The youngest stars in a spiral galaxy are generally found in the the halo the disc the bulge

## Step 1<br />Spiral galaxies are characterized by their spiral structure, which is a result of the distribution of stars, gas, and dust within the galaxy. The galaxy is divided into several parts: the halo, the disc, and the bulge.<br /><br />## Step 2<br />The halo is the spherical region surrounding the galaxy, containing older stars and globular clusters. It is not the primary location for the youngest stars.<br /><br />## Step 3<br />The disc is the flat, spiral-shaped region of the galaxy. It contains the youngest stars, as well as gas and dust that are the raw materials for star formation. The spiral arms of the galaxy are part of the disc, and they are the sites of active star formation.<br /><br />## Step 4<br />The bulge is a region of the galaxy that is denser than the disc but not as dense as the halo. It contains older stars and is not the primary location for the youngest stars.
