I was playing around with the New NASA pic of earth (posted July 20th 2015 on Nasa Goddard space flight center on Flickr). I've found this very odd structure on the bottom right corner that is pretty much hidden in the darkness. There must be some kind of un-spectacular reason for this to look like a barber's pole, henceforth, this image will be named "Nasa's barber pole" until proven through some ultra-complicated computer mathematics.
I'm asking photographers because I would like a point of view from people who work with images either through Photoshop or whatever, Are these type of anomalies normal? Has anyone else noticed these things?
