Examples[edit]

It may be useful to include examples of far-extragalactic astronomy, and split the topic list between far and near-extragalactic.--Master of Chaldea (talk) 06:10, 21 January 2017 (UTC)[reply]

As it is now, the jump from the examples of near-extragalactic astronomy and the topic list is somewhat abrupt.--Master of Chaldea (talk) 06:17, 21 January 2017 (UTC)[reply]

Comments and Suggestions for Improvement[edit]

"Extragalactic astronomy is the branch of astronomy concerned with objects outside the Milky Way galaxy. In other words, it is the study of all astronomical objects which are not covered by galactic astronomy, and is considered the next level of galactic astronomy." Overall the paragraph is slightly confusing. What exactly is meant by “next level of galactic astronomy”? Also, the entire paragraph structure seems repetitive. Additionally, the definition of extragalactic astronomy could use more detail such as in the description found at http://www.astro.wisc.edu/our-science/research-areas/extragalactic-astronomy/ .

"As instrumentation has improved, more distant objects can now be examined in detail. It is therefore useful to sub-divide this branch into Near-Extragalactic Astronomy and Far-Extragalactic Astronomy. The former deals with objects such as the galaxies of the Local Group, which are close enough to allow very detailed analyses of their contents (e.g. supernova remnants, stellar associations)." It would be helpful if this paragraph gave an explanation as for Far-Extragalactic Astronomy, especially since it includes a brief description of what is meant by Near-Extragalactic Astronomy.

The list of topics include Supernovae, but should this really be a topic? After all, supernovae are part of stellar evolution, regardless of the location of the stars. Also, I think the list could be more refined. For instance, Dark Matter and Active Galactic Nuclei could be added to the list. Finally, I suggest removing Intergalactic dust clouds from the list, as it is part of the topic directly above and is referred to by the same source.

Overall, the article could benefit from more additional references. ThomasUCI (talk) 04:59, 22 January 2017 (UTC)[reply]
