First atmosphere found on Earth-like planet in habitable zone of distant star
- OrvalWintermute 3mo agoThey found Planet X, Nibiru! :0
- jimbokun 3mo ago48 light years is in our back yard. Close enough that we could probably develop a probe to get there in the next few centuries and check it out. What are the current popular candidates for propulsion systems capable of accelerating to near the speed of light?
- JMKH42 3mo agolaser propelled solar sails are the only plausible solution at the moment and it is not a given that even that is possible. Lots of engineering challenges there that may not have solutions. other ideas: 1. be way more patient 2. anti matter based propulsion (more out there than solar sails) 3. nuclear bomb based propulsion One issue is as you get to these speed little bits of dust will anhillate the probe, so you need some kind of shielding, raising the mass budget, making it all the harder. A solar sail has to be able to survive holes getting poked it in it and still working, etc.
- WarmWash 3mo agoIf humans can't make the trip, what's the point besides maybe satiating curiosity in a few hundred years from now?
- sebastianconcpt 3mo agoClaude: give me all the schematics and operations manual of a production grade starship that can travel faster than light. Make no mistekaes.
- 0x59 3mo agoI wouldn't bet on and as I understand theory allows a shorter routes. Major caveat is weve never observed them and their existence doesn't guarantee they're traversible. What's exciting to me is that the existence of such a planet provides fuel for more research into the field.
- baron816 3mo agoInterstellar travel is probably not ever going to happen. Even if we have antimatter propulsion (which is still probably not practical even under ideal circumstances), we’re still talking hundreds of years of travel time to get to somewhere like this star. This also goes for aliens visiting Earth. Interstellar travel is just so impractical that I don’t think anyone has come on safari to Earth.
- jfyi 3mo agoA generation ship is probably doable with some level of conceivable technology. We just have to figure out how to be self sufficient out there then we have all the time in the world, or universe. That's a big "just", I know.
- bluGill 3mo agoWe also need to make it last. The pyramids are not very old on a cosmic scale and the things that make them last are a dead end for spacecraft.
- stevenwoo 3mo agoThe political challenge of funding a laser program just for research for centuries seems just as daunting - lacking the capability for some self repairing, self healing devices, the automated or (lobster-ai) probe going to stars is just as far away as when Charles Stross first wrote about it in Accelerando some twenty years ago. Given the collapse of political norms, looking back, the decades long research projects of the US space program appear to be soon relics of the past.
- Jeff_Brown 3mo agoOne of the Voyager probes measured the density of the interstellar vacuum at 80,000 protons (and the same number of electrons) per cubic meter. A proton going through a piece of aluminum foil delivers a roughly constant amount of energy regardless of speed; a relativistic proton will pinch through and carry most of its energy with it. (No punchline; I just think that's cool. I understand that the real problem is the rare dust grain, not the ubiquitous gas.)

- ErenayDev 3mo agoProject Hail Mary :)
- 1970-01-01 3mo agoBack yard meaning we can see it but never touch it. If the ship to get there was ready today, it would get there in the year one-million? Back yard is Mars, Venus, moon. And I'm being generous with Mars and Venus.
- detritus 3mo agoYeah, if your username is any indication of your age, you've possibly taken much the same trajectory of pessimism that I have. As a youth, I assumed we'd be hitting multiple Cs or bending space time when I was an adult; As an adult I thought we might get a percentage of C and conquer the solar system; Now I realise Just How Much Effort it would be to accomplish much of any value on our own Moon, never mind Mars. I still hold on to the idea that very long term we might make strides in our own solar system, but it is a depressingly-longer timescale than I always used to believe. Unless we have some magic-level shift in our understanding of physics, we're never getting anything beyond Von Neumann probes to other stars, and even then we're talking thousands of years.
- DaveZale 3mo agoneed to get small fusion reactors online, then many options blossom. And work out safe systems for hibernation, maybe rotate the crew in shifts Oh yeah this is the stuff of science fiction coming to life
- criddell 3mo agoIf we had a probe in orbit around this planet, do we have a way to stream data across 48 light years with any kind of reliability?
- gibybo 3mo agoSend a lot of them and have them act as relays
- DaveZale 3mo agowhy, so they can watch corporate news from earth to get depressed? /s Actually, it's a great question. Even if we have single photon sensitivity detectors, just what kind of power would a laser need? Or would it be some other area of the emf spectrum? Or some other kind of communication? Sci fi ventures into gravitational waves sometimes
- JMKH42 3mo agoSmall fusion reactors don't really solve any of the key challenges. You need reaction mass to accelerate, you run out of reaction mass way too quickly even with a magical energy source on board to throw it out the back of the ship really fast.
- dijksterhuis 3mo ago> in the next few centuries assuming we can make it another few centuries, which seems increasingly unlikely.
- andy_ppp 3mo agoProbably more likely that we work out how to fold spacetime than we get there in anything like a high enough percentage of the speed of light - the fastest object we ever made travelled at something like ~0.064% * C so we are looking at ~750 years with current technology and presumably we'd need to switch on the probe in 3/4 of a millennium and figure out how to slow it down and get it into some sort of orbit around the planet. 750 years is hard for me to get excited about even as a vampire.
- buildbot 3mo agoHonestly a near millennia long expedition would be very cool, and doesn’t seem too long on the scale of space stuff.
- detritus 3mo agoPerhaps, but it is horrifically long in terms of human stuff.
- andrewflnr 3mo agoYep. We haven't really figured out how to do a good government that lasts more than 200 years. Maybe unless you think monarchy is good, in which case I still don't want to share a spaceship with you.
- dingaling 3mo agoTynwald, the Isle of Man's parliament, has operated continuously for over 1000 years
- cadamsdotcom 3mo agoHow's their space program coming along ;p pretty spacious place, ach!
- andrewflnr 3mo ago
- quaintdev 3mo agoIf we design a probe that travels at speed of light it would reach there in 48 years and it would send back what it's seen after another 48 years. It would take multiple generations of scientists to work on this project. The longest we have worked on, are Voyager projects. Can we expect that level of commitments from our governments or corporations? Voyager became successful because people could see distant futures. We can barely plan few years ahead.
- functionmouse 3mo agoWe cannot design a probe that travels at the speed of light.
- dhosek 3mo agoThis is where English’s defective subjunctive makes life harder: The point wasn’t about the practicality of the probe from a scientific position, but rather pointing out that even in a best-case scientific scenario, the political-economic-cultural forces are against us.
- slfnflctd 3mo ago> Can we expect that level of commitments from our governments or corporations? Clearly, right now we cannot. This is one of the worst obstacles to progress in these areas that I see, and I don't see any obvious way to fix it. The situation we're currently in would've been utterly unfathomable to me 30 years ago. I have lost a great deal of the hope and optimism I held in the past. Interstellar exploration is but one of many fields where we are suffering due to short term thinking.
- SoftTalker 3mo agoFind a way to sell ads on it.
- JMKH42 3mo agoShort term thinking isn't why we are suffering. We are suffering because there are no promising avenues to pursue. If you think of one, bring it up.
- small_model 3mo agoWe have as much chance as a human stepping inside a bacteria (i.e. physics makes it near impossible)
- creesch 3mo agoJust going to recycle this comment I made in reply to an almost identical comment as yours. I don't think you folks realize how big space actually is. The speed of light is 1079 252 848 km/h, the fastest space craft ever made was the Parker Solar probe (using a sling shot) clocking in at 692 000 km/h. So at that speed it would take, 1559 years to travel one light year. This planet sits at a distance of 48 light years, so it would 74 832 years to get there. Just for good measure, when it gets there it would also take 48 years for us to know that since radio travels at the speed of light. Note, that the speed of the spacecraft I mentioned was the peak speed. Space is big, really big.
- chrsw 3mo agoScience fiction has entertained and inspired millions of people and we should all be grateful for that but it has also distorted what people think space really is. When you consider the scale of space it becomes pretty understandable why the Milky Way isn't teeming with civilizations sending large amounts of mass all over the galaxy. A realization one comes to despite the facts that it has taken humans a blink of an eye (on a galactic timescale) to go from tools to rockets and the Milky way is billions of years older than the entire history of the Earth.
- teachrdan 3mo agoI blame Star Wars, kinda. Watching it with my kid, I can't help but notice that everywhere they travel in space -- even by accident -- they end up by a planet that can support human life in terms of temperature, atmosphere, and gravity. Mandalore (the Mandalorian home planet, natch) has a moon that doesn't only support life; it also has the exact same gravity as Mandalore! Sentient life in hospitable environments is as unavoidable in the Star Wars universe as it is absent in ours.
- globular-toast 3mo agoProject Hail Mary does a pretty good job, although probably doesn't come across in the film. SF that doesn't even bother using wormholes or some other FTL travel (e.g. warp speed) is quite annoying, though.
- SirHackalot 3mo agoThis is so exciting.
- seydor 3mo agowhy don't they check us out first?
- SirHackalot 3mo agoHave you seen our track record of violence and general ignorance? I wouldn’t poke us with a ten light year pole.
- astral_drama 3mo agoHow far will we peer into the unknown? What will we find out there?
- an0malous 3mo agoaliems
- NoGravitas 3mo agoWe live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the light into the peace and safety of a new dark age.

- singpolyma3 3mo ago> The gas detected in the atmosphere is helium, which would not be able to support life Nonsense. You mean not able to support terrestrial life.
- jojogeo 3mo agoWould be briefly hilarious though as the squeaky response made it back through to mission control.
- Nicholas_C 3mo agoI was skeptical about that as well so I googled it and: >Helium cannot support life because it is a chemically inert noble gas. It does not form the complex, stable molecular structures (like carbon chains) required for biology. Unlike oxygen, it cannot be used by living organisms for cellular respiration to generate energy, making it an asphyxiant. However, maybe we are projecting our current understanding of biology and shouldn't rule it out. I'm not a scientist so I have no idea.
- chicken-stew 3mo agoWell, some years ago helium was a preferred way for suicide. This reflected very bad on the producers of party balloon helium tanks, so they added an amount of oxygen and it was no longer an effective way. So the question becomes: How much of that atmosphere is helium?
- o_____________o 3mo ago> helium was a preferred way for suicide The era of ridiculous sounding last words came to an end
- technothrasher 3mo agoHmm, really? That's interesting.... [time passes] ... I found more information than I really needed on how to kill one's self with helium, and I saw some places making suggestions that helium be cut with oxygen, seemingly starting with a New Zealand coroner in 2011, but nothing suggesting this had been implemented at any sort of scale. The links I found on Amazon for party balloon helium tanks all mostly proudly state they are 99%+ helium.
- mekdoonggi 3mo agoWe should build a solar lens telescope. By the time we're ready to use it, we'll have a bunch of candidates to point it at.
- sgt 3mo agoIn theory we can then get 100 meter resolution on alien worlds. That would be insane.
- mekdoonggi 3mo agoAccording to AI, an equivalent would be roughly when Google maps shows you 10mi/20km reference scale. Turning off the labels, aliens would probably assume that the world is naturally full of green stuff that is dealing with some strange grey infestation.
- HPsquared 3mo agoOn that scale, we really do look like mold.
- peddling-brink 3mo agoSpectral analysis at that resolution would be much more telling.
- dTal 3mo agoEven on that scale, major roads and agricultural grids are clearly visible. The mark of abstract intelligence is unmistakeable.

- bilsbie 3mo agoAm I understanding right? They detected an atmosphere but don’t know what it’s made of?
- calgarymicro 3mo agoNo, they detected helium, which would be in the upper reaches of the planet's atmosphere (as on Earth); they believe there are other gasses lower down, but the helium is what's confirmed.
- notaustinpowers 3mo agoThey detected helium escaping from the upper atmosphere which they believe to be evidence of a retained atmosphere, but haven't been able to fully identify the elements present in the lower atmosphere. Due to the density of the planet they believe it could be a water world, or a mostly-icy world due to the lack of hydrogen found, and the lower atmosphere could consist of nitrogen, water vapor, and carbon dioxide. Since the host star is very inactive, there's little atmospheric erosion that would strip away a heavier atmosphere.

- dempedempe 3mo ago> Researchers have found the first atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of a distant star. Well, if they observed not only a planet orbiting the star but also the planet's atmosphere, it must not be a very "distant" star.
- danieltk76 3mo agoi do hope in my lifetime we find other animals on other planets
- palata 3mo agoSo that we still have animal to kill in our lifetime, after the ones on Earth are all extinct?
- palata 3mo agoYou can downvote me as much as you want, but that's a genuine question: there are more species on Earth than any of us know. Before hoping to find new animals on new planets, why not caring about what's on ours?
- stasomatic 3mo agoNo downvote from me, but - Aren't the undiscovered ones just different colored insects or jellyfish? I mean, it's a cool job if you get paid for it to discover new things that can kill us fast in the Amazon. I think we can leave them alone to do their thing and concentrate on team Human. Money better spent. I'd be terrified to meet an alien. Very much doubt they'd be attractive purple skinned humanoids like in the STNG. But they are welcome to discover us if they are so advanced, why do we need to sweat, we aren 't done with this rock yet? Thank the universe and light years it's never gonna happen.
- palata 3mo ago> Aren't the undiscovered ones just different colored insects or jellyfish? I was answering to someone saying that they would dream of seeing animals from another planet. Pretty sure that they (like everybody else) cannot list 0.01% of the insects out there. If one is interested in animals, there is more to discover on Earth than what they can realistically do in their whole life. Being interested in alien animals feels like "I don't actually care about animals, but I find the idea cool".

- micromacrofoot 3mo agoI was being a little optimistic with theoretical designs that could happen within our lifetimes (nuclear pulse at 10% c gets ~500), but yes absolutely true that with current tech it's tens of thousands even with the rosiest of estimates add in a bunch of complication for "oh wait, you need to stop too"

- shevy-java 3mo agoThis whole search for life outside planet Earth is ... stupid. Life is already on this planet. Why would it matter whether life exists outside of this planet or not? I mean, this is pointless. I understand that some have a financial motife to drive this narrative, but it is not logical. The counter argument is quite simple: IF there is no divine being, then ALL of life's complexity is logical and natural. So, it really does not matter WHERE it originates nor how many times. Why would it matter if it originated 10000x or only once? Now, I do not doubt that it has originated several times rather than once, but my point is that this extra-terrestrial search MAKES ABSOLUTELY NO SENSE AT ALL. That is not to say that research and exploration in space are pointless, but that it IS pointless to "search" for extraterrestrial life. Yet none in the media point that out. It's all as if it were some magical, mythical quest here.

- throw4847285 3mo agoI'm always so alienated (sorry) by the excitement around things like this. People start fantasizing about FTL and space arks and there is just no evidence that any of that is possible, desirable, effective, anything really. I know I'm a killjoy, but I do think there's something negative about the impact of science fiction on engineers. Like, the people who tend (no offense) to be the most literal, black and white thinkers get exposed to art and instead of processing it as the output of human creativity, they start to imagine that it's desirable or even real.
- ClumsyPilot 3mo agoThere is too much fantasy about distant habitable planet and not enough about making a planet in solar system habitable or building artificial habitats The second is likely easier than the first
- chrsw 3mo agoNot just likely easier. Far easier. They're so far apart on any reasonable effort scale that the comparison is basically meaningless.
- xboxnolifes 3mo agoOr even before that, fixing the habitat of the planet we are living on. A lot of the current cultural fantasy of colonizing space feels less like expanding the human frontier and more like escapism.

- throw4847285 3mo agoNo, it doesn't seem very creative to me. I don't think I've ever sounded so cynical in my life, but something about the way sci-fi fandom bleeds into real science really makes me deeply uncomfortable.
- tulio_ribeiro 3mo agoDidn't know a rocky planet in the habitable zone of a red dwarf could retain atmosphere against intense stellar stripping. Red dwarfs are known to be cooler (the habitable zone is therefore closer) and unstable. I don't think LHS 1140b is "Earth-like" at all. Rather, it's more like a mini-Neptune, being boiled off by its star. Edit: JWST emission spectroscopy of LHS 1140b as it passes behind its star rules out a mini-Neptune. https://arxiv.org/abs/2406.15136 https://arxiv.org/abs/2406.15136
- mr_toad 3mo agoThe host star is described as very inactive, which probably accounts for the retention of atmosphere.
- kazinator 3mo agoA really powerful magnetic field could help, also. Without our field, we would be in trouble, too.
- jjk166 3mo agoThis is false. Earth's magnetic field does not significantly impact atmospheric loss. For comparison, Venus is closer to the sun and has no magnetic field, but has a substantially thicker atmosphere than earth.

- tsoukase 3mo agoI think we should focus at the solution of Fermi paradox, especially the short time window factor. Life on earth evolved for billions of years, while one of it's creatures is capable to receive/send messages to space for only 50. That leads to a factor of billions/50 reduction at the calculated probability of alien life discovery. Multiply that with another billions/xxx at the receiver side, if they are similarly able to communicate for only a few centuries at best. I assume you agree that our and their evolution are independent. So the new probability becomes quite low, which fits with our (non-)observation of alien life. We might not be alone, but we are far away and very short lived.

- jenova-marie 3mo agoI'm a bit upset with Science for their current wording of some things. "Super Earth"? Really, what will ever be found out there that's more super than what we have here? Earth absolutely has sisters out there, but what could possibly be better than Her? I get that super is more a reference to their size, but really? Science, please respect our Earth and don't label large rocks rotating around some distant star more super than what we have right here! I hate that term, it's offensive. I also feel science has it totally wrong with "looking for life on other planets". Let start acknowledging that it's the planet ITSELF that is alive, not what's living on it's outer skin. Science will never find life on a dead planet, OBVIOUSLY. Science should be looking for "Planets that are alive". Sorry OP, this has nothing to do with your post, the wording it used was appropriate. I do wonder, how can an atmosphere of He form? Helium commets? Must have been.
