I took intro to astrophysics which was one of the hardest classes I’ve ever taken. Straight up weed out class lol. I ended up dropping it because I’m pretty sure I should have taken the physics sequence first (which was another grinder of courses). That stuff is interesting, though. My first job was on a cassini contract at Goddard. A lot of that team had phd’s…just a little bit above my pay grade lol.
If anyone here hasn’t viewed Saturn through a telescope, I advise it. It literally looks fake, but the fact that it’s not makes it awesome.
