Images of lenticular galaxies
Lenticular galaxies are composed of a bulge similar to those of elliptical galaxies, placed at the center of a disk. The bulge and the disk are composed of old stars.
The disks of lenticulars do not contain any spiral arms, contrary to spiral galaxies. Depending on their orientation on the sky, we see them face-on, inclined or edge-on.
