EARTH-LIKE PLANET DETECTED AROUND PROXIMA CENTAURI!!!!!!

It was habitable in the past, where are those aliens?

Sandblasted by several hundred mile an hour winds, assuming that it even has an atmosphere.

Was it? When did the flares start in the star's history?

it's time brothers

Dehydrate dehydrate!

Three body series is a must read. It involves first contact with ayylmaos in the alpha centurai system

WHAT HTE UFCK WHEN IO DGET TO MOVE THERE AND FUCK ALIEN BABES?

...

>confusing 1400 lightyears and 4 lightyears
Like how is that even possible?

>Tidally locked
>Even if it miraculously happens to have decent conditions the red dwarf will constantly fuck the planet with extreme temperature changes that can happen in a matter of minutes

Why are we even scanning red dwarfs? Shouldn't we be focusing on orange/yellow dwarfs?

>But at a distance of 1,400 light-years away, humankind has little hope of reaching this Earth-twin any time soon.
Even if you replace it with 4 light years away it's still impossible to reach there.

Nuclear propulsion sources like fission fragment rockets can do a flyby in a couple of decades after leaving earth. It's a long wait, but it's doable. It would just be like how we're still tracking Voyager even though it was launched in the 70's.

>In comparison, the exoplanet orbiting Proxima Centauri, if confirmed, is just 4.24 light-years away.

>if we make science fiction real we can go there

The technology has been operational and tested on the ground in various forms since the 60's. We just have to send it to space.

Hello retard.

Grays are from zeta reticuli you cucks

Show me the rocket in the working that can travel 4.2 light years distance in a couple of decades in your next post or don't ever come back from

ok everybody stop for a second

what source are they quoting? is it a rumor? is it the 1st of april in some place of the world yet?

How old are you? Are you that idiot that keeps posting that "this is what singularityfags believe" image in inappropriate threads?

kys kiddo

I bet there ain't nothing on that planet, just lifeless rock like Mars. We'll never find any ayylmaos.

Hah. I think he's doing the same thing on /mu/ in Grimes threads.
"this is what grimesfags actually believe"
"this is what grimesfags actually believe"
"this is what grimesfags actually believe"
Every post. Some of the commentary he makes is entertaining and has a some degree of truth though.

"grimesfags actually believe this", rather.

Nah it's some report that's being prepared by the ESA, the news has leaked. Expect a proper announcement and vapid news articles soon.

what I fear is that they'll sell some shitty super earth as "earth like"...

You rang?

Apparently a bunch of billionaires plan to invest in a project that essentially involves flinging space kites with cameras toward AC at approximately 20% the speed of light using some laser shit on the moon. So it would take the kites approximately 20 years to reach the solar system, take pictures as they pass through, and then another 4 for them to transmit the photos back to earth.

>I have a bachelors degree in popsci

the pnly billionaire that is actually delivering is Elon (even if he seems to be heading straight into bankruptcy)

all those others billionaires that invest into space are useless, they all get stuck in the planning phase

oh well.

>his smile and optimism: gone

there are two types of people... xD

Reading it right now.

There was an effort since a decade to find this planet and it culminated in Red Dot search initiative couple of months.
The results are from HARPS.

I am in contact with a very knowledgeable figure in astronomy world and I asked him about it to which he answered "I can neither confirm nor deny". Which means confirmation.
For the record he knew in advance about couple of discoveries.

AYYS CONFIRMED!
AYYS CONFIRMED!
AYYS CONFIRMED!
AYYS CONFIRMED!

We will probably be able to build hypertelescopes in 20 years that will be able to image this planet.

Faggot kill yourself there are plenty of rockets that can do it they just have never been developed.

>Seems, they found a hint to a small deviation of Proxima Centauri's trajectory close to the limits of statistical evidence.
The press tends to make a sensation of exciting preliminary hypotheses. So, let's wait, how statistically significant the findings actually turn out to be.

>Why are we even scanning red dwarfs?
Because "we" aren't trying to satisfy your Buck Rodgers/Star Trek fantasies.
We'll probably never find Earth v2.0 orbiting a red dwarf, but there could be *something* living there.

>Even if you replace it with 4 light years away it's still impossible to reach there.
No distance is "impossible".
We'll be capable of reaching Proxima Centauri long before we reach Kepler-452b, for instance.

how do you answer this

centauri-dreams.org/?p=34157
And what would be the effect of tidal heating on magnetic fields over the aeons? To find out, Driscoll and Barnes used simulations of planets around stars ranging from 0.1 to 0.6 of a solar mass. Their finding is that tidal heating can help by making a planetary mantle more able to dissipate interior heat, a process that cools the core and thus helps in the creation of a magnetic field.

Thus we have a way to protect the surface of a red dwarf’s planet in an environment that can show a good deal of flare activity in the early part of the star’s lifespan. “I was excited to see that tidal heating can actually save a planet in the sense that it allows cooling of the core,” says Barnes. “That’s the dominant way to form magnetic fields.” A planet in the habitable zone of a red dwarf in its early flare phase may have just the protection it needs to allow life.

So we don’t exactly have a panacea that makes all red dwarf star planets in the habitable zone likely to support life. What we do have is a model showing that for worlds orbiting a star of above 0.45 solar masses, the tidal effects do not overwhelm the possibilities for surface life while they do allow the formation of a protective magnetic field. Some of the magnetic fields generated last for the lifetime of the planets.

>used simulations of planets around stars ranging from 0.1 to 0.6 of a solar mass

proxima centauri is 0.123 apparently. Is it good or bad that it's in the low end of the spectrum?

>post evidence
>i-its hypothetically possible guise
You're grasping /x/tard

Science fiction my ass.

Also this is as close as we get to interstellar colonization, so I don't get the retards saying "4 light years is too much"

en.wikipedia.org/wiki/Flare_star#Proxima_Centauri

> the resulting flare activity generates a total X-ray emission similar to that produced by the Sun.

I think we can handle flares that are as powerful as the ones from the sun. This is of course assuming the planet has an atmosphere and a magnetosphere.

All I'm saying is, don't discard it because of the Sun-level-intensity flares. Now, tidal locking is a real deal breaker.

not really meaningful tho because life on that planet would presumably evolve to live in red dwarf luminosity conditions...

Humans will go there in a few years. Mark my words.

we are the ayyy lmao's

what if america transport niggers and jews there?
than this earth will truly be heaven

Is this your article, OP?

I can't even find the author of the "news" article, so I can berate them.

DESU a planet in the habitat zone of a smaller star would be relatively closer and therefore experience stronger tidal forces.

This planet would be perhaps the best example of the effect, I'm not sure what would happen when it eventually becomes tidally locked, though.

(Note that if it by some chance had a substantial orbiter like the moon of earth it would be an extremely good candidate) (But we are far away from being able to see the moons of planets)

It could be pretty good, guys.

I'd say a 50/50 chance of life at some point with no large moon and almost certainly a 100% chance of life developing like Earth if this small planet has a similar orbiter.

The amount and persistence of tidal locking and tidal heating is extremely important. Earth would be similar to A planet like Mars and Venus at the same time right now if not for the moon.

>Earthlike planet around Proxima Centauri.

Isn't this half the plot to Proxima by Stephen Baxter?

With nuclear propulsion we can actually get there in about 128 years so a probe would be needed not a human.

Cant we just send there signals on all possible bands and expect a response in 8 years ?

If there's a civ more advanced than us, they already know we're here.

If there's a civ less advanced than us, they wouldn't capture our message

The chance that there is a civ at our level is basically null

we could still try. we also put a golden record on the voyager craft, no alium is ever going to read it but we still did it.

>they already know we're here.

Wrong.

Attenuation is a fucking bitch for communicating across that distance. You'd need a massive transmission space base many kilometers across using many megawatts of energy to blast out an ultra low frequency signal directed at that location to even have the slightest hope of anything reaching it that is remotely intelligible. Then they have to have an antennae array several kilometers in size to catch the signal and be pointed at us. And, vice versa if they are sending signals to us. Hell, we may be awash with millions-year old ultra low frequency communications, but we'll never know until we have an antennae array large enough to catch something with peaks that are 50-100 kilometers from each other.

Theyre not going to recieve our signals unless they focus their high power radio telescopes on us and listen. Even then they would have to catch the right channels to recieve any incoming signal.

When we discovered KIC tabbys star, we listened it for a while, and it took us over 6 months to analyze every frequency to see if theres anything at all.

If they are more advanced they would see our planet and signs of civilization through telescopes already

Original article was published by Spiegel, it is a respectable German newspaper.

There's a limit to that too and we have already come close to reaching it, sadly.

>respectable
>quotes anonymous sources

0 respect

How ? We have advanced telescopes too but we just discovered this planet even though it has been around for who knows how many centuries. Also we wouldnt hear anything from them even if they are sending us signals at this very second unless we direct our dishes to them, listen for quite a while and analyze all the frequencies which take forever.

I think you're a bit naive about the challenges of communication that takes light years and how we transmit these signals.

Most of me is like "shit, even if there was life it's probably long dead now" but then part of me is like

"oh shit, if they're still alive they might be barely hanging on! We gotta go out and rescue them!"

There is something up with the fact that they tried to listen for communications from rabbis star, it's too far away for even signals extremely strong of our type we are looking for, it's ridiculous to deduce anything from it, the signal search was so inadequate they shouldn't have even tried in the first place, because saying 'we heard nothing' is meaningless and misleading

>being this retarded

>rabbis star
xD

You have to be 18 to post here

it is literally the closest exoplanet. 8years is a fucking great ping in this context

Thats not true. German here, Spiegel might not be total gossip trash but it is far from serious journalism

>it is okay to literally make shit up and post it as fact

unless they claimed there were 1000+ people there, I dont really get this picture

If ayys were real, what souvenir would you bring to them?
Personally I will give them one of my dakis.

A football, I chiseled it myself

Snail shell.
A cassette mixtape.

STOP

It is staged, that's all. It was filmed before the protest was planned. They stated there was 10s of thousands of protesters. When the protest actually happened there was about 7k.

It doesn't? How come? Please explain, i'm interested.

NIGGER WE DONT EVEN HAVE FLYING CARS OR JETPACKS YET. no way I'm going to rewrite that with caps off.

Cool mr reddit, but consider that those telescopes are already in the working

>There's a limit to that too and we have already come close to reaching it, sadly.
Bullshit.
First of all you have gravitational lensing and then you have hypertelescope swarms.

We have the technology. We will build it.

* a 100-pixel image of a planet twice the width of Earth some 16.3 light years away would require the elements making up a space telescope array to be more than 43 miles apart. Such pictures of exoplanets could make out details such as rings, clouds, oceans, continents, and perhaps even hints of forests or savannahs. Long-term monitoring could reveal seasonal shifts, volcanic events, and changes in cloud cover.

EXO-EARTH IMAGER (EEI)

* visible “portraits” of exoplanets can be obtained in 30 minutes of exposure, using a 150 kilometer hypertelescope with 150 mirrors of 3 meters.

* 10 km resolution at 4.37 Light years. That's about what our satellite photos took back in the 1960's. Certainly high enough resolving power to image landforms, islands, forests, whatever else is going on. This would require a hypertelescope array that is 1,500 miles across.

1 kilometer resolution would be a hypertelescope array about 10,000 miles across. That would mean a 100 million pixel image of an exoplanet.

* To resolve 30 foot objects looking 4.37 light years away the elements making up a telescope array would have to cover a distance roughly 400,000 miles wide, or almost the Sun's radius. The area required to collect even one photon a year in light reflected off such a planet is some 60 miles wide. To determine motion of 2 feet per minute — and that the motion you’re seeing is not due to errors in observation — the area required to collect the needed photons would need to be some 1.8 million miles wide.

Mission - To image 1-meter-sized features including life, on planets up to 550 lightyears away. This volume of space contains an estimated 89,000 G-type stars like ours, and 1.8 million stars of all types. It would take many decades of operation to survey all of them.

Angular Resolution - To see 1-meter sized features at 550 lightyears requires a pair of telescopes positioned 415-AU apart (415-times the Earth-Sun distance). They can be launched in opposite directions to positions 208-AU from Earth.
Assembly - About 3000 of the small mirror segments can be fitted into a larger triangular sheet with an edge length of about 57 meters. These large sheets can be stacked 54 meters high for transport. The 715 layers that comprise this stack can be unstacked again when the spacecraft reaches the 208-AU destination point, and re-assembled into an expansive array of mirrors, connected edge-to-edge, forming a parabolic reflector 1119-meters in diameter.

That's not how optical astronomical interferometers work. Once you get so large, you start getting shitty problems with the angular resolving power. That starts somewhere around 110-150 meters.
