James Webb Peered Too Close to Home… and They Wished It Hadn't
In 2017, an astronomer at NASA sent his colleagues an email that opened with a line he knew would get him laughed at: "When you stop laughing, let's think about doing this project." The plan was to photograph a planet around Alpha Centauri A, the closest sun-like star to Earth, with a telescope that had not even launched yet.
In August 2024, the James Webb Space Telescope did exactly that. It found a faint point of light right where a planet should be. Then, when the team looked again in 2025, it was gone. Twice.
In this video I walk through the whole story: the 2019 signal nobody could confirm, the 2024 detection, the two empty images that should have killed it, and the orbital simulation that turned the disappearance into evidence instead of a dead end. Then the skeptics get their say, because Alpha Centauri has fooled astronomers before. And there is one date that decides it: August 2026.
This is a candidate, not a confirmed planet. Every claim here comes from the peer-reviewed papers and the researchers themselves, and the sources are below.
