The sounds of Saturn

[GSOgymrat]

Sixty-two years after its debut it appears that the movie "Forbidden Planet" got the sounds right.

Spooky. I remember watching a documentary that explained the physics of Saturn and Jupiter, how though there is no solid surface, the immense gravity at its core is so heavy the molecules of its gases become so dense it's like a solid mass. Though nothing could get near its core due to this immense mass crushing anything the deeper it goes

That would be no shit spooky.

It seems that all the planets bey9nd Earth have some body of liquid water in or at their moons due to internal or tidal forces.  That increases the possibility of simple life everywhere unless our solar system is unique and I doubt that.

I'm almost completely certain that there is alien life somewhere out there in this vast universe. The question is, can we find it or is the hay stack too big for us to find the needle? And even if we could find a life-bearing planet, could we even observe or interact with it? Because of how long it takes for light to reach us, any life bearing planet we discover could already be desolate by the time we see it.

Two trillion galaxies, one hundred billion stars per galaxy. That's ... many ... system that might harbor life. If one in a billion had intelligent life we still would be too far away to hear from them before they passed into history. Many probably already have.

BTW, I told that to one of my cousins and he replied that he'd heard of billionaires, but not trillionaires, so I must be making that one up.

Not really, the Rothschilds, the Pope, and the Queen may be ... trillionaires.  They don't have to report to the IRS.

Everything we know about life just from our own one example here on Earth is that once it gets started, it gets into everything.  Think about some of the extreme environments that even within the last twenty five years or so, biologists would have all but ruled out as habitats -- and yet they host microorganisms.  Where we used to have a very specific list for life: You are not allowed to view links. Register or Login, liquid water, temperatures within a particular range, solar/tidal/geothermal energy sources.  Now it's beginning to look like a solvent (not necessarily water) and an energy source could be all it takes to build an environment.

So I'm bullish on (very simple) life within our own solar system.  I'm optimistic for the depths of Hellas Basin, where Martian atmospheric pressures just allow for the presence of liquid water.  I'm also optimistic about the remains of the Martian Oceanus Borealis (if it proves to have existed; there are tantalizing clues but nothing definitive), and Martian permafrost, and the Martian polar caps.  Got to go where the water is, at least on Mars.

But Mars is kind of low-hanging fruit, life-wise.  Enough material has transferred between the Earth and Mars over geologic time that it would not be surprising to find Martian life is DNA based either because it was contaminated by Earth life... or that Earth life started on Mars and found a more stable and suitable environment here.

So the really interesting places are Ganymede and Europa at Jupiter, and Enceladus at Saturn, because any life there would almost have had to independently start there.  While it's relatively easy to get impact ejecta from Earth to Mars, it's all but impossible to get it much further out, or get it from there to here.  I know I had an article on that, but I can't find it and I will keep up the search until I do.

Target Number One must be Enceladus.  It's effectively isolated from interplanetary contamination from Earth (and Mars), and thanks to Cassini's flythrough of the Enceladan geysers, we're confident there should be active You are not allowed to view links. Register or Login there (or something very like them), and we know those are viable habitats.  Europa is close enough to Jupiter that it is expected to have them too, as a result of tidal flexing, but Enceladus so far as I know is the only extraterrestrial place we have direct evidence to indicate them.

The slightest RNA type molecule in any spot on a body of water, and evolution is on its way.  And there are so MANY places that can have liquid water that the numbers are staggering.  And who says it needs water...?

Nobody is saying you can't have life unless liquid water is present, just that everywhere we've studied we've found that liquid water has life in it.

Covalent bonds are very useful.  Crystalline life forms like what Lohr assisted, are too rigid to count as life itself, more like a virus that uses other life forms.
