Astronomers using NASA’s Chandra X-ray Observatory have made a groundbreaking discovery in the galaxy cluster known as Zwicky 8338 (Z8338). Located about 670 million light-years from Earth, this cluster contains two distinct streams of superheated gas crossing each other—a rare and complex phenomenon that sheds light on how galaxy clusters evolve. This unusual event provides crucial insights into the dynamics of galaxy clusters, offering a window into the interactions between galaxies and the surrounding hot gas, which is critical for understanding galaxy formation and evolution on a larger co…
