The Radio Arc is connected to the Galactic Center by strange curving filaments known as the Arches.

The bright radio structure at the bottom right surrounds a black hole at the Galactic Center and is known as Sagittarius A.

One origin hypothesis holds that the Radio Arc and the Arches have their geometry because they contain hot plasma flowing along lines of a constant magnetic field. Images from NASA’s Chandra X-ray Observatory appear to show this plasma colliding with a nearby cloud of cold gas.
