Los científicos utilizan la Luna para estudiar un asesino de dinosaurios

Los científicos utilizan la Luna para estudiar un asesinoThe Moon's 320-kilometer-diameter Schrödinger basin is the best preserved impact basin of its size. Its broad flat floor offers several safe landing sites, and the geology within the basin is extraordinary. The 2.5-kilometer-high peak ring is 150 kilometers in diameter. During the impact event, rock rose from deep within the lunar crust and towered briefly in a central peak over the lunar surface before collapsing downward under the influence of gravity and flowing to form the mountainous peak ring seen today. A similar process is envisioned for the Chicxulub crater on Earth, which is related to the extinction of dinosaurs 66 million years ago.
