Re: APOD: Meteor Misses Galaxy (2024 Jul 14)
Very lucky guy Indeed. I am curious to hear whether the APOD editors had heard of the shooting before choosing the image for this day? SInce Sundays are typically "reruns" and the process for choosing what to rerun may be to a degree automated at an earlier time, I think it is possible an...
