    One of the questions about Panspermia but it's even better to NOT be Panspermia. It's really important to be uniquely a Venus based life, to show that life can spontaneously develop in other solar systems.


    And that's what they said it would have to be unlike anything on earth.

    That last question kinda threw them. They don't know what biological process produces phosphine on earth.

    Which one, light and dark side?

    Would only be able to look at the dark side of Venus efficiently from orbit of Venus.

    Microbes thrive on Earth in the absence of Oxygen or by Industrial means.

    Surprised this hasn't made news headlines.

    If there is life in our own solar system in addition to ours on another planet then what does that say about the probability of life in the rest of the universe - highly likely I'd say.


    There is absolutely no doubt whatsoever that this universe is teeming with life...

    No, the question before that asking if they knew what produces the gas on Earth. They couldn't definitively answer, but one (Sarah?) said that she was sure (without proof) the gas is produced biologically on Earth.

    There was a couple of questions they didn't provide speculation about. Unknown...

    Despite a large body of robust circumstantial evidence for the production of
    phosphine by life, the exact mechanisms for biologically-associated
    production of PH3 are still debated, and the metabolic pathway leading to PH3
    production in anaerobic bacteria is unknown. However, we note that the
    absence of a known enzymatic mechanism is not evidence for the absence of
    biological production. The synthetic pathways for most of life’s natural
    products are not known, and yet their origin is widely accepted to be biological
    {page break}
    because of the implausibility of their abiotic synthesis, their obligate
    association with life, and their chemical similarity to other biological products.
    For example, a recently published, manually curated, database of natural
    molecules produced by life on Earth contains ~220,000 unique molecules of
    biological origin, produced by thousands of species (Petkowski et al. 2019a)
    while the number of known, experimentally elucidated, metabolic pathways
    from organisms belonging to all three domains of life is only ~2,720 (Caspi et
    al. 2017). Further examples of the complexities in discovering metabolic
    pathways for molecules associated with biological activity are provided in
    Appendix E.

    Sky at Night was interesting, they were able to explain it better in a relaxed format. Repeated on Thursday at 7pm.

    The demonstrations of sulphuric acid done on the program with the sugar, peas and then succulent plant show promising hypothesis. Although a few drops of acid on a very hardy plant is hardly a controlled experiment. More so done to say if there is microbial life there it might have evolved to survive in the acidity of Venus's atmosphere.

    Overall.


    This is a massive discovery. It's either new chemistry (exciting to only scientific minded people, in the main) or actual alien life.


    If it's, amazingly, the second then it it will have ramifications for societies and religions around the world

    This is more a philosophical discussion, but I think it'd need to be intelligent life, especially if they still had their own creation myth religion.

    The philosophical ramifications might not be as challenged as you would think. Could just be confirmation bias for most of them!
