... It should be possible to achieve a thorough understanding of the ways in which stars have fonned in our galaxy over its lifetime of 101 a years, as well as an understanding of the history of the enrichment of our galaxy in ele· ments heavier than hydrogen that resulted as stan exploded and spewed newly formed elements Into interstellar space. By the time the sun condensed 5 X 109 years ago, enough heavy elements had been fonned to provide the solid materitlthat eonstitutes the solar system, including planet Earth, with Its potentiJIIity for life.

... including vavitational collapse into huge black holes, explosions of mal5ivo stars, and acceleration of particles by large number> of pulsars, these theories are difncuh to test because of current limitations of waveltnJth coverage and angular rooulion. The Ltrge redshifis of quasars have made it possible in many eases to study the far uv spectra from the ground: for quasar> with z"' 2,the lyman" line appears at 3648 A; for z: 3, the Lyman limit is easily visible.
