Carl Sagan died December 20th, 1996. The short paragraph at the top of the page says 1997. The least we can do is get the date of his death right. Cosmos is wonderful, one of a great man's greatest works.
I am just 15 years old and i've read this book almost five times filnding a different meaning to it each time. This book has given me the bases to study astronomy and I recomend you should really read it.
