Svemirski teleskop prošlost: James Webb i rub svemira

Saznajte zašto svaki teleskop zapravo gleda u prošlost i kako James Webb hvata svjetlost koja je putovala više od 13 milijardi godina. Dokumentarac prati fizikalne temelje te sposobnosti — od Rømerova mjerenja brzine svjetlosti do spektroskopskog potvrđivanja galaksija starih samo 290 milijuna godina. Prikazani su i inženjerski izazovi izgradnje i rasklапanja teleskopa, kao i otvorena pitanja koja Webb postavlja pred standardni kozmološki model.
