Largest Known Galaxy Spans 1.7 Million Light-Years Across

In the depths of the observable universe, astronomers have identified a galaxy stretching 1.7 million light-years across — seventeen times the breadth of our own Milky Way — confronting humanity once again with the humbling truth that the cosmos routinely exceeds the boundaries of our imagination. This discovery is not merely a record broken but a question posed: by what processes does matter assemble itself into structures so vast that light itself requires nearly two million years to traverse them?
