• »Venustransit« (8. Juni 2004)
• »EUROPEAN ASSOCIATION FOR ASTRONOMY EDUCATION« (On June 8, 2004, Venus will pass in front of the Sun as seen from the Earth. This very rare event (no living person has ever seen one!) lasts about 6 hours and will be visible from most of Europe, Africa and Asia.)
• »History of Venustransits« ()
• »How many transits of Venus have been observed by humans?« (NASA.GOV) (December 4, 1639 // June 5, 1761 // June 3, 1769 // December 8, 1874 // December 6, 1882 // June 8, 2004 // June 6, 2012 // December 11, 2117 // December 8, 2125)
  the spacing between the transits is 122 years, 8 years, 105 years and 8 years. It turns out that this sequence repeats itself in this way, so that the next transit after 1882 occurs 122 years later in 2004, and the next one after that occurs in 2012 and so on.

  The two 8-year periods come from the fact that it takes 583.9 days for Venus and Earth to be closest together in their orbits, (called the synodic period) with Venus between Earth and Sun.(called Inferior Conjunction) It turns out that 5 times 583.9 equals 2,919.5 days and this is the time it takes for Venus and Earth to be exactly in the same orientation with the sun that they were previously. This also equals 8 earth years ( 8 x 365.24 = 2,921.9 days)

  The 122 and 105 year periods take into account the fact that the orbits are tilted by 3.8 degrees, so that the planet Venus is seen on the face of the sun.

  • Why the Creation Cycles do not end December 21, 2012, but October 28, 2011(By Carl Johan Calleman)
• »quetzalcoatl transits« (There are no historical records that suggest anyone was so lucky prior to 1639, although Montezuma may have spotted the 1520 (1520 war nix, sondern Juni 1518 und Juni 1510 - meiner Meinung nach) transit while studying the Sun for portends.
  The Mayan civilization had a particular fascination with Venus because it was associated with their chief god Quetzalcoatl and one of his incarnations, Kulkulkan.)

  8.Juni 04

  Straße der Pariser Kommune. Ich animiere Passanten durchs Reflektorteleskop von daisy@@t-online.de zu schauen. 'Mal durchschauen?' fragt er. Venus-Transit von 7.20- 13.22. Venus, Aphrodite, Quetzalcoatl, Liebe ("Ich habe die Liebe gesehen.")
  Himmels-Schauspiel für Sterngucker. Früher wurden Menschen geopfert. Sieht aus wie kleines, schwarzes Kügelchen eines Fahrradkugellagers. "Ihr macht die Menschen fröhlich." (Eine Holländerin aus einer Reisegruppe zu mir, nachdem sie durch das 700 mm Teleskop geschaut hatte.)
  "Cool."
  "Ganz toll wie im Fernsehen." ('wie in der Zeitung', ergänze ich)
  Alle bedanken sich. Einige müssen arbeiten. 9.45: Clouds.
