paint and lining do not recycle, yet they are mashed and melted and molded with the aluminum, causing it to lose purity. You can't RE-cycle it, you have to DOWN-cycle it, and use it for a lower-grade product. Unless people start designing products to BE recycled, it won't save the planet. We seem to forget Recycle's two best friends, Reduce and Reuse.

Why is everyone talkin bout ships? We have stargates.

What?

On a generation ship, everything would be built to be recycled. Meaning you aren't sitting on a million tons of rations that will be depleted. The ship simply becomes a miniature earth for a few hundred years.

There are alternatives. Bussard ramjet, laser proulsion, anti-matter catalyzed fusion.

Project Daedalus estimated in the late 20th century that it would take a minimum of 50-100 years at ~10% of the speed of light to reach the furthest possible star system (15 light years). Not to mention the design for the fusion-powered plasma jet was about 4 times the size of the empire state building.

Good luck wit dat 600 light years.

Meh, they really know nothing about the planet. It receives roughly the same amount of sunlight as Earth, but it's probably not remotely like Earth. It could have no atmosphere and be freezing, it could have no water on it, it could have a runaway greenhouse effect like Venus, it could be made of gas...

Good to see the technology for planet searching getting steadily more advanced, but there's still some way to go before it's useful.

Of course.

"Rumors of our scientific achievement have been blown greatly out of proportion." - People who found a planet over twice the size of earth a certain distance from a star.

There's a difference between negativity and living in the real world.

Most people who I've heard talk about this story seem to think they've found literally found a planet with oceans and life. This isn't helped by the bloody ridiculous 'artist's impression of the planet' that accompanied the press release which is basically covered in forests.

I can't wait until a habitable planet is found. I just have the sanity to not celebrate the discovery of what is likely a hellish lump of rock as said planet.

We need more advanced ways of magnification- better, keener, observier.

Wouldn't it be weird if we ended up being alien invaders?

Two words: Generation Ships.

One more: Recycling!

The planet is even more mysterious because its radius is between that of Earth and Uranus and Neptune, both of which have radii about four times the size of Earth's. So we don't know what a planet in this size range typically looks like.

"We have no planet like this in our solar system," he said.

What the fuck does this mean? I mean, really this makes no sense to me whatsoever.

Also, cool if this is true. Hopefully they find one a little closer though lol
Like maybe 1 lightyear would be nice. As long as we can invent light speed travel lol

As far as I can tell the meaning is quite simple; we know of a few planets smaller than Earth, and a few larger than Neptune, but none in the range in between.

And it's pretty unlikely we ever find any planets within 1 lightyear. I'd bet you £100 against it.

What do they mean they don't know what a planet like this looks like?
It looks like a planet between Earth and Neptune size....

Oh and I know they probably won't find a planet that could sustain life within 1 light year.
I was just sayin', it would be cool. Coz then we could get there in my life time lol

Well that is obvious, the only planets within a light year of us are the ones in our solar system. The nearest solar system to ours is like 4 light years away, there isn't anything between.

The media sure knows how to work a crowd don't they?

pffft.. Scientists claims that they do not yet know if Kepler-22b has a predominantly gaseous, liquid or rocky composition.

But of course they do. Look at all the pictures next to each article regarding Kepler-22b.



I wouldn't mind meeting the person who actually gets paid to Photoshop these these spheres in front of bits of nebulae all day? I can just imagine the conversation.

NASA Engineer: "Hey we just found one and it's a big one! We need you to get right to work on your rendition, like Asap! Shit's going public in 10!
Artist: "So what do you suppose this one should look like?"
NASA Engineer: "Beats the hell out of me, it's 600 freakin light-years away. How the @#$% should I know!"
Artist: " uh... ok.. I'll just pick a planet from an old Star Wars episode at random then."
NASA Engineer: "Ok, yea you do that, but hey! No funny stuff. Save the stars, rainbows, and unicorns for your acid trips."
Artist: "Nebulous clouds in the background- check."

This is the EXACT conversation I was having with my friend about this planet. They saw a small sphere within the habitable zone. That's it. They know the diameter, and that it's probably the right temperature for water to be liquid (if it even has water.) Buuut everyone is talking about it as if it's a "second earth" (thanks to sensationalist media). For its size it seems likely to be a gaseous planet.


ALSO: I agree. All artistic representations of planets should feature nebulous clouds, regardless of the reality of that sector of the galaxy. It just makes for better photos.
