How NASA Could Find Evidence of Life on Another Planet Within 25 Years (washingtonpost.com) 131

Posted by EditorDavid from the truth-is-out-there dept.
"In all likelihood, in the next 25 years, we'll find evidence of life on another planet..." begins a new essay by author Dave Eggers in the Washington Post.

"In more than a dozen conversations with some of the best minds in astrophysics, I did not meet anyone who was doubtful about finding evidence of life elsewhere — most likely on an exoplanet beyond our solar system. It was not a matter of if. It was a matter of when." [A]ll evidence points to us getting closer, every year, to identifying moons in our solar system, or exoplanets beyond it, that can sustain life. And if we don't find conditions for life on the moons near us, we'll find it on exoplanets — that is, planets outside our solar system. Within the next few decades, we'll likely find an exoplanet that has an atmosphere, that has water, that has carbon and methane and oxygen. Or some combination of those things.

And thus, the conditions for life. In a few years, NASA will launch the Nancy Grace Roman Space Telescope, which will have a panoramic field of vision a hundred times greater than the Hubble Space Telescope. And on the Nancy Grace Roman Space Telescope — we'll call it Roman from here on out — there will be a coronagraph, a device designed to perform something called, beautifully, starlight suppression. Starlight suppression is the blocking of the rays of a faraway star so that we can see behind it and around it. Once we can master starlight suppression, with Roman and NASA's next astrophysics flagship, the Habitable Worlds Observatory, we'll find the planets where life might exist.

To recap: For thousands of years, humans have wondered whether life is possible elsewhere in the universe, and now we're within striking distance of being able to say not only yes, but here.

And yet this is not front-page news. I didn't really know how close we were to this milestone until I visited the Jet Propulsion Laboratory in Pasadena, Calif., on a hot and dry day in June...
Eggers' article is part of an ongoing series called "Who is government?" (For the series Michael Lewis also profiled the uncelebrated number-crunchers at the U.S. Department of Labor, while Casey Cep wrote about the use of DNA to identify the remains of World War II soldiers for America's Veteran Affairs' department's.) But this week Eggers wrote that the work being done at NASA's Jet Propulsion Laboratory "is the most inspiring research and exploration being done by any humans on our planet..."

"No billionaires will fund work like this because there's no money in it. This is government-funded research to determine how the universe was created and whether we are alone in it. If NASA and JPL were not doing it, it would not be done."

Eggers emphasizes later that "doesn't mean it's intelligent life, or even semi-intelligent life. It could be bacteria, or some kind of interstellar sea cucumber. But whatever form it takes, we are close to finding it..."

    I think the most inspiring research is the one done right here on this one and only home we (still) have.
    It's nice to learn about the origins and what's out there and all, but if we don't understand what's going on right now with what we have and what we're doing to it, it's less important.

    Then again, it's less glamorous and imaginative, and it forces us to face our responsibilities and consequences.

I can't even begin to theorize about how our continuing efforts will affect our understanding and stewardship of this island Earth we live on.

Just look at countries like Iran or Afghanistan and you'll see evidence of that corruption.

        • evolution disproved the creation story in the bible ... which means jesus NEVER existed

          There's nothing in evolution that disproves the existence of a historic Jesus - of some of the stories told about him perhaps - but revolutionary leaders with messianic pretensions are a pretty common occurrence (Got one running for the American presidency right now). Maybe leave it to the historians and archaeologists to argue that one out.

Let me know when that "Howdy!" is coming because so far it never happened, certainly I've never heard it.

        • >Hallucinations that happen while the brain is shutting down during the process of dying is not evidence.

          Actually, we've flipped that one. It's now evidence AGAINST God, since we've learned how to trigger it at will with a magnetic pulse to the brain and are in the beginning stages of understanding how it works.

          For my money, the sooner our entire species evolves past this brain-flaw that produces this 'faith' and 'belief' nonsense, the better off we'll be in every aspect of life, but sadly at the rate we're going none of us alive today will l

    The speed of light is a bitch. In practical terms, it means nobody on Earth will ever visit a world that orbits a star other than ours. We may find microbes living under the surface of a moon of Saturn or something, but as far as complex life goes, Earth is it for life around the Sun.

    We have learned how to do remote sensing, though, and it's pretty awesome. Spectrographical analysis of starlight that has passed through an exoplanet's atmosphere can tell us a lot about the atmospheric chemistry going on there, even from thousands of lightyears away. While there is uncertainty involved because we can't always tell what is produced by an Earthlike biosphere vs. a previously unknown geological process, if we see something the size of Earth orbiting a star at a distance that allows liquid water on the surface, and detect certain compounds in its atmosphere... damn right we're going to know we've found life.

    Not only are we starting to look for these kinds of things, we're rapidly getting better at it in terms of precision, accuracy, understanding, and rate. There are around 30 billion stars in the Milky Way that could potential have a truly Earthlike planet orbiting them (not Earthlike as astronomers use the term, but as in theoretically the same in all the characteristics that caused us to be here talking about it).

    If you start with the assumption that we're not special, and the understanding that we're just the outcome of chemistry based on the available type and quantity of material that collapsed and formed the Solar system, then it's just a matter of how good or bad the odds of an Earth forming are... and there literally 10s of billions of chances floating around our galaxy. We don't have to go to them, their light comes to us, we just have to look.

    So yes, unless the odds of life evolving around a star in a galaxy are in the trillions-to-one-against range, we're going to find it. And given how quickly the technology is advancing, most of us will live long enough to see the announcement of it.

    • Maybe we will. Finding life does not require finding other civilizations, which is the assumption that people jump to. There has been life on earth for nearly a billion years and detectable civilization for less than 200. Based on current trends, it does not seem likely that advanced civilizations are likely to last very long either. If there is another civilization out there that contact us, they are probably so advanced that they would want nothing to do with us.

If it takes 4.5 billion years (approximately) for one to emerge, on an Earth-like planet around a Sun-like star that life probably has a half-million year window even if it doesn't go extinct for any of a billion different reasons.

If a person were to launch from Earth and achieve relativistic speeds close to the speed of light, the journey to another star may take only a few hours from that person's perspective... so in theory, many people from Earth could visit a world orbiting another star. They just wouldn't be able to come back to Earth and tell you about it.

  • Is a large hint that this is BS, With such far off time scales they are hoping in less than 25 yeas no one will recall this.
  • there may be plenty of life in the universe trouble is we have to be in the same space \ time as it to find it.

  • Its likely that before the end of 2049 there will be life on another planet, but it won't be alien.

  • we could find intelligent life somewhere...

  • The UAP issue is gaining traction now, and unfortunately it's been repressed for about 70 years. Headlines are: They are here, we know, it's a secret, it's not good overall, what we know isn't right and we're very far down a food chain to them. There are large things in the sea, and things on the moon. In other news, James Webb has seen something(s) and the information is being discussed in closed congress sessions. It will be 2027 before amateur astronomy is able to see this apparently. Something is comin
  • First of all: the infamous '25 years' line. Just like 'we'll have practical fusion reactors' in a similar timeline. *eye roll*. I certainly would like us to find incontrovertible proof of life of any kind, even bacteria, on some celestial body other than Earth, but that '25 years' goalpost tends to get moved frequently, doesn't it?

    Next: 'for thousands of years' we've been questioning whether there's life elsewhere in our Universe? Well, no, I'd say it's significantly less than 1000 years, as beyond a cer
  • For starters, "scientists" have found the preconditions for life whereever they look for it. Titan. Venus. Exoplanets. Water. Phosphorus. etc. There's no doubt all the preconditions for "life" are EVERYWHERE. Most astrophysicists will tell you that is a fact. What they won't do is go the next step and say it's a logical conclusion that therefore there IS life on these places. It's just bad for your career to be the pioneer.. what's the saying? pioneers are the ones with arrows in their backs...?

  • I'm just wondering who would represent Earth if we did make first contact, terrifying thought!

  • In 2015, NASA’s chief scientist Ellen Stofan predicted that humans would find strong evidence of alien life within 10-20 years. She highlighted advancements in the search for habitable planets and microbial life on Mars.

    A 2017 NASA study on the Europa Clipper mission suggested that life might exist in the subsurface oceans of Europa, one of Jupiter’s moons, leading to predictions of possible life detection within decades.

    In 2021, NASA's new James Webb Space Telescope raised predictions of findin

  • I am not sure that it is inevitable that intelligent life will develop a civilization where resources are used to explore the universe to feed the intellectual curiosity of a few members of its ruling elite while other people lack both food and shelter.
  • I do not think it is a question, the odds make it a certainty for it to POSSIBLY exist elsewhere, but that does not mean that it does, only that by our extremely limited understanding of life, we see it as possible.

  • I predict the world will run on fusion energy before any life is found anywhere other than earth, unless it originated on earth and we brought it somehow.

  • Evidence is not proof. For example, methane is evidence of life. But you can have methane without life. Evidence is not even overwhelming evidence. Besides what is "life"? A little hard to define. If you demand say DNA, then maybe too restrictive. If you demand only replication, then maybe too liberal.
