Question

1. explain why understanding nucleosynthesis helps astronomers learn about distant stars.

Explanation:

Nucleosynthesis is the creation of atomic nuclei. Stars are made of elements formed through nucleosynthesis. By studying nucleosynthesis, astronomers can understand the elemental composition, age, and life - cycle stages of distant stars. Spectroscopy of starlight reveals the elements present, which are products of nucleosynthesis processes.

Answer:

Understanding nucleosynthesis helps astronomers learn about the elemental composition, age, and life - cycle stages of distant stars as stars are composed of elements formed through nucleosynthesis processes and spectroscopy of starlight can reveal these elements.
