Vmedvil Posted December 12, 2017 Share Posted December 12, 2017 (edited) 23 hours ago, Airbrush said: The center of galaxies, and along the spiral arms, have more heavy elements than the outer and less dense regions because there are more giant stars packed closer together near the center of the galaxy that go supernova and scatter their heavy elements around. Earth is in the galactic habitable zone because it is far enough away from the center of the galaxy with the deadly radiation but still close enough to populated regions to get enough heavy elements from supernovas. That is so very True our SMBH in the milky Way Sgr A does have much Iron "Blue part" around it a Iron Nebula about 5 by 5 ly of it on cross section.

Nothing in there about an "iron nebula" (whatever that means) or even "blue". But it does (not surprisingly) confirm the presence of iron (and other elements).

John Cuthber Posted December 12, 2017 Share Posted December 12, 2017 (edited) I see an image showing where Xrays are emitted from. Nothing to do with iron; almost any element will emit xrays if it's hot enough. Edited December 12, 2017 by John Cuthber Link to comment Share on other sites More sharing options...

I might have to annoy the moderators by reporting every case where you post unreferenced material. Still no evidence it is a "cloud of iron gas" (which is not the same as a could containing a number of elements including some iron). Link to comment Share on other sites More sharing options...

Vmedvil Posted December 12, 2017 Author Share Posted December 12, 2017 (edited) It is near a SMBH of course it is plasma or gas, calculate what the gravity must be near a rotating 31.6 R☉ SMBH is. In any case, here is the Newtonian way to calculate that for me being lazy. Fg = GM1M2/R2 M1 = Mmass BH + (EAngular BH/C2) Eangular = (1/2)Iω2 Note convert to meters and kilograms. Mmass BH = (4.31 ± 0.38) × 106M☉ ω = 46 km/s Edited December 12, 2017 by Vmedvil Link to comment Share on other sites More sharing options...

Fine, a "Nebula that is at-least partially Iron or contains some amount of Iron" on the east side which is atleast 5 ly by 5 ly of Iron Spectral lines.
