YouTube Shorts exoplanet life script (about 40 seconds)
90 spoken words. The hook opens a mystery, the middle gives the mechanism, and the payoff closes on the idea that alien life may first appear as chemistry—not a signal.
HOOK: The first message from alien life may not be a message at all. MICRO REWARD: When a planet crosses its star, a thin ring of starlight passes through the atmosphere and leaves chemical fingerprints. ESCALATION: NASA says Webb can study gases such as water, carbon dioxide, oxygen, and methane. But one gas is not proof. Scientists need several clues, repeat observations, and years of modeling to rule out lifeless chemistry. PAYOFF: So the first evidence of life beyond Earth may arrive as a suspicious recipe in light from a world we can never touch.
The video handoff keeps the words unchanged and opens the closest supported preset (45 seconds) so there is room for natural pacing. Review before generating; nothing renders from this page.
Fact basis: NASA on atmospheric biosignatures and Webb transmission spectroscopy. NASA cautions that one signal is not a discovery; confirmation needs multiple lines of evidence.
