2.4 million light-years from Earth, the Triangulum Galaxy resides in the constellation Triangulum and spans some 50,000 light-years. This galaxy contains roughly 40 billion stars and is the third largest galaxy in the Local Group. M33 contains many star-forming regions, and these regions are represented by the color red.

The Sombrero Galaxy as seen through 200″ Hale Telescope.

The Sombrero Galaxy is an edge-on spiral galaxy located 28 million light-years from Earth. It resides in the constellation Virgo within a filamentous complex of galaxies known as the Virgo Supercluster. The Sombrero Galaxy has between 1,200 – 2,000 globular clusters in its halo, more than usual for a galaxy of its luminosity.

A symmetrical dark lane composed of mostly cold dust and molecular hydrogen encapsulates the central bulge of this galaxy. At the center of the galactic disk lies a “low ionization nuclear region” where atoms are weakly ionized by the supermassive black hole that powers M104’s active galactic nucleus.
