I read that article. The more I think about the ice and gas giants the more I think they're actually failed stars and not planets at all.

 

The organic molecules found in space amaze me. I understand how stars through fusion reactions create heavy elements and spew them out into space, but organic compounds are much different. Most organic reactions are endothermic so there has to be a source of energy to kick the reaction off, however if the temperature is too hot (> 800 C or so) the molecule will crack back to its constituents. Besides these gas giant planets are extremely cold except in their very outer atmosphere, so where would the energy comes from to drive chemical reactions to form organic molecules like ortho-carbonic acid. So if such compounds are formed on Uranus or Neptune, then there must be a sweet spot somewhere in the atmosphere where the temperature is warm enough for such reactions to occur and the reactants must of course also be present. Alternatively perhaps such compounds are formed in a warm gas cloud near a star and then the compounds drift in space and somehow find its way to these icy planets in the outer solar system. That such chemistry happens frequently enough in the universe to produce large enough quantities of these complex molecules that we can detect them spectroscopically is really mind boggling.

 

My understanding is the gas and ice giants are extremely hot deep inside probably caused by compaction pressure. Uranus may not be as internally hot but this seems to have been caused by what ever knocked it on its side?the other 3,Jupiter, Saturn and Neptune, generate more heat than they receive from the sun.Jupiter seems to made up of the same stuff as the sun.indeed it gives off such powerful radiation that it blackened the lenses of pioneer 10(or was it 11?)which flew past Jupiter in the 70s on it's way towards interstellar space.as an aside I feel sorry for pioneer 10 and 11 they hardly ever get mentioned when we discuss human made probes leaving the solar system it's always voyager 1and 2 which overtook pioneers 10 and 11.Jupiter doesn't seem to have the mass to be considered a brown dwalf star but the gas giants certainly seem to be part of the bridge twixt stars and planets?

 

Weird molecule shape. Of course, the swastika was originally a symbol of good luck and almost certainly a sun-wheel depiction. It can be dated back as far as the neolithic and has been discovered in many cultures. I think I had a bit of an X-Files moment there lol.

 

The swastika,or similar figures,can be seen in neolithic rock art often in barrows.these tombs are to be found in France, England, Ireland, Wales and Scotland. But there are many other symbols too, the possibly depict the moon,sun,planets and stars. Strangely far across the globe aboriginal rock art in Australia is very similar. I suspect however that they are images seen during trance like states and that the artists thought that the images where spirits.if you look at pictures of Finnish aircraft dating from the Finno Russian war you'll see the swastika on the plane sides reversed and on a white background plus the Finnish one is blue unlike the black German one.
