Okay, missed that. https://en.wikipedia.org/wiki/Active_galactic_nucleus https://en.wikipedia.org/wiki/Active_galactic_nucleus says
"An active galactic nucleus (AGN) is a compact region at the center of a galaxy that has a much-higher-than-normal luminosity over at least some portion of the electromagnetic spectrum with characteristics indicating that the luminosity is not produced by stars. Such excess non-stellar emission has been observed in the radio, microwave, infrared, optical, ultra-violet, X-ray and gamma ray wavebands. A galaxy hosting an AGN is called an "active galaxy". The non-stellar radiation from an AGN is theorized to result from the accretion of matter by a supermassive black hole at the center of its host galaxy."
Do we? https://en.wikipedia.org/wiki/Sagittarius_A\ https://en.wikipedia.org/wiki/Sagittarius_A\* says
"Sagittarius A*, abbreviated Sgr A* is the supermassive black hole[4][5][6] at the Galactic Center of the Milky Way"
Front row seat! Get in!
- codethief 4y agoSgr A* isn't a very active black hole (meaning that it's accreting only very little matter), compared to black holes at the center of AGNs.
