Meet LEDA 1205871 and LEDA 29228, two of the hundreds of thousands of galaxies captured in NSF–DOE Rubin Observatory’s deep COSMOS image. In particular, these two are "shell" galaxies surrounded by arcs that form when a large galaxy absorbs a smaller one. Shell galaxies are tough to spot, but NSF–DOE Rubin Observatory's deep imaging will uncover more! Scientists will be able to trace the collision history of galaxies and study how they grow over time🌌🌊 What is a Shell Galaxy? A shell galaxy is a rare type of galaxy surrounded by faint, concentric arcs or "shells" of stars. like, LEDA 1205871 and LEDA 29228, captured in deep imaging data from the NSF–DOE Vera C. Rubin Observatory's COSMOS field survey. These delicate stellar ripples are notoriously difficult to detect because they are extremely faint compared to the galaxy's bright central core. These intricate structures are cosmic fingerprints of past gravitational encounters, typically cr...
