Brian Cox leads Solar System, a 2024 documentary series that turns decades of spacecraft imagery and freshly rendered visual effects into a guided tour of the planets, their moons, and the wreckage left over from the solar system's violent birth.
What is Solar System about?
Across its episodes, the production follows Cox from observatories and mission archives to render each world in unprecedented detail, tracing how gravity, collision, and time shaped neighbors as different as scorched Mercury and the icy moons circling Saturn and Jupiter. Rather than treating the planets as static postcards, the series builds a running argument about how the solar system's chaotic early history still shapes the skies overhead tonight, drawing on footage gathered by orbiters, landers, and telescopes engineered to answer the very questions Cox raises on camera. The result reframes familiar worlds as active, changing places rather than fixed points on a chart.
About the cast
Professor Brian Cox anchors every episode as host and narrator, drawing on his background as a physicist to translate mission data and telescope imagery into an accessible on-screen argument. His presence gives the series a consistent voice across its planetary case studies, setting it apart from anthology-style space documentaries that rotate narrators from episode to episode.
Context & significance
Solar System comes from British and American production teams and leans on archival spacecraft photography alongside newly rendered visuals, a pairing increasingly common in high-end science documentaries built to make decades-old missions feel current again. Following a run of other Brian Cox-fronted science programming, it continues a house style built around a single trusted expert host rather than an ensemble of rotating talking heads explaining the same material.
Watching Solar System on Ktime
K-Time carries Solar System with a Persian dub and Persian subtitles, letting Farsi-speaking viewers follow Cox's explanations without leaning on the original English narration. The page itself is free to browse; watching the episodes only requires a free K-Time account login, with the Farsi-language interface built for diaspora audiences who want science programming presented on their own terms.
