Part of a dark expanse that splits the crowded plane of our Milky Way galaxy, the Aquila Rift arcs through the northern hemisphere's
summer skies near bright star Altair and the Summer Triangle. In silhouette against the Milky Way's faint starlight, its dusty
molecular clouds likely contain raw material to form hundreds of thousands of stars and astronomers eagerly search the clouds
for telltale signs of star birth. This telescopic image looks toward the region at a fragmented Aquila dark cloud complex
identified as LDN 673. The dark clouds in Aquila are estimated to be some 600 light-years away.
At that distance, this field of view spans about 290 light-years.
