Plankton in the Clouds 84

An anonymous reader writes "NASA is reporting that the September 1997 Pacific hurricane, Nora, was able to deliver sea salt and plankton as far inland as Oklahoma. The tale-tell signs of prismatic light halos around cirrus clouds pointed to ice crystals with nucleated hexagons and sea-salted clouds. Various proposals have been made previously about such 'life in the clouds' proposals on other planets like Jupiter and Venus."

    Scientists were surprised to find what appeared to be frozen plankton in some cirrus crystals collected by research aircraft over Oklahoma, far from the Pacific Ocean.

    So they found some dead plankton. I'd be much more impressed about the connection with Venus if they were still alive while in the clouds some how.

    A few years ago, in Houston I saw a pale rainbow around the almost-full moon at night. It was a very cold night for Houston (below freezing), but since it was Houston, the humidity in the air was very high. Someone explained to me that the rainbow was because the humidity in the air was frozen into ice crystals which then had special refractory properties.

    Based on this article, I have to ask: Could saltwater have been a better explanation for this beautiful phenomenon? Does anybody here know?

    life as we know it is possible anywhere there is water. At this point, simple life forms like algea and bacteria on an extra-terrestrial world wouldn't excite me more than a "that's damn cool" type reaction. I'm to the point now that I'd expect there to be simple life on some of the other worlds in our solar system. I'd be a lot more surprised of all the planets and moons around us were completely dead. Now if they found concrete proof of extinct complex organisms on mars, or a sea full of life on Europa, It'd be a very exciting day. Jupiter's natural radiation could heat Europa's innards enough for life to thrive. Some say that the amount of radiation from jupiter would kill everything off; but life has a tendency to find a way to overcome obstacles. After all, despite all our efforts, spammers exist, trolls keep posting and the Saddams of the world keep on having their way.

      The big deal is that it would cause all the religious people to freak out, and they would have to rewrite their religion in a major way. I'm not naive enough to believe it would be the end of religion, they've adapted before in the face of overwhelming evidence that they were wrong.

        • That's OK. Some day you'll realize you aren't half as smart as you think you are, and don't have a tenth of the world figured out the way you think you do.

          Well, that of course assumes your ego gets out of the way, so maybe I'm exercising a little too much blind faith here as well.

          This is not flamebait. Religions don't have a very good track record when it comes to accepting new discoveries that contradict them.

        You're painting with an awfully big brush there. I don't know of many religions where "life only exists on earth" is a major doctrine.

        I'm sure there are some people for whom it is a strongly held belief, but for each one of those there are many more who do not have a strong belief either way, and even quite a few for whom the discovery of life on other planets would be a

    • Jupiter's natural radiation could heat Europa's innards enough for life to thrive.

      I do not think it has anything to do with radiation from Jupiter (since any radiation would simply be reflection from the Sun), but instead the heat is caused by the intense gravitational tidal forces from Jupiter (similar to the tidal effect of the moon on Earth). Gravity is constantly compressing and altering the shape of Europa and this friction causes it to heat up to the point where liquid water can exist (under the sur

    I guess the guys being too hopeful. Even if it is micro-biological life, it needs some time to form out of basic building blocks.

    Up in the clouds the conditions are too violent and volatile and material transfer is past, so life may land up there, but it is difficult for it to develop from there, unless the whole cloud is made of primodial soup, like the depths of jupiter where there is thich murky cloud where scientists think life is possible.

    But life forming in clouds like venus has, sorry i dont bite.

    If you find this concept interesting, and enjoy Sci-Fi, try the book Wheelers [amazon.com] by Ian Stewart and Jack Cohen. It's a neat book that fleshes out this concept in intricate detail. I picked it up in a clearance sale at my local book store, and was glad of the purchase!

    by Freeman Dyson talks about this in his wonderful book published in 1999. Specifically he talks about the chances of finding lifeforms on Mars and Europa (a satellite of Jupiter). He suggests looking into the space around Europa instead of on the surface for "freeze dried fish".

    From the final chapter: "Every time there is a major impact on Europa, a vast quantity of water will be splashed from the ocean into the space around Jupiter. The water will partly evaporate and partly condense into snow. Any creatures living in the water not too close to the impact (meteor impacts) will have a chance of being splashed intact into space with the water and quickly freeze dried."

    I'm not sure if this book has been reviewed in slashdot, but it deserves another shot since so much here is relevant especially after the last shuttle disaster. Dyson is dead on track here.

  • IAJAP, I am just a programmer, but

    If this living material is present at that level, do we think it can precipitate out ? and if so, what impact do you think this would have on projects that analyse the minute traces of life in remote areas [sciencenews.org] ? Actually, what impact might that have on umbrella sales ??? ;)

  • plankton that was picked up by a hurricane out of the water, died and didn't originate there is a hell of alot different than life that developes in the clouds. I would thinkl that someone who knows how to type and use a computer would be smart enough to realize this but hey, maybe I've overestimated the inteligence required to do those kinds of things.
