Here, in Venice, the “Devil” is (definitely) in the detail. The new metal door recently installed in the much older building, though a little out of place, appears perfectly functional and looks like it is good operating condition.
What needs to be pointed out here is that Venice, Italy is a city, situated just a few feet above sea level and so those cracks in the wall may be caused by the overwhelming presence of sea water in the immediate vicinity.
Furthermore, Venice may also be a bellwether locale, for the distinct possibility that our sea levels are rising and this phenomena may be causing and will cause problems along some coastlines in the near future.
There is a great website put up by Robert Nemiroff (MTU) & Jerry Bonnell (UMCP) of NASA called Astronomy Picture of the Day. Everyday a fantastic picture is posted, concerning some sort of visual image from outer space. Sometimes the pictures are even taken from the ground with the naked eye. Other pictures are taken from huge telescopes, while some of the most spectacular images come from the Hubble and other spacecraft.
Images from the NASA can sometimes be used on your blog or website as background graphics or simple images associated with text. Other pictures are copyrighted and one must contact the maker for permission. Since the pictures are all displayed by NASA, I do not see why permission would not be easily granted. Enclosed at the end of this post is a link to the image guidelines. Check out this next photo that was posted by NASA on Halloween 2006.
If you are interested in using NASA images on your web, here are the guidelines.
