With regards to Wiki... maybe the image poster could quote any wiki content thats appropriate under the image giving wiki a credit of course and no need to leave the sight.(some of the wiki listing contain gobbledygook).

Wiki can be changed by anyone so not really trustworthy.

Generally, that's more of a problem with controversial subjects, where articles often suffer from change/revert wars (until they get locked for cooling-off...).
Descriptions of astronomical objects are, for the most part, not likely to be controversial, so they'll be as good (or bad) as the knowledge of the contributors make them.

Quotes should be fairly short (to be clear it's "fair use"), and include a link to the article (which effectively gives credit) for folk who want to read more. This goes for anything quoted from external sites.

You won't see one on your own posts, but everyone else's should have one...

I saw people were posting like emoji's in their posts, this doesn;t do that.

this doesn't do that

Thankfully, no it doesn't. It records who's clicked it, and tells the person whose post has been liked (which is the main point of having it). If a post has been liked then you can click on the "Liked by" link that appears there to see who has liked it, and if you've already liked a post then the "Like" link turns into an "unlike" link...

I can`t see the like button on any of my posts so won`t know how many likes are on them.

You will see how many people liked them. You just can't like them yourself.

See, for example, http://forum.orpington-astronomy.org.uk/index.php?topic=12513.msg89782#msg89782
