Explanation: These dark markings on the sky [5]  can just be found in
silhouette against a rich, luminous background of stars. Seen toward the
southern constellation of Lupus the Wolf, the dusty, obscuring clouds are part
of the Lupus Molecular Cloud some 500 light-years distant. Packs of low mass
stars are forming within them [6] , from collapsing cores only visible at long
infrared wavelengths [7] . Still, colorful stars in Lupus add to this pretty
galactic skyscape [8] . It spans about 8 degrees, not far from the central
Milky Way.
