Quiz
{SN 1961F is in NGC? { 3003 (i) }.
 * type="{}"}

{Which of the following are attributes that make Type Ia supernovae potentially valuable standard candles? - occur in dusty regions + present in the old stellar populations of all galaxies - they have characteristic mottling + they lack hydrogen lines in their optical spectra + they lack helium lines in their optical spectra - have incipient resolution + during the first month after maximum light they do have a strong absorption feature produced by the red doublet (λ6347, λ6371 Å) of singly ionized silicon
 * type="[]"}

{Supernovae of Type Ia lack hydrogen lines and helium lines in their optical spectra; during the first month after maximum light they do have a strong absorption feature produced by the red doublet (λ6347, λ6371 Å) of singly ionized? { silicon (i) }.

Hypotheses

 * 1) Distances are only as relative as the time it takes to travel them.
