Stephen Hawking and Russian Billionaire Start $100 Million Search For Aliens

An anonymous reader writes: Stephen Hawking is joining forces with Russian billionaire Yuri Milner to start a $100 million effort to search the skies for signs of alien life. The initiative is called Breakthrough Listen, which will pay for large amounts of access to the Green Bank Telescope and the Parkes Telescope to scan the skies for signals over the next 10 years. They say the search will be 50 times more sensitive than previous attempts, cover 10 times more of the sky, and scan a greater portion of the radio spectrum 100x faster. They add, "All data will be open to the public. This will likely constitute the largest amount of scientific data ever made available to the public. The Breakthrough Listen team will use and develop the most powerful software for sifting and searching this flood of data. All software will be open source." The project is also supported by Frank Drake, Ann Druyan, and Lord Martin Rees.

      Remember that this is why "they won't find proof".

      1. The circumstances for life are pretty darned unique here on Earth. While there are *possible* duplicates in other solar systems, the chances of getting a planet that is habitable in another solar system is pretty slim. It's more than just being the right distance from the sun, but the planet size, the orbit of the moon, the molten Iron core, the amount of water, carbon, etc. I'm not saying it's impossible, only that there are going to be very few that fit all the narrow margins that allow known life to evolve and exist here. The odds of finding all this on one place are pretty small.

      2. The nature of "proof" would be a huge question. How would you. light years distant, observe something that proves life exists on a planet? Having water is not enough, being in the "zone" isn't either. Both would be a good start but how are we going to observe something that is undisputable proof of life? I have a few ideas, but all of these would be incredibly rare...

      2.1. One way would be to observe radio signals and find ones that are not naturally made. This would be incredibly difficult. There is a LOT of very noisy things out there in nature which make some very loud and unnatural looking signals. Even if the beings at the other end where trying to send us something, the chances of receiving enough information to determine FOR SURE the transmission came from other life and not from natural causes would be nearly impossible. They would have to point a very narrow beam of energy in exactly our direction and we'd have to be listening when it arrived with a very high gain antenna pointed in exactly the right direction with the ability to listen on the right frequencies at the right time. Where this *could* be proof, should it really happen, I don't see where this is even remotely possible. And given we don't have much understanding of how RF energy flows though deep space, even if we did hear something, it's very likely we wouldn't notice it in the noise. It would be like trying to hear a pin drop on a train platform as the express was running through.

      2.2. Another way we might get information about life on other planets is to observe the light spectrum reflected by or transmitted though the atmospheres of a planet of interest and look for things that only life would cause. This activity would be extremely hard and require very long observations of extremely distant objects as they orbit their suns. The only way I can imagine this working is to find a planet that is in the habitable zone and happens to have the right circumstances to allow life, but further, in order to observe it's spectrum, it will have to orbit on a plane that our solar system happens to be on, so we can observe the spectrum changes as the planet passes in front and behind it's star and calculate the differences. This will need to be done over a very long period of time because the portion of the spectrum we can observe from the planet will be TINY compared to the star and we will need to have many observations to get to a statistical assurance that we are not just seeing noise.

      So, in short, Not only is alien life (Like ours) obviously going to be pretty rare because the circumstances that lead to it are pretty rare, the chances that we can observe anything approaching proof is going to be even more difficult... The chances of stumbling onto proof, even if we knew where and when to look for it, would be nearly unimaginable, but given that we don't have much clue where to start the search, and the classical "needle in a haystack" saying doesn't even begin to convey the difficulty of the task, I find this "investment" interesting, but pointless for it's stated goal. They will not find proof of life outside of our solar system.

      But that's not to say there won't be good things that come of this... It just won't accomplish their stated goals..

Now, I do believe what Jesus said, whether it is politically correct or not. That He is the Way, the Truth, and the Life, and that no one comes to the Father but by Him (John 14:6). However, I do not see this as an exclusion of other religions, but, rather, an invitation to all, of any religion or multiple religions or no religion at all, to come to the Father, the only way that is possible, through Him. He doesn't exclude anyone. We exclude ourselves, by our choosing to live differently than the way He created us to. And yet there He is, reaching out and calling us anyway, all who will listen. I mean no offense to anyone by saying this, although I know from experience some will find it anyway. I hope that if in any way possible, through these words some might find hope.

And because it emits its internal sea straight up into space.

      That said, my dream mission is still a Titan sample collection/return mission using an RTG-powered rotary nacelle craft to fly in hops all across the planet over the course of a year, recharging its flight batteries overnight on the surface and taking small samples from every potential terrain - dune fields, rivers, the various seas, cryovolcanoes, etc. It would then re-dock with its ascent stage (single solid stage similar to a small Pegasus stage), lift the ascent stage out of the atmosphere (to reduce drag) and as fast as possible until it's drained its flight batteries (which would happen quickly with the added load), ditch all unneeded weight and fire the ascent stage to re-dock with the ion-powered orbiter that got it there. The orbiter, having spent the past year skimming the outer layers of Titan's atmosphere for return propellant that doubles as an atmospheric sample return, would then return to Earth, possibly skimming Enceladus's plumes and Saturn's atmosphere on the way for more sample returns.

      No question that would be a flagship mission, though, requiring two RTGs and three stages. An Enceladus-only return could probably be done on Discovery or New Frontiers budget (probably the latter).

      I agree with most of what you wrote. But I have the most interest in sample returns because we have such vastly greater analysis capabilities here on Earth than we could ever send on a mission - especially a lower budget mission. And by leaving off surface science hardware, you save development costs and a significant amount of spacecraft mass.

      Also, capturing samples, you don't have to land to have a low impact velocity. If you reach Saturn via ion propulsion then you could at little cost enter a Molniya-like orbit over the plumes so that the spacecraft would be nearly stationary relative to the particles during collection. Enceladus orbits are slow to begin with due to the low gravity (0,114m/s versus Earth's 9,81), and by positioning a high apogee or near-apogee over the plumes it might even be possible to collect jet material at lower impact velocity than one could from the ground. Enceladus's gravity would contribute to decelerating the particles and, if desired, one could have the probe's ascent phase over the plumes (rather than the apogee) for further relative velocity reduction. Impact velocity would be not much more than the random variation between the particles' individual trajectories, and some would impact with near-zero velocity. Combined with a carbon aerogel collector (much less dense than the silica aerogel used by Stardust), I seriously doubt you'd do any damage at all to what's collected - most particles shouldn't even melt.

      Every added system is added mass and development cost; landers don't usually come cheap, even on a low-gravity body like Enceladus. And dropping a lander near potentially unpredictable fissure geysers carries a risk. So I personally tend to favor spaceborne collection. That said, one would probably learn more from the surface, and you'd be able to sample surface ices as well, not just plumes.

    Further, we re-analyze the probability that two FRBs recently discovered 3 years apart within the same radio be am are unrelated. Contrary to other claims, we conclude with 99% confidence that the
    two events are from the same repeating source.

    1. Re:So Sure Are You? Howabout this source? by Anonymous Coward · · Score: 1

      Hmm, interesting. I'm not sure I entirely buy their statistics: they depend crucially on the assumed background rate of FRBs (so they can figure out how likely it is that they saw one by coincidence), and this rate is notoriously hard to pin down, since it depends on the efficiency of past surveys, which depend on all sorts of interesting technical factors. Still, the evidence is at least suggestive. The important part of the argument is whether the difference in dispersion measure between the two FRBs rules out a common source.

      So, the problem is this: FRBs show clear indications of dispersion, caused by the radio pulse travelling through a cloud of free electrons. The amount of dispersion tells you the column density of electrons, and it's more than the column density of electrons on a line through our galaxy. There are two decent explanations: (a) FRBs come from outside our galaxy, and the dispersion is caused when they travel through millions of light-years of extragalactic electrons, and (b) FRBs come from something inside our galaxy that has a cloud of electrons associated with it. Option (a) is more popular with astrophysicists at the moment, but the article you linked comes from some of the proponents of (b).

      If (a) is true, then a repeating FRB should always have the same dispersion, since extragalactic material, with a size of millions of light-years, can't change significantly in less than millions of years. If (b) is true, then a repeating FRB can have a different dispersion each time it repeats, since a smallish (but dense) cloud of electrons around an FRB source can change significantly (and so cause different dispersion) in a few years (or hours, depending how small it is). These authors' favoured model is that FRBs come from flaring stars: the flare generates a plume of electrons, then something on the star's surface produces a radio pulse that propagates up through the plume, getting dispersed as it goes. So their model, the issue of galactic versus extragalactic origin, and whether an apparently repeating FRB is really the same source or just a coincidence, are all very tightly linked issues.

      Other scientists have raised some objections to the possibility that FRB dispersion could occur in a flaring star, which are discussed in section 4 of your link. The most serious, I think, is that a dense plume of electrons from a flare would also be dense enough to absorb the radio pulse, so we wouldn't see it. I found this argument fairly convincing when I first saw it, but here the authors argue that if the plume is hot enough and sparse enough, then the optical depth (tau_ff; see equation 1) is low enough that the radio pulse can pass through the plume and emerge, dispersed, at the other end. I'm still a bit leary - I'd like to know just how dense the electrons in a flare are expected to be, and whether the semirelativistic nature of electrons at these temperatures affects the dispersion at all - but it looks at least plausible, and there's some corroborating evidence (which they point out) from the lack of FRBs detected at lower frequencies, which is expected in this model.

      What we really need is the detection of an FRB with an array telescope, rather than a single dish, to allow us to precisely localise it and cross-identify it with a star, a galaxy, or whatever produced it.

    Probably not. They're in the same place, yes, but they were deliberately looking at the location of FRB 110220 in case it flared again, so they were biased towards detecting a pulse from the same location. It's not quite as big a coincidence as the close locations imply. More importantly, the dispersion measure (DM) - a measure of the column density of electrons between us and the origin of the pulse - is completely different between these two FRBs, which indicates that they lie at very different distances. (Unless, that is, you follow the minority opinion that the free electron population causing the dispersion is local to the source, and compact enough that it can change significantly over a few years.)

    I also find it odd we havenâ(TM)t nabbed any new pulses since 2014, when we are searching more closely for them.
