Azathoth?
I've never heard of this thing being called Azathoth--Dans1120 00:27, 8 October 2006 (UTC)

Eric Bacalin
According to a National Geographic program, Eric Bacalin discovered Sagittarius A on 1966. I can't find a source. Would anyone care to try? Thanks Kvsh5 (talk) 15:15, 13 February 2010 (UTC)

Mass is off
Sag A* alone is 4.3 million solar masses. So how can Sag A be only 3.8 million solar masses.

I also support that statement, the mass of Sag A* is estimated to be between 4 and 4.7 solar masses so the source of radio emissions must be higher. Smulumudi (talk) 00:09, 9 June 2011 (UTC)

NuSTAR section is incomprehensible
The NuSTAR section requires a rewrite: it's unclear to me what the actual findings were (in layman's terms), what the role of NuSTAR war (the paragraph talks about observations made by Chandra, not NuSTAR). Also, the units look odd: 10$16$ centimeters instead of mm or m? The referenced paper is (also) available on Arxiv: NuSTAR detection of high-energy X-ray emission and rapid variability from Sagittarius A* flares Stefan Bethke (talk) 08:28, 6 December 2014 (UTC)
 * After reading the paper, I still don't understand. Unless an expert can provide a good summary, including the significance of the findings, I suggest removing this section. The same goes for the Dark Matter section. Stefan Bethke (talk) 08:49, 6 December 2014 (UTC)
 * After locating and reading the reference for Sagittarius a-element knee (see arxiv), I think the paper is talking about an entirely different object. Unless someone steps up and confirms the connection between the Sagittarius galaxy and Sgr A, I suggest to remove all contributions by User:08C ext2013 talk from this article.

What are its galactic coordinates -
Could the infobox include the galactic coordinates (more clearly) so we can place it on the chart in Sagittarius_(constellation) ? - Rod57 (talk) 17:32, 16 December 2017 (UTC)


 * Sounds like a good idea. Is anyone out there listening? — Preceding unsigned comment added by 184.170.161.43 (talk) 14:50, 28 January 2022 (UTC)


 * Done as requested. BFG (talk) 15:19, 28 January 2022 (UTC)

Sagittarius spiral arm (may not belong in this article)
This section should perhaps be moved to the Structure of Milky Way ? - Rod57 (talk) 17:39, 16 December 2017 (UTC)
