You deleted my reference to the Seyfert status of the galaxy in your efforts to remove the remainder of my dull comments.  For people unfamiliar with the subject matter a brief explanation of the picture was thought to be helpful (boring as it may have been).  If the Seyfert status is wrong, I could care less, but it was sourced from this article: "NGC 1672 is a member of the family of Seyfert galaxies, named after the astronomer, Carl Keenan Seyfert, who studied a family of galaxies with active nuclei extensively in the 1940s. The energy output of these nuclei can sometimes outshine their host galaxies. The active galaxy family include the exotically named quasars and blazars. Although each type has distinctive characteristics, they are thought to be all driven by the same engine – supermassive black holes – but are viewed from different angles."
