In *The War of the Worlds*, Earth’s bacteria kill the Martians
AI-generated cover: symbolic blank novel, microscope view of bacteria-like forms, and Mars-like landscape. The microbes are fictional visual symbolism, not evidence of life beyond Earth. Prompt: “Photorealistic editorial cover for H. G. Wells's fictional ending in The War of the Worlds and modern astrobiology: antique blank science-fiction book beside a microscope view of tiny bacteria shapes, with a muted Mars-red landscape in the background, vertical 4:5. No readable text, real book cover, named microbes, or claim life has been discovered beyond Earth.” Generated 2026-10-19.
In H. G. Wells’s 1898 novel *The War of the Worlds*, Earth’s bacteria ultimately stop the Martian invasion: the visitors have no defenses against Earth’s disease-causing microbes. This is the novel’s fictional explanation for its ending. Today, NASA investigates whether ancient microbes may once have existed on Mars, while the Europa Clipper mission studies whether icy Europa has conditions suitable for life; these are scientific investigations of possible environments, not confirmation of extraterrestrial life.
