Do you guys know any sci-fi novels about space travel/cosmic exploration fantasy

I picked up this book from a bookstore called ‘Star Maker’ by Olaf Stapledon. It’s not necessarily a novel (because there is no story or characters) but I enjoyed reading it, and I wanna read more sci-fi books. But im specifically more into space travel type of story. Do you guys know any?
