I guess what he is talking about is that you linked the image (https://apod.nasa.gov/apod/ image /2602/PIA20522enceladus .jpg ), but not the actual blog post (https://apod.nasa.gov/apod/ap260207.html (be sure not to include /fap/ in the link)) that include the textual information.
I am not sure if the image will show when adding the blog post as a link (instead of the image link), but when using the image link it is nice to add the blog post seperately. I think the blog post would be more valuable than the individual organisations underneath.
I commend you are adding sources! Thank you :)









Note that your link directs to the latest post. I think it is because of the
/fap/. If that is removed it works fine. I think that’s a bit of a messy system that APOD uses.
