Life on other planets: What alien civilizations could look like?

What would life look like on a planet with almost no light? We've been searching for a "blue marble" like Earth. But most exoplanets orbit dim red dwarf stars — where chlorophyll-based photosynthesis is useless. In this short video, we explore a scientific hypothesis: Alien plants wouldn't be green — they'd be pitch-black or deep purple to absorb all available light. Alien animals would likely be blind and rely on vibration, echolocation, or magnetic fields. Intelligent aliens might have no eyes at all — building civilizations based on sound and electrical signals, not light. This is convergent biology and astrobiology speculation — grounded in real science, not science fiction.
