The Vera C. Rubin Observatory’s 3.2-gigapixel Legacy Survey of Space and Time (LSST) camera has captured a single image containing more than 650,000 galaxies, according to a report from PetaPixel. The image also includes over 50,000 stars, as noted by the outlet.
The photograph focuses on the COSMOS field, a well-studied patch of sky used for deep extragalactic surveys. PetaPixel reports that the image was released as part of ongoing commissioning work for the camera, which is the largest digital camera ever built for astronomy.
The COSMOS field is a standard target for astronomers because it offers a dense, wide view of distant galaxies. Gizmodo, which also covered the release, noted that the image reveals the field in unprecedented detail, helping scientists test the camera’s ability to capture faint objects across a broad area. The Rubin Observatory’s own materials describe the image as a demonstration of the camera’s full field of view, which is designed to survey the entire southern sky repeatedly over a decade.
According to The Times of India, the image represents one of the deepest single exposures of the universe taken to date, with the camera capturing light from galaxies billions of light-years away. Yahoo also highlighted the scale of the image, noting that the 3,200-megapixel resolution allows for sharp views of individual galaxies even in a crowded field.
The LSST camera is central to Rubin Observatory’s mission to map the night sky, track moving objects, and study dark energy and dark matter. The current image is a test of that capability, not yet part of the main survey.
Watch for the start of the full ten-year survey, which is expected to begin after commissioning finishes.
