Astounding Stories Nov 1931: Glowing Alien Entity Attacks Fallen Man

Surprisingly visceral for 1931, this cover depicts a luminous, jellyfish-like alien energy creature coiling menacingly around a prostrate victim while two armed men recoil in horror — one reaching desperately toward the fallen figure. The glowing orange-red orb at the creature's core pulses with eerie bioluminescence against a chaotic blue-green laboratory backdrop, making the monster feel genuinely otherworldly rather than merely mechanical, a bold choice when robots and rockets dominated most pulp covers of the period.
