    A giant ring system around a substellar object causes a rare nine-month eclipse of its host star
    An international scientific team, involving the University of La Laguna (ULL) and the Instituto de Astrofísica de Canarias (IAC), has identified the cause of an unusually long dimming of a distant star . The phenomenon is explained by the passage of a substellar object with a giant ring system, similar to a ‘cosmic saucer’, in front of the host star. The star, named ASASSN-24fw, is located in the Monoceros constellation at about 3,000 light-years away from Earth. The star faded steadily for more than nine months between late 2024 and mid-2025 to about 97% dark before returning to its normal
