International Journal of Astrobiology’s Most Read Free to View

I’ve just received an email stating that the International Journal of Astrobiology is offering free access to its most read papers of 2009. So have a look and see – there’s some really interesting research going on there.  And this post is not in the least bit self-serving either!

  1. Hi Duncan, I also received that e-mail and read your paper with interest. I have a couple of questions. If I understand correctly, your parameters include life evolving (presumably also to possible intelligence) on planetary satellites. I understand that life may arise, but is it likely to evolve to intelligence under those circumstances? The other question is about the influence of our moon on the evolution of life on Earth – my understanding is that the Moon has been pivotal; may it not be equally pivotal elsewhere? Forgive me if I missed it in the paper (I am not an astronomer/cosmologist/astrobiologist or mathematician). Cheers, Ken.

  2. The question really is: is life “likely” to become intelligent in any circumstances? And the answer is maybe/maybe not. As we understand it currently, there isn’t a really strong reason for life to not thrive and become intelligent on planetary satellites. They may be quite peculiar from our point of view, but no less sentient.

    The Moon is really important for terrestrial life, as it provides orbital stability for the Earth, and produces tides (which some think to be important in the early stages of life on Earth, allowing the first animals to venture on land a chance to spend time in the sea without having to move too far). We did try and include moons in our latest work, which is coming out soon.
