Located in the constellation of Sagittarius, the Lagoon Nebula may be one of the most widely observed objects in the nighttime sky. To the unaided eye it appears as a faint patch of cloud that is buried amongst a sea of stars. This emission nebula resides 5,800 light-years away from Earth, and is a very well known region of stellar birth. This area is 3 to 4 times more fruitful in massive star production than other regions.

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.

Messier 82 is an active starburst type galaxy located approximately 12 million light-years from our Milky Way. Messier 82 has a bipolar outflow of material streaming from its galactic nucleus. This outflow, also known as a superwind, is thought to be fueled by supernova explosions.   A supermassive black hole is known to reside in the core of this edge-on galaxy.

The Bubble Nebula is located 7,800 light-years from Earth towards the constellation Cassiopeia. NGC7635 is surrounded by a vast HII molecular cloud that glows red as hydrogen atoms are ionized.  Young stars are forming in some of the globules depicted in this image. These globules form as parts of the molecular cloud collapse and continue to contract under their own gravitational force.

NGC891 is an edge-on spiral galaxy located in the constellation Andromeda. It was discovered in 1784 by William Herschel. The galaxy lies 30 million light years from our own Milky Way. Infrared observations of NGC891 suggest that it may be a barred spiral galaxy, but its orientation prevents us from seeing the bar in visible light.

Considered one of the most photographed objects in the sky, the Horsehead Nebula resides 1,500 light-years from Earth in the constellation of Orion. This dark nebula represents a cloud of dust and non-luminous gas that appears to represent a horse’s head. Williamina Fleming, one of the most renowned female astronomers ever, became the first person to observe the horse head like structure on a photographic plate.

The Space Shuttle Discovery carried 252 astronauts and 31 satellites into space. One of its more famous payloads, the Hubble Space Telescope, was deployed in 1990. Discovery was in service from 1984 to until 2011. It traveled over 238,000,000 km before its retirement. Since its decommission, Discovery has been place on permanent display at the National Air and Space Museum’s Udvar-Hazy Center in Virgina.
