giants

History, strange to refer planetary science as history, but the highest resolution photos of Neptune were taken by the Voyager twins back in the 70's. The two space craft Voyager 1 and 2 are now nearing the edge of the solar system. Talk about enlightening... things behave quite different beyond the touch of  Sol. At the edge of the solar system, solar wind is all but nonexistant, heat from our sun is negligible, the only thing that remains constant would be space... empty and cold. Do a google on Voyager, I'm sure you will be filled in on the heliodrome, or what ever the band in space at the edge of the  solar system is called, which we would know nothing of if not for Voyager 1 and 2. Star Trek did an episode featuring Voyager, as the alien vessel would keep making mention to "veeger" Spock figured that one out, go figure huh?
       One thing just occurred to me, seems all the Gas/Ice Giants have turbulent "big spots" weather systems on them, Jupiter has its big red spot, Saturn has a great Yellow and here on Neptune you see the great blue spot. Just an observance.
      Also noticed, Mercury, Venus, Earth, and Mars, the "solid" planets are inside the asteroid belt, once past that, the only solid forms are moons, all "planets" would be gas/ice giants. Something to do with solar wind, and/or heat... too obvious to over look.
