The Sombrero Galaxy has undergone a significant transformation. New images from the Cerro Tololo Inter-American Observatory in Chile reveal an enormous halo surrounding the galaxy, stretching about 150,000 light-years across. This halo makes the already large object in the Virgo Galaxy Cluster appear even more expansive. The images were captured using the Dark Energy Camera on the Victor M. Blanco 4-meter Telescope, which continues to offer fresh insights into cosmic phenomena. NOIRLab notes that this may be the first time the halo has been captured with such detail and scale. Discovered in 1781 by Pierre Méchain, the Sombrero is a nearly edge-on spiral galaxy located about 30 million light-years from Earth. It’s best known for resembling a Mexican hat, with a central bulge and a dark dust lane. Recent observations highlight a faint but vast stellar stream on the galaxy’s south side, suggesting a past interaction with a smaller galaxy.
