Question

using the apparent magnitude of a certain type ia supernova, astronomers determine that it is 1.7×10^6 pc (or about 5.5×10^6 ly) from the sun. where might this supernova be located? in our solar system in another spiral galaxy in the bulge of the milky way near alpha centauri

Explanation:

The Solar System is much smaller in scale. The bulge of the Milky Way is much closer than 1.7×10⁶ pc. Alpha - Centauri is the closest star system to the Sun and is much nearer. A distance of 1.7×10⁶ pc is typical for another spiral galaxy.

Answer:

in another spiral galaxy
