Alien: Earth hits midseason with Episode 4 and a clear plan. In the U.S., the new chapter airs on FX at 8:00 p.m. ET / 5:00 p.m. PT on August 26, 2025, with streaming on Hulu. In the U.K., it drops on Disney+ at 1:00 a.m. BST on August 27. The episode is titled “Observation.” The Scotsman also notes that the season spans eight episodes and is released weekly.
