The Moon Crescent in the Tropics, Sky Watch




 
 
 
 
Posted by Picasa


All over the world people have seen the moon in various shapes as a full moon, as a crescent moon. The difference is that in Australia, and other countries in the tropical zone, the crescent is lying like a ship or like a dome over the country, while we in the more northerly or southerly regions see the crescent standing vertically. See the bottom most picture and compare it to the photos we took in Australia. We were amazed to see the horizontal crescent.

How was the moon formed? There are many theories.

The prevailing hypothesis today is that the Earth–Moon system was formed as a result of a giant impact. A Mars-sized body (labelled "Theia") is believed to have hit the proto-Earth, blasting sufficient material into orbit around the proto-Earth to form the Moon through accretion. As accretion is the process by which all planetary bodies are believed to have formed, giant impacts are thought to have affected most if not all planets. Computer simulations modelling a giant impact are consistent with measurements of the angular momentum of the Earth–Moon system, as well as the small size of the lunar core. Unresolved questions regarding this theory concern the determination of the relative sizes of the proto-Earth and Theia and of how much material from these two bodies formed the Moon.

I had no idea the crescent moon looked different in the southern hemisphere. Now I have to figure out how I can drop that tidbit into conversation. (only kidding) But it really is interesting!

I did not realise that the moon took different shapes in different parts of the world. Thank you for showing this. I enjoyed reading it and thinking about it.

Magical picture!

Reader Wil said...

Thank you all for your kind words. The photos are not splendid, but as we all see the moon and watch its different shapes, I thought it would be nice to tell you that we( my daughter, son-in-law and I) were very surprised to see it like this. My Australian daughter was of course not surprised at all. I answered each of you on your blogs only rhoen I couldn't, because I cannot find a way to comment, but I like your blog rhoen!

Great job! "Louis" was trying to capture an image of the moon two nights ago and gave up - he just couldn't get the settings right...

Always a wonder for me to watch the moon, think about its history and then to recall that south of the equator it faces the opposite. What an interesting post.

Hello again Reader Will. I too have read the Kite Runner - wonderful. Love your sky watch pictures! Nice to make contact -let's keep it up. You ask about my husband - he was what used to be called in U K a "boy soldier" and was sent to Shanghai with a military band in 1938 and was taken prisoner in Singapore shortly after the outbreak of war. But he - like you - was a survivor and put it behind him once he returned to UK and lived to be 66 - in good health until the year of his death.
