QUASARS, PULSARS, AND BLACK HOLES

Before the scientific developments of the last 50 years, the Universe seemed a quiet, unchanging place. But mysterious things have happened among the stars for billions of years. Isaac Asimov examines the factual and theoretical nature of such stellar phenomena as quasars and black holes. In so doing, he helps readers discover how tumultuous our seemingly tame Universe can be.

This is a very good little book for younger readers. Adults would probably prefer the less copiously illustrated Collapsing Universe, however.
