The TV show Alien: Earth aired its fourth episode, "Observation," on 25 Aug 2025. The story focuses on a strange alien called Species 64, which can take over hosts by replacing their eyeballs. This alien attacked a synthetic being named Nibs, showing it might feed on intelligence, not flesh. Other aliens in the show mostly target humans, but Species 64 could be more dangerous to synthetic beings who have advanced brains. Wendy, a hybrid character, can communicate with baby Xenomorph aliens, showing a unique connection. The episode raises questions about the safety of synthetic beings and the ethics of the Prodigy company’s experiments. The series is available on FX and Hulu, with new episodes every Tuesday until 9 Sept. (Updated 28 Aug 2025, 04:36 IST; source: link)
