Water found on Life Friendly Planet

So, considering the grand number of threads that are utterly depressing, combative, or just plain shitstorms, I wanted to celebrate something big in science that just went by. A planet, tens of times larger than earth has been found to have water on it. (No, we didn’t go, it’s through water vapor absorbing light. The article has more info on how that works.) That’s noteworthy, but not overtly so-other planets have been found to have water before. Thing is, this one is in the Goldilocks Zone of its respective star, making it the most likely candidate for life that we know of.

Sadly, we can’t exactly check-it’s 111 light years away. But SPACE!

So, NSG, do you think there might be life on this planet? Would it be worth it to go? Not just for extraterrestrial life, but also as a secondary planet for us? And if there was life, what would happen?

Given it's ten's of times bigger than earth then I assume gravity is ten's of times greater than on earth, meaning it would be likely life would find it difficult to grow over a certain size, or be extremely lightweight and somewhat fragile.

They'll be easy to beat.

Attack!

I personally think colonies orbiting around both the planet and it's Lagrange points would be cooler, but eh what do I know?

Well, what would we want in a habitable planet?

Liquid water
Similar gravity
Nitrogen oxygen atmosphere
Solid surface
Strong Magnetic field
Fertile soil

We know two of those are positive, now all we need is confirmation on the other four...and either an FTL drive or a generation ship.

3, actually. Red Giants are too generally weak to strip magnetic fields, iirc. I could be totally wrong.

[Petrolheadia]

OK, how motherfucking huge will the sum of money necessary to get there be?

[US-SSR]

8x more massive than Earth and close enough to its sun to fry any life via radiation. maybe a water world, maybe a few vapor trails. i won't be booking a trip any time soon.

Actually, according to this it’d be more like 1.42G, so 50% higher then earth.

But it’d also require a magnetic field to start with, for example I think Mars lacks one.

A lot depends on climate conditions which we have no way of knowing, but "lightweight and fragile" seems unlikely. In heavy gravity you're going to run into the same problems that terrestrial animals struggle with as they grow larger, but sooner. So you would expect animal-like life to have the general body plan of a elephant or sauropod on land. With extremely sturdy trunk like legs, even for a creature the size of a small deer.

And, of course, in our gravity they would be absurdly strong. Having many times the bone and muscle mass needed to support themselves.

I myself see herds of pancakes roaming the land, large tasty pancakes.

There's good reason to think that a terrestrial planet's magnetic field is linked to it's size. And that larger planets are more likely to have strong magnetic fields.

It does, just really weak.

But we have no way of knowing whether this planet has an internal dynamo, which determines the strength.

With the minor hitch that going down to get one will cause you to collapse like melted butter.

Although Mars lacks the internal dynamo to generate the strong magnetic field the earth enjoys, it does have areas of dense crust zones that create magnetic bubbles in response to solar winds. SO whilst conditions would be far more volatile than on earth, a planet with similar magnetic bubbles could support small habitable pockets

We can't attack. We'd die because of the high gravity. Or merely lie horizontally in water. Hoping that our hearts don't give out from pumping around blood.

(and yes, I now also see it is a mere 1.42G, which we are quite capable of enduring)

Only a few hours after discovering they have water we've already declared war.

I'll pass. The TV reception is probably terrible, and I can't imagine the internet is very good there either.

Finally some peace and quiet to actually get things done!

[The Huskar Social Union]

Thats fucking sweeeeeeeeeeeeeet


We should claim this world in the name of the Immortal God Emperor of Man!

Does it have oil?

Uranium?

[Heloin]

Does it have oil?

Uranium?

Only if it has/had life.

Probably.

do you think there might be life on this planet? maybe
Would it be worth it to go? someday when we have Star Trek type spaceships.

This is amazing

A pancake would never do that.

Exactly 85 gazillion ChF, adjusted for future inflation.
