James Webb Pointed at Alpha Centauri… No One Expected What It Found

Описание: James Webb Space Telescope pointed at Alpha Centauri — the closest star system to Earth at just 4 light-years away — and found something no one expected. A faint dot of light appeared beside the star. Ten thousand times dimmer than Alpha Centauri itself. Then it vanished.

In this video, we take you through the full story: the ghostly first sighting in 2019, the engineering miracle that let Webb attempt these observations, the disappearing planet mystery, and what it means for humanity that our nearest stellar neighbor may not be empty.

What you'll discover:
► How James Webb Space Telescope used its infrared coronagraph to block starlight and reveal a hidden world
► Why the planet candidate disappeared in follow-up observations — and what millions of simulated orbits revealed
► What a Saturn-mass gas giant in the habitable zone of Alpha Centauri A actually means for life
► How the Nancy Grace Roman Space Telescope could confirm or deny this discovery
► What confirmation would mean for interstellar travel and the search for life beyond Earth

This is the closest a planet has ever been directly imaged to its host star. If confirmed, it would be the nearest exoplanet in the habitable zone of a Sun-like star ever found.
