In a little over a week, the South Pole will arrive at its maximum distance from the circle of illumination thereby will be at the center of the 33,312 mile Antarctic circle.
https://vimeo.com/172453097 No doubt they will trundle out the usual 'tilting' Earth next week while the beautiful and graceful rotations remain ignored even when other planets help explain why, in order to maintain constant orientation to the stars throughout an orbit, the Earth must turn once to the central Sun hence the June Solstice and Polar midnight at the South Pole and Polar noon at the North polar latitude. In any case, contemporary time lapse is genuinely beautiful and I am in love with the journey of my life with the journey of the planet. |

https://vimeo.com/172453097 The Polar points exist on the circle of illumination on the Equinoxes and midway to the circle of illumination on the Solstices.The surface rotation parallel to the orbital plane alters the daily arcs so even though the following graphic falsely attributes the direction from 'orbital' North-West to South-East in direction for the September Solstice, it is a small error due to unfamiliarity with the principles involved (even if I would notice) - http://afewbitsmore.com/img/2015_ecliptic.png The broken line through the center of the Earth is important for referencing the constant relationship of the North and South poles as they turn ,along with the entire surface of the Earth, parallel to that line as a function of the Earth's orbital motion. It should have dedicated graphics of course but it is always on offer for those who can work with the principles behind the seasons for our home planet and all other planets. |

* That would be the September Equinox where the direction of rotation is 'orbital' North West to South East using the East-West orbital plane as a reference -
https://en.wikipedia.org/wiki/Deep_S...-tilt-23.4.gif http://afewbitsmore.com/img/2015_ecliptic.png The circle of illumination provides another visible reference and especially using the rotation of the North and South poles along with the entire surface of the Earth parallel to that orbital plane. The most dramatic experience of this is certainly Polar sunrise and sunset where the Sun comes into view or turns out of sight for 6 months at a time at either poles. |

The phases of the Earth seen from Saturn compliment the perspectives which will always divide faster moving planets from slower moving ones depending on which planet in the solar system the images are taken from, only the furthest and closest planets from the Sun are denied one perspective or the other. I believe the astronomical community can do better by collating imaging into a simple narrative and finally put the remainders the the geocentric perspectives to rest or the troublesome celestial sphere perspectives. While many online forums do carry imaging like the one above, only in SAA have these imaging given or assigned relevance in a meaningful way. The fact that nobody comes here anymore is irrelevant. |

Do you know what else you could see from Saturn? That would be our own moon rotating on its axis, once for each revolution it makes around the Earth. |

Anyone, at least with common sense, could have made the observation that we extract the information that we along with the other planets travel around the Sun by assigning relevance to different aspects like phases for a faster moving planet or the temporary falling behind in view (direct/retrograde motion) that is easily discernible for the further out planets - https://apod.nasa.gov/apod/ap011220.html People must imagine that these observations must come with some sort of formal decorum when really they pop up out of the blue and the astronomer takes notice. Nobody pointed out before that observations from Mercury wouldn't show phases of any of the other planets while observations from Venus would show phases of Mercury but even when people seem hard to please nowadays, these things delight those who can appreciate them for their newness. |

You would also see the stars transition from left to right of the Sun as Saturn orbits our central star just as we see the transition from the Earth for stars close to the orbital plane. I am delighted that people do understand the new perspectives and I, as a Christian, am not put out by the lack of personal acknowledgement. Another Paul ,after which you are named, said what this total unselfishness means concisely - "What have you that you have not received from God? and if you have received it, why do you glory as if you had not received it?" |
