Zolium
From superman.nu: Supermanica
Zolium
The planet Jimmy Olsen visits when he is accidentally transported from Earth inside an experimental rocket hurled by Superman.
The "density of the atmosphere" and "peculiar refraction of rays and light intensity" on Zolium combine to grant Olsen super-powers. The humanoid inhabitants of Zolium have the power of telepathy (SPJO No. 39/1, Sep 1959: "The Super-Lad of Space!").
