Mid-Infrared The Pillars Of Creation. Keychain

Mid-infrared view of the Pillars of Creation. Thousands of stars that exist in this region disappear, and seemingly endless layers of gas and dust become the centerpiece. Dust is a major ingredient for star formation. Many stars are actively forming in these dense blue-gray pillars. When knots of gas and dust with sufficient mass form in these regions, they begin to collapse under their own gravitational attraction, slowly heat up, and eventually form new stars. The stars at the end of the thick, dusty pillars have recently eroded the material surrounding them. They show up in red because their atmospheres are still enshrouded in cloaks of dust. In contrast, blue tones indicate stars that are older and have shed most of their gas and dust. Mid-infrared light details dense regions of gas and dust. The red region toward the top, which forms a delicate V shape, is where the dust is both diffuse and cooler.
