Dense, Dusty Cores Up Close! Astronomers have found cosmic clumps so dark, dense and dusty that they throw the deepest shadows ever recorded. The clumps, shown here in a zoom-in detail, were discovered within a huge cosmic cloud of gas and dust. Infrared observations from our Spitzer Space Telescope of these blackest-of-black regions in the cloud paradoxically light the way to understanding how the brightest stars form.

A new study takes advantage of the shadows cast by these dark clumps to measure the cloud's overall structure and mass. These dense, clumpy pockets of star-forming material within the cloud are so thick with dust that they scatter and block not only visible light, but almost all background infrared light as well. The dusty cloud, the results suggest, will likely evolve into one of the most massive young clusters of stars in our galaxy.
