I always enjoy reading articles from https://www.quantamagazine.org and https://nautil.us . They are really well written, insightful (but not too technical) and nicely illustrated.

Quanta articles are free to read. Unfortunately, Nautilus is behind a paywall after 2 free articles/month and it seems that contributers have not (yet?) gotten the money they deserve: https://en.wikipedia.org/wiki/Nautilus_Quarterly#Controversy I have not looked more closely into the matter, since I don’t read their articles very often, but may be worth considering if you decide to subscribe.
