We are now in day two of Chinese year 4710.  The Chinese use a lunar calendar (although in business they usually use the Gregorian calendar like most of the rest of the world), and the first of every month is the darkest night of the month, or the night with the new moon.  For more information click here and click here.

The First Photograph of the Moon


The earliest extant photograph of the moon:  Draper, John W., “First Astronomical Photograph - Draper's Moon Daguerreotype,” Greenwich Village History, accessed January 6, 2012, http://aphdigital.org/GVH/items/show/119.

On this day in 1839, French photographer Louis Jacques Mandé Daguerre (17891851) took the first photograph of the moon.  This photograph was burned in the March 8, 1839 fire that destroyed Daguerre's laboratory.  The photograph was actually a daguerreotype, an early method of photography named after Louis Daguerre.  During this photographic process a silver-coated copper plate is treated with iodine vapor.  Prior to this invention, pictures of the moon for texts and articles had to be drawn by hand.

My favorite moon photos are those with astronauts walking around, because they make me imagine what that might feel like.  What are your favorite moon photos?

November 26 and 27 are great nights for sky-watching in the northern hemisphere.  There is a conjunction between the moon and Venus.  For more information click here.

If you're in the southern hemisphere, did you get a look at the last solar eclipse for 2011 on November 25?
