Further Study....
This manual gives only the briefest introduction to astronomy. If
you are interested in pursuing further studies in astronomy, a few
topics are suggested below that are worth reading up on (some
of the topics are easy and some are quite challenging). Try look-
ing up some of these in the AutoStar glossary.
Also included below is a small sampling of books, magazines
and organizations that you might find helpful.
Topics
1. How is a star born? How does a solar system form?
2. How is the distance to a star measured? What is a light
y
ear? What is red shift and blue shift?
3. How are the craters on our Moon formed? Is there water
under the surf
ace of the Moon?
4.
What is a black hole? A neutron star? A quark star? A
gamma burster? An Einstein lens?
5. What are stars made of? Why are stars different colors?
How is the elemental composition of a star determined?
What is an Lyman Alpha forest?
6. What is the difference between a Type 1 and a Type II
supernova?
7. What is the importance of studying the composition of
comets? Where do comets come from?
8. How old is our Sun? Will our Sun evolve into a planetary
nebula or go supernova?
9. What is the Inflationary Big Bang? What is dark matter?
What are MACHO's?
10. How are extrasolar planets discovered? What is an accre-
tion (or protoplanetary) disk?
11. What are the differences between elliptical, spiral and irreg-
ular galaxies? Can globular clusters be older than the uni-
verse itself?
