I don't understand this comment. Like yes, 3000 stars per second, cool fact. But why would that fact make sense in the article? The article was about being surprised by the name "SN 2021 afdx", which has nothing to do with star formation.
In my opinion the article was great and is also complete. More cool astronomy facts belong in some other article or format.
Because the amount of stars that can go supernova is limited by how many stars there are in the first place? A comment about the staggering rate of star formation makes sense to me in relation to an article about the staggering rate of star supernovas..
