Time lapse footage
When possible,it is always much better to put observations in proper
context with time lapse footage and the following spectacular footage of Uranus qualifies as something unique - http://hubblesite.org/newscenter/arc...99/11/video/b/ It is possible to see how axial rotation and rotational orientation (axial tilt) is seperate from the motion of the rings with respect to the central Sun.In short,the polar axis of Uranus does not tilt through 360 degrees as it orbits the same central Sun that we orbit,what is occuring is that a location will orbitally swing through 360 degrees like a crank turning around a central shaft - http://www.youtube.com/watch?v=YV9WkQkUHZ4 http://physics.uoregon.edu/~jimbrau/...13/FG13_06.jpg The Earth has an orbital component that turns through 360 degrees to the central Sun just as a location on Uranus does,while that component is seen in terms of variable axial inclination,it is hoped that there are just enough genuine astronomers who can intepret the time lapse footage of Uranus correctly and identify the same component for the Earth which generates seasonal variations in daylight/darkness and the variations in the natural noon cycles. It is not every day a person gets a chance to celebrate a new way to look at the Earth's motions and its effects but that is a personal choice allied with a bit of astronomical talent.It is also enjoyable and a worthy way to celebrate the power of modern imaging.Perhaps when people get tired of the unobservable junk dumped into the celestial arena and start to look at what can be experienced (the seasons/ astronomical motions) then this great discipline will returnb to its former glory. |
