The Vera C. Rubin Observatory in Chile has captured an image of the COSMOS field, a region of the sky previously studied by the Hubble and Webb telescopes. The central panel of the image shows more than half a million galaxies, with outer panels providing detailed views of selected areas. The COSMOS field was chosen for its relatively clear view of distant galaxies, as it contains few bright stars from our own Milky Way.

The image highlights the variety of galaxy shapes and sizes, including some so distant that their light has traveled billions of years to reach Earth. The Rubin Observatory's advanced capabilities allow it to observe these galaxies in unprecedented detail. The outer panels, numbered 1 through 10, zoom in on specific regions within the central panel, showcasing the diversity of galactic structures.

The Rubin Observatory will revisit the COSMOS field every few days as part of its ten-year Legacy Survey of Space and Time. This survey aims to provide a dynamic view of the field, tracking changes in the sky over time. The repeated observations will help astronomers study the evolution of galaxies and the universe.

The COSMOS field was first observed by the Hubble Space Telescope and has since been studied by multiple observatories. Its selection for the Rubin Observatory's survey is due to its unique characteristics, offering a relatively unobstructed view of distant galaxies. The new image and survey will contribute to ongoing research in astronomy and cosmology.
