Seyfert II

It is flatly stated that Seyfert II "means that a supermassive black hole.." etc. etc. This is flatly not so - being a Seyfert has nothing to do with how it is explained, rather what is observed. — Preceding unsigned comment added by Antimatter33 (talk • contribs) 20:16, 7 September 2012 (UTC)

File:Messier 106 visible and infrared composite.jpg to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Messier 106 visible and infrared composite.jpg will be appearing as picture of the day on October 10, 2017. You can view and edit the POTD blurb at Template:POTD/2017-10-10. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. — Chris Woodrich (talk) 01:52, 24 September 2017 (UTC)

Picture of the day

Messier 106 is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years from Earth. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center.Photograph: NASA, ESA, Hubble Heritage Team, and R.

Vague in the lede

Lede states "Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center." What is "unusual"? Do we not expect infall into most SMBH cores? LeadSongDog come howl! 16:49, 10 October 2017 (UTC)

Just made a few changes after noticing this too. The X-ray emission and emission lines are not unusual for a Seyfert 2 galaxy, these are standard features for an AGN. It's better to just describe it as an AGN with links to the appropriate pages, and I added some information on the black hole detection in the lead section since this is one of the most important galaxies for demonstrating the existence of supermassive black holes.
