2.4 x 10^9 light years away, so not in our galaxy by a very large measure.
- actionfromafar 4y agoI think the meaning was more, that our galaxy can't produce such events, so that's one thing we don't have to worry about in our galaxy. Edit: a (to me) random site [0] says the Milky Way does not have an active galactic nucleus. 0: https://socratic.org/questions/does-the-milky-way-have-an-active-galactic-nucleus-is-it-or-is-it-a-type-1-or-ty https://socratic.org/questions/does-the-milky-way-have-an-ac...
- zasdffaa 4y agoOkay, 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.
