A visible light image of the Andromeda Galaxy
الشرح: 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.

Hubble Image of Barred Spiral Galaxy UGC 6093
الشرح: This image from the Hubble Space Telescope shows the barred spiral galaxy UGC 6093. This galaxy has two spiral arms in its outer regions but the inner edge of each arm joins with the outer edge of a straight bar feature that goes across the galaxy's center.
This galaxy has been classified as an active galaxy due to the emissions of certain lines in its spectrum. This indicates that the supermassive black hole that lies in the center of the galaxy is accreting gas from its surroundings. Unlike some active galactic nuclei (AGN), the center of this galaxy does not shine especially brightly in the visible light so its status as an AGN is not immediately visible from this image.
