The accretion disk of NGC 4151 is shown in blue, immediately surrounding the galaxy’s central black hole. Scientists, including University of Michigan astronomers, are showing how winds or outflows from the accretion disk reshape its host galaxy. The winds are shown as wispy light blue lines blowing across the more orange clouds surrounding the black hole. Image credit: JAXA (Used under a CC BY 4.0 INT license)
