Saul Don't know what you are referring to with my being 200,000 years
old. The Crab Nebula is a famous remnant of a supernova explosion that
was observed and documented by Chinese astronomers in 1054(before my
time) Yes I have enlarged pictures of these explosions plus the Cygnus
Loop ,and that supernova occurred some 15,000 yeas ago. I'm big on the
great explosions with their implosions for I know they created heavy
elements needed to create life. Well Saul I'm old,but when I
was 8 I had more brains then you. Bert
