NASA http://www.msss.com/mars_images/moc/...mericas250.jpg With satellites out there capable of tracking the orbital surface rotation via the Northern and South polar latitudes as they turn through a constantly vertical circle of illumination, this is the charter of NASA rather than the mismanagement of information in the 21st century.

"Explanation: Today, the Sun crosses the celestial equator heading south at 0951 UT. Known as the equinox, the astronomical event marks the first day of autumn in the northern hemisphere and spring in the south. Equinox means equal night and with the Sun on the celestial equator, Earth dwellers will experience nearly 12 hours of daylight and 12 hours of darkness" NASA
http://apod.nasa.gov/apod/ap070923.html The fact is that there is daylight for 24 hours at both the North and South polar latitudes at the Equinox as a means to draw attention to the Earth's dual daylight/darkness cycles - http://www.esrl.noaa.gov/gmd/obop/spo/livecamera.html The worst creatures in this forum will continue doing what they are doing and exist in ignominy however this is an opportunity for decent people to highlight what this era can achieve by taking the time to consider what is going on at the North and South polar latitude presently where there are 24 hours of daylight. |

Some dummies may assume this is an attack against NASA as opposed to promoting an innovation so while the comments do contain an implicit statement that the standards fall well below what it is required to practice the astronomy of cause and effect, at the same time I use the very instruments NASA send into space such as imaging from the HST.
While the hideous tilting circle of illumination may satisfy those who believe the Sun moves North and South of the Earth's Equator with the Equinox as the crossover point and described in the APOD website, the actual dynamics behind the Equinox go unattended. The vertical terminator defines the Earth's orbital motion through space and handily enough there is only one image that carries that information - http://www.msss.com/mars_images/moc/...mericas250.jpg With the central Sun implied, it is easy enough to envisage the entire Earth turning using the polar points as a reference thereby explaining the Equinox event in terms of a surface rotation as a function of the orbital motion of the Earth. I am not appealing to or contending with any particular organization or person, the information is available and as long as it makes sense to a person then that is all that counts at the moment. If there are people paid to call themselves astronomers while promoting a tilting circle of illumination then they are receiving money under false pretenses, the fact that there is a created public charter for NASA yet they fail to carry out the obligations then this is a really different matter and much more serious. So, with daylight featuring at both the North and South polar latitudes presently it draws attention to the dual surface rotations of the Earth to the central Sun rather than a tilting Earth or an awful tilting terminator. |

I am starting to see this 'tilting terminator' more and more often with each passing year despite the introduction of dual surface rotations correlating to the planet's dual daylight/darkness cycles providing the only explanation for the Equinox event -
http://www.theweathernetwork.com/us/...equinox/57522/ Is there nobody with a calm intelligence to realize that there is always roughly a symmetry between daylight and darkness at the Equator throughout an orbital cycle ?. A simple comparison in size between the Earth and the Sun immediately obliterates this notion of the Sun crossing the Equator at the September and March Equinoxes - http://forums.pelicanparts.com/uploa...1202505560.jpg The fundamentalism which gives rise to a 'tilting terminator' is rotting Western astronomy from the inside. |

So the sun aways seems to be above the equator and rising and setting times always the same? I think not!

When Copernicus first proposed the reasons why the Earth turned daily and moved through space to account for the appearance of the Sun and the wandering nature of the planets, the major distinction was the observed direct motion of the Sun through the background field of stars with the wandering nature of the planets.
The viewpoint of Copernicus and his contemporaries could only satisfy the observed retrogrades of the outer planets but not the inner planets as the perspectives seen from a moving Earth are different. Genuine astronomers need to develop the ability to filter out the daily rotational inputs and look at the planets, the Sun and the background stars from the orbital motion of the Earth only to make sense of the insight of Galileo that the phases of Venus represent an additional affirmation that the planet circles the Sun - https://upload.wikimedia.org/wikiped...Venus2.svg.png While being okay, what that image and all other images like it don't convey is what input the Earth's own orbital motion factors in. This is why a stationary central Sun and a moving Earth is far more relevant than the relative speeds which account for the retrogrades of the outer planets. That wonderful graphic were the stationary Sun is out of sight and the inner planets move against and eventually with the background field of stars (retrogrades) is the only possible way to treat the observations like men,women and astronomers. https://www.youtube.com/watch?v=MdFrE7hWj0A A 'wandering Sun' is the work of thugs or the demented. |
