New images of Fomalhaut confirm that an alleged planet is probably just dust while also revealing a new asteroid belt and a “Great Dust Cloud.”
Rings of dust encircle the young star in stunning new images from the James Webb Space Telescope. The photos offer a clearer view of the star system — already famous for previous images of a purported, now widely disputed, planet.
But just because Dagon hasn’t seemed to have panned out, that doesn’t mean there aren’t other planets lurking around Fomalhaut. “This is a truly unique aspect of the system,” Gáspár says. The tilted belt, he says, could be the result of as-yet-undiscovered planets stirring up the debris around Fomalhaut.
The JWST images also turned up a newly identified feature in the outer belt around the star. It’s a blob that Gáspár and his colleagues call the Great Dust Cloud. It’s not yet clear whether it’s a real feature, or just some bright object shining through from beyond the Fomalhaut system.
