An incredibly bright star has lost its gas and is just a leftover core

One of the brightest stars we see in the night sky has lost its outer layers of gas and now it is just a rare, stripped-back core

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.
