At the edge between eternal day and eternal night on a distant gas giant, humanity's most powerful space telescope has found that twilight is not uniform — that the boundary where a world's morning meets its evening carries distinct chemical and thermal signatures shaped by winds, heat, and molecular transformation. Astronomers studying WASP-121 b, a planet locked in permanent extremes some 880 light-years away, have used the James Webb Space Telescope to separate the atmospheric signals of its dawn and dusk sides during a single transit, revealing an asymmetry that challenges the long-held pr
