Looking very much like a deadly virus, LDN 673 is located in the constellation Aquila. This dark nebula, at a distance of about 600 light years, is in a dark rift in the Milky Way that passes through the constellation. Expansive molecular clouds in the Aquila rift make the distant stars appear reddish, while the very dense LDN 673 nebula completely blocks the starlight.
