In Australia, experts are puzzling over the origin of a mysterious object that has washed up on a beach north of Perth. It is a kind of cylindrical canister made of light carbon fiber material that is almost three meters high and 2.5 meters wide, the ABC broadcaster reported on Tuesday. A detailed check by experts has shown that the object is safe and poses no danger to people, the police said. However, local residents have been urged to stay away from the mysterious, gold-hued part.

Meanwhile, the Australian Space Agency also tried to help with the identification. “The object could come from a foreign launch vehicle,” the agency wrote on Twitter. “We are in contact with international partners who may be able to provide more information.” Western Australia state officials were ordered away from guarding the cylinder “to ensure the preservation of potential evidence and to facilitate further expert scrutiny.”
