The Invincible, first edition 1964, Stanislaw Lem (the author of Solaris)
The very powerful and armed interstellar 2nd-class cruiser Invincible, lands on Regis III which seems bleakly uninhabited, to investigate the loss of sister ship, Condor. The crewmen of the Invincible explore the planet, with the help of robots and satellites. The planet has an almost breathable atmosphere for humans, but curiously, there is life only in the oceans. On the ground there are remains of strange metallic structures.
I read this book in a French translation. This is a relatively hard science novel focused on exploration and scientific mystery rather than the individual characters, but this is accessible and interesting. This is well written, there is suspense and mystery. One chapter is particularly epic and the revelations are satisfying and relatively original, even today (the theme was very new at the time). The book is about a mystery, so this is difficult to talk about it without giving spoilers.
This is not a well known book, I think. The summary on wikipedia is very brief. So, I wrote here a longer summary with spoilers. I recommend to read the novel instead, but If you can’t find it easily, and want to know more about it, that can give you a (pale) idea of the story.
