Spiral galaxies such as NGC 275 have a central band of stars running through the bulge, appearing in the image as a bright white vertical haze. Spiral arms often extend from the ends of the strip.
Lenticular galaxies such as NGC 274 are structurally located between elliptical and spiral galaxies. They get their name because they resemble a disk in appearance, having large central ridges and flattened disk-shaped spirals, but no prominent spiral arms. Lenticular galaxies are characterized by a scarcity of gas and dust and consist mostly of aging stars.
