What the record says

  • The OLI instrument on the NASA-USGS Landsat 9 satellite captured the image on Sept. 20, 2026.
  • NASA says the full structure is oval, about 13 km by 11 km (8 by 7 miles), with a central portion about 4 km (2.5 miles) across.
  • The light-colored “legs” are sandstone ridges left after other rock layers in the impact zone eroded.
  • Geologists confirmed the impact origin from shatter cones, fractures that form only when intense shock waves pass through rock.
