With the creation of Celestial Bodies V–Z, I have now completed all 26 in this series, one for each letter of the alphabet. You can see that the image for the letter “X” is a comet, named x/1702 because it was observed in the year 1702. There were only two letters of the alphabet which were difficult to find objects for: “X” and “Q.” For “Q” I used a Chinese name for a particular star. Otherwise, the sky (and the human habit of naming things) has been very cooperative with my alphabetic imagination. Most of the names are from the Arabic, and I love how they sound.
