Sombrero galaxy
Caption: This prominent galaxy M 104 is often called the Sombrero galaxy due to its resemblance to the Mexican hat. This look is created by the thin disk oriented nearly edge-on, which appears illuminated by the dominant bulge. Both, the disk and bulge contain stars, but the stars in the bulge tend to be older, while the disk also harbors large amounts of dust and gas creating shadows. M 104 is located in the constellation Virgo approximately 50 light-years away. While some of the dots visible in the picture are foreground stars and others background galaxies, the majority are actually globular clusters, dense massive clusters of stars, associated with the Sombrero Galaxy.

A visible light image of the Andromeda Galaxy
Caption: The Andromeda Galaxy viewed in visible light. Like our Milky Way, Andromeda is a barred spiral galaxy. Here we can see its bright core and spiral disk. The glow from the stars in the disk is interrupted by lanes of dust that form part of its spiral structure.
Andromeda is the largest galaxy in the Local Group of galaxies that includes the Milky Way.
To the left of the core and just above the disk we see the dwarf galaxy M32 and to the right and below the disk we see the dwarf galaxy M110. These are both satellite galaxies of the Andromeda Galaxy.

The Lenticular Galaxy NGC 2787
Caption: The lenticular galaxy NGC 2787. This galaxy is a disk galaxy but lacks the large, dominant spiral arm structure seen in the disks of spiral galaxies. Its core is very bright compared to the core of a spiral galaxy. Thin rings of dust can be seen in the galaxy's disk.
