Physics Galaxy Discussion Questions Solutions -

Spiral galaxies, like the Milky Way, are characterized by a central bulge and a disk of stars, gas, and dust, with spiral arms of younger stars and star-forming regions. Elliptical galaxies, on the other hand, are egg-shaped and lack a disk, with a higher proportion of older stars and less gas and dust.

When immersed in a medium with a refractive index closer to its own, a lens's converging power decreases, significantly increasing its focal length. Spiral galaxies, like the Milky Way, are characterized
