The Shoemaker crater in Western Australia, formerly known as the Teague crater, was renamed in honor of the planetary geologist Eugene Shoemaker for whom the Comet Shoemaker-Levy 9 is also named. The age of the crater unclear, but it could be 1.7 billion years old, which makes it the oldest known impact in Australia. The brightly colored splotches are seasonal salt-water lakes. This image was taken by the Landsat 7 satellite. Sphere: Related Content
