Well, I'm not inclined to explain (since it would violate the Prime Directive of time travelers). I'll only point out a few details: I posted my challenge 11 days before the APOD showed up, this was a first run image, and there were at least two APODs in the intervening time that listed "open space" for the following day, meaning that TPTB had not yet decided what to run (and I don't think they plan out more than a few days ahead, in any case). And for the record, I had no contact with the author of the image in advance, nor with the APOD editors.owlice wrote:(The correct answer)
I think someone has some explaining to do!
If nothing else, this should demonstrate the difficulties in trying to find time travelers by looking at computer records (or it supports finding them, as you prefer).
