Last night, during late-night drive, while there was nothing listenable on the usual radio stations, I turned on "Coast-to-Coast" on the radio (Late night AM radio talk program about "paranormal" things). There was some "expert" who was talking about this blackhole image: "This is not exactly a photograph... It is an image that is made [up] based on the data, ..." (Which is true in the very strict meaning of the word "photograph", if you consider the origin of the word photography, - from Greek "photos" meaning "light". Wavelengths used for the image are far from the visible light spectrum.)


That reminded me of some similar statements by "purists" among photographers about what constitutes an unaltered [digital] photograph, i.e. how processing an image makes it not a "true photo".

The best bit is the narration accompanying the *simple explanation video*...

"... black holes are extremely hard to see."

Ya' think? It's black and it's 55 million light-years from Earth!


Also: It's HUGE! https://xkcd.com/2135/
