Are weekly raids/dungeons still a thing?

Im coming back to the game after almost 2 years, i remember back then there used to be a certain raid/dungeon that was grindable, ive tried to look into it but i havent found anything about it recently

no weekly thing anymore, all raids are now farmable, all challenges active, master mode available, though the exotics are not farmable
