I too am quite skeptical of the "debris" photograph. I guess it's possible that with highly angular setting or rising sunlight that debris could be lit in such a way. One would have to assume the photographer is capable of recognizing what are lit city lights and what are something that looks out of the norm - and hence why they brought it to outside attention. Additionally it does appear the shot was taken in the early morning according to reports.
On the flip-side it could also be completely bogus.
