Amanda doesn't like this nebula
.she says it's like a brain!
NGC 6888, the Crescent Nebula, very near
to Sadr in Cygnus is thought to have started formation about 250,000 years
At a distance of about 4700 light years, the light that those of us who've
imaged or viewed this have just received left at a time that saw the start
of the bronze age, the beginning of writing and the spread of agriculture.
