The paper was posted to the preprint server arXiv in June 2026.","The Moon’s surface has fine dust called regolith that keeps a long record of impacts and particles. The researchers say that studying one cubic metre of regolith could help test if past extraterrestrial technology left microscopic pieces on the Moon. They suggest using machine-vision tools and laboratory analysis to find unusual grains. Scientists also must check for Earth-made debris before claiming a find."],"wordCount":122,"readTime":2},"vocabulary":[{"word":"regolith","example":"The rover collected a small regolith sample.","phonetic":"/ˈrɛɡəˌlɪθ/","definition":"loose, broken rock and dust on the Moon's surface"},{"word":"particle","example":"We saw a tiny particle in the microscope.","phonetic":"/ˈpɑːr.tɪ.kəl/","definition":"a very small piece of matter"},{"word":"debris","example":"The site had metal debris from old missions.","phonetic":"/dəˈbriː/","definition":"broken pieces or waste left after an impact or crash"}],"quiz":[{"answer":"Lewis J.
