If you are looking for something with a little more heft there is https://astrobites.org/2023/06/28/drop-the-bass-evidence-for-a-gravitational-wave-background-from-a-galaxy-sized-detector/ https://astrobites.org/2023/06/28/drop-the-bass-evidence-for... Astrobites articles are usually written by post-grad students working in the relevant area, with the writing level targeted at undergrad astrophysics students. This one was written by NANOGrav collab members, all (or at least most) of whom directly worked on the results that will be all over the press today and tomorrow, and maybe hits a level for an advanced undergrad student or so.
