NASA scientists at the Southwest Research Institute discovered a 29th moon orbiting Uranus while using infrared detection through the Webb Space Telescope.

NASA scientists at the Southwest Research Institute discovered a 29th moon orbiting Uranus while using infrared detection through the Webb Space Telescope.

Scientists think the new tiny moon hid for so long -- even eluding the Voyager 2 spacecraft during its flyby about 40 years ago — because of its small size.

Der siebte Planet hat damit jetzt 29 Monde. S/2025 U1 ist nur etwa zehn Kilometer groß. Weitere Entdeckungen sind wahrscheinlich, vermuten die Forscher.
