It has dawned again: The shortest day of the year. With it, the dark season has reached its peak – just like our Christmas puzzle, that goes into the final round today.

 

First, the solution to the last one.

The question:

What is hidden behind this beautifully decorated tree by Manuel Köbrich?

 

The correct answer is: APT-Christmas tree of a Co9Al9W2Pd-alloy with g¢-ornamants and TCP-phase-tinsel

 

And now, most appropriate for the shortest day and thus the longest night of the year, we present this beautiful picture of a starry night sky by Christopher Zenk.

Have fun guessing for the last time!
