Two images of Cygnus A layered over each other to show the galaxy’s jets glowing with radio radiation (shown in red). Quiescent galaxies, like our own Milky Way, do not have jets like this, which may be related to magnetic fields.

Quiescent galaxies, like our own Milky Way, do not have jets like this, which may be related to magnetic fields. The yellow image shows background stars and the center of the galaxy shrouded in dust when observed with visible light. The area SOFIA observed is inside the small red dot in the center.
