Quizplus · Accepted Answer

The statement is true. The pink color tracing the spiral arms of a galaxy is usually from emission nebulae, which are clouds of ionized gas that emit light at specific wavelengths. This light is often visible as pink, red, or orange, depending on the specific atoms and molecules present in the nebula. Examples of emission nebulae in spiral galaxies include HII regions, which are ionized hydrogen clouds, and regions of star formation, where young, hot stars ionize the surrounding gas.
