When dinosaurs roamed Earth 214 million years ago, an asteroid 3 miles wide struck what is now Canada. In southeastern Québec lies Manicouagan Crater, one of the world’s largest and oldest impact craters. Today, the remnants of the crater are made visible by water and, sometimes, ice. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite on January 20, 2022.
