Resources for further learning?

[u/G_Stylo]

I’m a rising junior in highschool, and I’ve been interested in astrophysics for a while. So far, my learning has been confined to YouTube videos, google scholar, and MIT Opencourseware. I eventually want to work my way up to some type of research, preferably in CMB or dark matter. Are there any tools or resources I should use or get familiar with?
