science π Quebec astronomer finds huge impact crater
An amateur astronomer in Quebec spotted a nearly circular ridge pattern in satellite imagery during a 2024 camping trip. This feature, about 25 kilometres across near Lake Marsal, was submitted to Impact Earth, a research project. Researchers confirmed it in October 2025, finding shatter cones and impact melt rock. The structure, provisionally named Uhackatik, is estimated to date back to the Devonian period, around 390 million years ago. Formal recognition is pending as the team presented findings in August 2026. π
