I subscribed to an online Page-A-Day calendar last year, and for Valentine's, they gave me a code to subscribe to one for free this year. So I opted for the Fact or Crap calendar. Browsing January, I got the answer to a puzzlement: Why do you see the whole moon even when it's new? Y'know, you look up, see that bare line of a crescent, but can also make out the rest of the circle, the rest of the moon. Why isn't the dark part completely invisible? Earthshine, that's why. Just like the moon, the Earth reflects sunlight, too - enough to let you make out the whole moon even when it's dark. The strength of the earthshine depends on Earth's cloud cover. I knew the Earth reflected light, like the moon, if not as well; I just never realized that was why a new moon is visible. UPDATE: There was a derailment in the comments; two trains of thought couldn't stay on the same track. My American pop culture references do not extend to TV-series of the 1950...

I like the composition of the photograph, with the barren trees and the snow and just a hint of blue in the sky.
Looks like a very beautiful church from outside; and I am sure it is inside as well.;)
I like spots like this a lot!
Beautiful shot as well.
Happy WW! :)
An(n)onymous, we were in domkirken. I don't think we went inside Mariakirken at all.
Thanks, Nicole! I see this view every time I go to the hair dresser's. :-)
