A gigantic halo surrounds the Sombrero Galaxy in new telescope images

The famous Sombrero Galaxy now appears as more than a wide-brimmed hat floating in deep outer space. New images from the Cerro Tololo Inter-American Observatory in Chile reveal a gigantic halo surrounding the galaxy, stretching three times its width. Already considered one of the largest objects in the Virgo Galaxy Cluster, the galaxy's expansive glow is roughly 150,000 light-years wide. The pictures come from the Dark Energy Camera, an instrument mounted on the U.S. National Science Foundation's Victor M. Blanco 4-meter Telescope. Though the camera was built for a study that ended in 2019, it continues to aid astronomers, providing new insights for even the most photographed cosmic targets. "This may be the first time the halo has been captured with this level of detail and at this large a scale," according to NOIRLab, a program of the National Science Foundation. Discovered in 1781 by the French comet hunter Pierre Méchain, the Sombrero is a nearly edge-on spiral galaxy about 30 million light-years away from Earth in the Virgo constellation. Méchain was an associate of renowned astronomer Charles Messier, but the object was only scribbled onto Messier's personal copy of the Messi
