Discover how NASA's Landsat 9 image of Australia's Spider Crater reveals a giant spider-like shape in the Kimberley region. Learn why the 13 by 11 kilometre oval, with a 4 kilometre spider-like centre, is the eroded remains of an ancient meteorite impact, how its central uplift and light sandstone ridges formed its legs, and why shatter cones and shocked quartz proved it was an impact and not a volcano. The impact happened about 900 to 600 million years ago, and its rocks still carry the evidence today.
