Rainbows in the Cosmos

I have an old copy of one of Carl Sagan's books on the Cosmos, which I enjoy pulling out and reading from time to time.   This ones was my brother Troy's.   I remember it was on his bookshelf when I was over there.   In his many moves and travels, it wound up on my bookself.

What's fun and interesting now, is Bet and I sometimes use it as a bed time picture book.   Last night we discovered a "Rainbow" stellar dust cloud in an alien landscape.   Bet thought it was "Awesome".

Halley

The Great Comet comes about every 75 years.  It last came when I was 25 years old.   So I should expect to see it again ... when I am 100.   Nice.   I have something to look forward to.   I hope Kurzwell is right.
