A supermassive black hole is found in the center of every galaxy. Still, AGN are more spectacular events actively attracting gas and displaying a brilliance not found in normal black holes.

The JWST survey, which has a greater resolution than previous surveys using the Spitzer Space Telescope, was expected to find many more AGNs. However, despite MIRI’s increased strength and sensitivity, the current survey only discovered a small number of extra AGNs.

Active galactic nuclei, which are supermassive black holes quickly growing in size, were previously thought to be more common. However, a University of Kansas investigation of the cosmos using the James Webb Space Telescope has shown otherwise.

The Mid-Infrared Instrument (MIRI) results on the JWST indicate that our cosmos might be slightly more stable than previously thought. The study also discusses the difficulties in finding AGN and observations of faint galaxies and their characteristics.
