Image Description and Details :

LDN 673 (Lynds’ Dark Nebula 673) is a highly fractured and very dense dark cloud complex about 600 light-years from Earth in the constellation Aquila. It is located near the center of the Aquila Rift, a great mass of dark molecular clouds along the summer Milky Way through the constellations Aquila, Serpens, and eastern Ophiuchus. This molecular cloud make the distant stars appear reddish, while the very dense LDN 673 nebula completely blocks the starlight.

In silhouette against the Milky Way’s faint starlight, LDN 673’s dusty molecular clouds likely contain raw material to form hundreds of thousands of stars. Visible indications of energetic outflows associated with young stars include the small red tinted nebulosity RNO 109 (GN 19.18.0) and several Herbig-Haro objects, like HH 32 near the young variable T-Tauri star V1352 (AS 353). These objects are signs of active star formation.
