Lynds Dark Nebula (LDN) 673 is a prominent dark nebula situated within the Aquila Rift, a region rich with interstellar dust and gas clouds. Spanning approximately 7 light-years across and located about 600 light-years from Earth, LDN 673 is a complex structure that obscures the light from background stars, creating an intricate tapestry of dark and light patches in the night sky. This dense molecular cloud is a site of active star formation, with numerous young stellar objects hidden within its veils of dust.

The Aquila Rift itself is a significant feature of the Milky Way, appearing as a dark band that bisects the bright star fields of the constellation Aquila. The rift's dark clouds, including LDN 673, are part of a larger network of star-forming regions that contribute to our understanding of the processes involved in stellar evolution. Observations of LDN 673 and its surroundings provide valuable insights into the initial conditions of star formation and the dynamics of interstellar matter.
