LXD75 TIPS

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. Try looking up some of these in the optional 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 year? What is red shift and blue shift?

3.How are the craters on our Moon formed? Is there water under the surface of the Moon?

4.What is a black hole? A neutron 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 super- nova?

9.What is the Inflationary Big Bang? What is dark matter? What are MACHO's?

10.How are extrasolar planets discovered? What is an accretion (or protoplane- tary) disk?

11.What are the differences between elliptical, spiral, and irregular galaxies? Can globular clusters be older than the universe itself?
