Thousands of stars that exist in this region disappear ? and seemingly endless layers of gas and dust become the centerpiece. The detection of dust by Webb?s Mid-Infrared Instrument (MIRI) is extremely important ? 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. Although the stars appear missing, they aren?t. Stars typically do not emit much mid-infrared light. Instead, they are easiest to detect in ultraviolet, visible, and near-infrared light. In this MIRI view, two types of stars can be identified. 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.

Researchers at SLAC National Accelerator Laboratory are nearly done with the LSST Camera, the world's largest digital camera ever built for astronomy. Roughly the size of a small car and weighing in at three tons, the camera features a five-foot wide front lens and a 3,200 megapixel sensor that will be cooled to -100??C to reduce noise. Once complete and in place atop the Vera C. Rubin Observatory's Simonyi Survey Telescope in Chile, the camera will survey the southern night sky for a decade, creating a trove of data that scientists will pore over to better understand some of the universe's biggest mysteries, including the nature of dark energy and dark matter.
