Question

A spiral galaxy can be described as _____________

Answer 1

A spiral galaxy can be described as a type of galaxy characterized by its flat, rotating disk containing stars, gas, and dust, along with a central concentration of stars known as the bulge. The spiral structure is formed by winding arms that extend outward from the center, typically rich in young stars and stellar nurseries. These galaxies often showcase a variety of colors due to the presence of both young, blue stars and older, red stars. Notable examples of spiral galaxies include the Milky Way and the Andromeda Galaxy.
